2. Five Key Advantages of the No.80-3 American Sprocket<\/h2>\n
\n
\n

\u2460 Triple-Strand Capacity Without Changing Shaft Geometry<\/strong><\/p>\n

The No.80-3 triplex configuration delivers three times the load capacity of a single-strand No.80 American Sprocket while keeping the pitch circle diameter and shaft centre distance identical to the simplex equivalent. This allows machine designers to uprate drive capacity on existing equipment layouts by replacing the simplex chain-and-sprocket pair with a triplex set \u2014 without relocating shafts, modifying frames, or moving to a larger pitch. This is one of the most cost-effective upgrades available in American sprocket engineering.<\/p>\n<\/div>\n

\n

\u2461 ANSI B29.1 Verified Tooth Profile Across All 85 Tooth Counts<\/strong><\/p>\n

Every american sprocket in the No.80-3 series is CNC-machined and coordinate-measured against ANSI B29.1 before dispatch. The 0.625-inch roller diameter, 1-inch pitch, and ANSI-specified tooth form are held within tolerance across the complete Z=11\u2013Z=95 range. For industrial buyers sourcing american sprockets for sale as OEM build components or replacement parts, this conformance verification eliminates dimensional uncertainty at installation and supports warranty documentation for the host machine.<\/p>\n<\/div>\n

\n

\u2462 Type B and Type C Hub Options for Flexible Mounting<\/strong><\/p>\n

The No.80-3 series american sprocket provides two hub configurations tailored to different sprocket sizes and mounting requirements. Type B sprockets (Z=11\u2013Z=36) feature an extended hub on one side, maximising bore depth for shaft engagement in small-diameter sprockets where hub length would otherwise limit keyway engagement. Type C sprockets (Z=42\u2013Z=95) use a centred hub geometry suited to larger pitch diameter sprockets where balanced load distribution across both shaft bearings is the priority. This dual-configuration approach is a defining characteristic of well-engineered american standard chain sprockets.<\/p>\n<\/div>\n

\n

\u2463 Carbon Steel with Induction-Hardened Tooth Flanks<\/strong><\/p>\n

Standard material is carbon steel produced and machined to the quality level required by ANSI B29.1 for industrial chain drive sprockets. Tooth flank induction hardening achieves surface hardness in the HRC 45\u201355 range while preserving a tough core that absorbs shock loading without fracture \u2014 the dual-property combination that separates precision industrial sprockets and gears from commodity cast components. What is the best steel for sprockets? Carbon steel with induction hardening consistently outperforms plain steel, aluminium, and plastic alternatives in the load and duty ranges where No.80-3 American Sprocket is typically specified.<\/p>\n<\/div>\n

\n

\u2464 Stock Bore for Immediate Dispatch \u2014 Full Custom OEM Capability<\/strong><\/p>\n

Stock bore configurations covering the full Z=11\u2013Z=95 range are available for immediate dispatch, supporting urgent MRO requirements without machining lead times. For custom sprocket manufacturer programmes needing specific bore sizes, keyways, QD (Quick-Detachable) bushing bores, or non-standard hub configurations, our engineering team machines to customer drawing. The combination of immediate stock availability and engineered-to-order custom manufacturing makes us a reliable single-source industrial sprockets and gears supplier for both scheduled production and emergency replacement requirements.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

3. How the No.80-3 American Sprocket Transmits Power<\/h2>\n

The American sprocket operates on the same positive-engagement principle as all roller chain sprockets \u2014 each tooth enters the chain from below and seats a chain roller in the tooth gullet, transferring driving force through direct contact between the tooth flank and the roller surface. What distinguishes the No.80-3 triple-strand configuration is that three separate chain strands engage simultaneously on three parallel sets of tooth rows, all sharing the same pitch circle. The torque load is shared across all three strands, reducing the tension in each individual chain to one-third of what a single-strand drive would require at the same shaft torque \u2014 which in turn reduces fatigue stress on chain links, pins, and roller contact surfaces.<\/p>\n

In the No.80-3 American Sprocket, the 1-inch pitch governs the angular distance between tooth centres on the sprocket. This pitch, combined with the 0.625-inch roller diameter and the ANSI B29.1 tooth form, determines the geometry of the tooth pocket \u2014 specifically, the root radius, flank angle, and clearances that govern how each roller seats during engagement and releases during disengagement. ANSI B29.1 specifies these parameters in detail, and the CNC machining of our No.80-3 American Sprockets holds the critical dimensions within ANSI tolerance limits to ensure that new sprockets engage ANSI No.80 chain correctly on first installation, without requiring a wear-in adjustment period.<\/p>\n

The transition between Type B and Type C hub configurations across the tooth count range reflects a practical engineering consideration. In smaller sprockets (Z=11\u2013Z=36), the boss diameter relative to the outer diameter is large, making an extended single-side hub (Type B) the natural configuration \u2014 it provides maximum bore depth for shaft engagement without creating stress concentration at the tooth root. In larger sprockets (Z=42\u2013Z=95), the outer diameter is large enough to accommodate a centred hub (Type C) that distributes the shaft load symmetrically across both bearing positions, reducing bending moments on the drive shaft at large sprocket diameters. This hub transition is a standard feature of American made sprockets in the medium-heavy duty chain range.<\/p>\n<\/div>\n

<\/p>\n

\n

4. Material Specification and Surface Treatment<\/h2>\n

The standard material for the No.80-3 American sprockets is carbon steel conforming to the material requirements of ANSI B29.1. This alloy is selected for its combination of machinability to close tooth profile tolerances, hardenability under induction treatment, and toughness under the shock and impulse loading that characterises triple-strand drives in heavy conveyor and materials handling applications. Tooth flanks are induction-hardened to HRC 45\u201355 while the core retains a ductile, fatigue-resistant microstructure \u2014 the specific combination of properties that determines long-term service life in industrial roller chain drives.<\/p>\n

What sprocket is better, aluminum or steel? For the load levels associated with No.80-3 triple-strand drives \u2014 which handle the torque of three simultaneous chain strands under industrial duty cycles \u2014 steel is the only appropriate structural material. Aluminium sprockets are appropriate for lightweight, low-torque applications such as bicycle or lightweight automation drives where mass reduction takes priority over load capacity; they are not rated for the weight loads, shock duty, and thermal cycling associated with industrial conveyors, agricultural equipment, or material handling systems. Steel stock sprocket components in the No.80-3 range are specified precisely because no alternative material meets the load rating requirements at comparable cost.<\/p>\n

For applications where corrosion resistance is required in addition to structural performance \u2014 food processing lines, chemical conveying equipment, and coastal or tropical installations in Colombia and Latin American markets \u2014 stainless steel sprockets and gears in AISI 316 are available. The tooth geometry is identical to the carbon steel range, allowing direct material substitution without drive re-engineering. Surface treatment options for the standard carbon steel range include black oxide (producing the black kettenrad zahnrader finish) for modest corrosion protection with negligible dimensional change, and zinc phosphate with oil for improved rust inhibition during tropical-climate storage and transit.<\/p>\n<\/div>\n

5. \u049a\u043e\u043b\u0434\u0430\u043d\u0443 \u0441\u0446\u0435\u043d\u0430\u0440\u0438\u0439\u043b\u0435\u0440\u0456<\/h2>\n

The No.80-3 triple-strand American sprocket occupies the medium-heavy duty segment of the industrial chain drive market. Its applications are defined by the need for high torque capacity within the 1-inch pitch envelope \u2014 situations where a simplex or duplex chain would require unacceptable chain tension or shaft loading to handle the required power.<\/p>\n

\n
\n

Heavy Conveyor Drives \u2014 Manufacturing and Warehousing<\/strong><\/p>\n

Pallet conveyors, heavy-duty roller conveyors, and transfer systems in manufacturing plants and distribution centres use No.80-3 sprockets in head-shaft and tail-shaft positions where the combined weight of loaded pallets and conveyor structure creates sustained chain tension beyond simplex chain capacity. The triple-strand configuration distributes this tension across three chains, keeping individual chain loads within the service factor limits recommended by ANSI B29.1 for continuous-duty industrial conveyor applications. Industrial sprockets and gears in this size range represent the highest-volume replacement part category in heavy conveyor maintenance programmes.<\/p>\n<\/div>\n

\n

Agricultural Equipment \u2014 Colombia and Latin America<\/strong><\/p>\n

American-built combines, grain augers, cotton pickers, and sugar cane harvesters exported to Colombia and other Latin American markets predominantly use ANSI B29.1 chain standards \u2014 making the No.80-3 one of the most-requested replacement kettenrad zahnrader equivalents in the regional agricultural machinery parts market. Field maintenance teams servicing American-standard equipment in Colombia should verify the chain designation (No.80 on the chain side plate) and strand count before ordering replacement sprockets, as European DIN 8187 chains of similar pitch are dimensionally incompatible. Our stock bore range allows rapid replacement dispatch to Colombian buyers without custom machining lead times.<\/p>\n<\/div>\n

\n

Mining and Quarry Equipment Drives<\/strong><\/p>\n

Underground mining haulage conveyors, surface stockpile reclaimers, and quarry belt feeder drives frequently specify No.80-3 roller chain sprockets for their final drive positions. The triple-strand configuration is particularly valued in these applications because it allows higher horsepower to be transmitted through a relatively compact 1-inch pitch chain without moving to the bulkier No.100 or No.120 pitch sizes that require heavier shaft and bearing arrangements. The hardened-tooth carbon steel construction handles the intermittent shock loading typical of mining conveyor start-up cycles without the brittleness risk associated with fully hardened through-hardened steel.<\/p>\n<\/div>\n

\n

Food Processing and Packaging Lines<\/strong><\/p>\n

Heavy-duty food processing lines \u2014 meat deboning conveyors, fish meal cookers, and large-format packaging machines \u2014 use triple-strand American sprockets in main drive positions where load exceeds the simplex chain rating. Stainless steel sprockets and gears in AISI 316 are available for this series for wash-down positions, supporting compliance with HACCP requirements and EU Regulation 1935\/2004 for food-contact materials. For Colombian food processing plants importing American-standard equipment, stock bore sprockets in the No.80-3 range enable quick replacement without extended machine downtime.<\/p>\n<\/div>\n

\n

Bucket Elevator and Grain Handling Systems<\/strong><\/p>\n

Bucket elevator head and boot shaft drives in grain elevators, feed mills, and cement plants use large-tooth-count No.80-3 sprockets \u2014 typically Z=42 through Z=95 \u2014 in the Type C hub configuration. The slow-speed, high-torque loading profile of elevator drives benefits directly from the triple-strand capacity distribution, keeping individual chain tensions within the service limits that govern fatigue life in continuous-duty elevator operation. Buyers across North America, Colombia, and the broader Americas region sourcing american sprockets sizes for elevator replacement should reference the tooth count and outer diameter from the existing sprocket before ordering.<\/p>\n<\/div>\n

\n

Oil and Gas Field Equipment<\/strong><\/p>\n

Pumping units, rod lift systems, and wellhead auxiliary drives in oil field operations use heavy-duty American metric sprocket configurations where reliable chain engagement under high-cycle, high-load conditions is essential. The No.80-3 double chain sprocket gear arrangement covers the load range of these drives and is frequently specified for new installations where ANSI B29.1 chain systems are the project standard. Replacement sprocket manufacturer supply capability with stock bore availability reduces equipment downtime on producing wellsites where delays carry significant operational cost.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

6. Standards and Regulatory Framework<\/h2>\n

Procurement of American standard chain sprockets for use in regulated industries or across multiple markets involves compliance with the applicable mechanical safety and materials standards of each jurisdiction. The following framework covers the key regulatory requirements for the No.80-3 series.<\/p>\n

\n
\n

ANSI\/ASME B29.1 \u2014 American Chain Standard<\/strong><\/p>\n

The primary governing standard for roller chain and sprocket dimensions in the American market. ANSI B29.1 specifies pitch, roller diameter, inner link width, and sprocket tooth profile tolerances for all No.80 designation components. All American Sprockets in our No.80-3 series are verified to ANSI B29.1 with dimensional records available for OEM technical files and ASME machinery compliance submissions.<\/p>\n<\/div>\n

\n

OSHA and ASME B15.1 \u2014 USA Machinery Guarding<\/strong><\/p>\n

In the United States, chain and sprocket assemblies installed in machinery must comply with OSHA 29 CFR 1910.219 (mechanical power transmission guarding) and ASME B15.1 safety standards, which require appropriate guards on all exposed chain drives accessible to personnel. Specifying ANSI B29.1 conformant american sprockets is the dimensional baseline for demonstrating that the chain drive meets the safeguarding requirements applicable under OSHA inspection.<\/p>\n<\/div>\n

\n

Colombia \u2014 Icontec NTC and Ministry of Labour<\/strong><\/p>\n

In Colombia, machinery safety is governed by Ministerio del Trabajo resolutions referencing applicable ISO and ANSI standards. Industrial chain drives installed in Colombian facilities \u2014 particularly in mining, food processing, and agricultural sectors \u2014 must meet the operational safety requirements of the applicable NTC standard, which for ANSI chain drives generally references ANSI B29.1 directly. Our material and dimensional documentation supports Colombian buyers’ compliance submissions to national regulatory bodies.<\/p>\n<\/div>\n

\n

EU Machinery Directive 2006\/42\/EC (for export to Europe)<\/strong><\/p>\n

For American sprockets exported into EU markets and installed in CE-marked machinery, the ANSI B29.1 chain dimensions are not directly covered by EN harmonised standards \u2014 the equivalent European standard is DIN 8187. Machinery incorporating No.80-3 American Sprockets in an EU market typically requires a technical justification in the machine technical file demonstrating equivalent safety to the harmonised standard. Our engineering team can provide the dimensional comparison documentation needed for this justification.<\/p>\n<\/div>\n

\n

MSHA \u2014 US Mining Safety and Health Administration<\/strong><\/p>\n

Chain drive components in underground mining applications in the United States are subject to MSHA regulations requiring that all drive components are maintained in safe operating condition and that replacement parts meet the original dimensional and material specifications. Our ANSI B29.1 conformant No.80-3 American Sprockets satisfy the “equivalent replacement” requirement that MSHA inspectors apply to chain drive maintenance documentation in regulated mining operations.<\/p>\n<\/div>\n

\n

Food Safety \u2014 FDA 21 CFR and INVIMA (Colombia)<\/strong><\/p>\n

For food processing applications in the US, chain drive components in food-contact or food-adjacent positions may fall under FDA 21 CFR material requirements. In Colombia, INVIMA oversees food contact materials in processing equipment. Our AISI 316 stainless steel No.80-3 American Sprockets are available with material certificates and can be supplied with compliance declarations supporting both FDA and INVIMA documentation requirements.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Every American sprocket tooth profile is verified against ANSI B29.1 (or the applicable European or Asian standard) before dispatch, with dimensional records retained for customer OEM technical files. Gear tooth accuracy is documented to DIN 3961 \/ ISO 1328 quality grades for gear components. Our catalogue spans all three major roller sprocket standards \u2014 American ANSI\/ASME, European DIN\/ISO, and Asian JIS \u2014 as well as a complete gear range per DIN 782 covering spur gears, bevel gears, and racks. Whether the requirement is a standard stock bore american sprocket for same-week dispatch, or a fully engineered custom sprocket manufacturer output for an OEM production programme, our manufacturing and inventory capability covers both without minimum order constraints on repeat design numbers. For industrial buyers across Colombia, the United States, and international markets, we are a reliable single-source chains and sprockets supplier for medium-heavy duty drive systems.<\/p>\n

8. System-Compatible Components<\/h2>\n

A triple-strand sprocket performs to its ANSI B29.1 specification only when paired with correctly specified drive components. We supply matched system components \u2014 chain and reducer \u2014 from the same quality framework as the sprockets, removing the compatibility risk that arises from multi-supplier procurement across different standards.<\/p>\n

ANSI No.80 Triple-Strand Roller Chain<\/strong><\/p>\n

An ANSI B29.1 No.80 triple-strand roller chain is the essential counterpart to the No.80-3 sprocket. The chain must match in pitch (1 inch), roller diameter (0.625 inch), and strand count \u2014 using a simplex or duplex chain on a triple-strand sprocket results in immediate misalignment and premature wear. Our roller chains<\/a> are manufactured to ANSI B29.1 with all critical dimensions within the tolerance window governing the sprocket tooth pocket geometry. For buyers sourcing chains and sprockets as a matched triple-strand set, a single combined conformance declaration covering both chain and sprocket dimensions can be provided, simplifying incoming inspection for quality-managed procurement operations in Colombia and across North America.<\/p>\n

Most No.80-3 chain drives receive their speed reduction through a gear reducer positioned between the prime mover and the drive sprocket shaft. Our NMRV worm gear reducers are available in output shaft diameters and keyway configurations that align with the bore ranges used across the No.80-3 series \u2014 from the 1-inch minimum bore at Z=11 up to the 4.5-inch maximum bore at Z=95. Specifying sprockets and reducer together from a single supplier allows our engineering team to confirm shaft diameter, keyway, and output speed before delivery, eliminating the dimensional mismatches that most commonly appear during chain drive commissioning when components are sourced independently. For sprockets and gears near me buyers across the Americas region, this one-stop sourcing approach reduces procurement lead time and coordination effort significantly.<\/p>\n

\nQ1. What is the difference between an American sprocket and a European standard sprocket for industrial conveyor applications?<\/summary>\n
American sprockets conform to ANSI\/ASME B29.1, which uses inch dimensions \u2014 the No.80 series American Sprocket has a 1-inch pitch and a 0.625-inch roller diameter. European standard sprockets conform to DIN 8187 \/ ISO\/R 606, which uses metric dimensions and different roller diameters for the same nominal pitch. The two standards are dimensionally incompatible: using an ANSI No.80 chain on a DIN 08B sprocket \u2014 or vice versa \u2014 causes incorrect roller seating, uneven load distribution, and rapid wear on both chain and sprocket teeth. Always confirm which standard the original equipment uses before ordering replacement sprockets for industrial conveyor applications.<\/div>\n<\/details>\n
\nQ2. What is the difference between a Type B and a Type C hub American sprocket and how do I know which one my machine uses?<\/summary>\n
Type B American sprockets have a boss (hub) that extends on one side of the sprocket face only \u2014 this is the standard for smaller tooth counts (Z=11\u2013Z=36 in the No.80-3 series American Sprocket) where the hub diameter relative to the outer diameter requires maximising bore depth on one face. Type C sprockets have a hub that is centred symmetrically on the sprocket \u2014 standard for larger tooth counts (Z=42 and above) where the pitch circle is large enough to accommodate a balanced hub that minimises bending moment on the shaft. On your existing sprocket, examine the hub position relative to the tooth face: offset to one side is Type B; centred is Type C.<\/div>\n<\/details>\n
\nQ3. What is a sprocket and how is it different from a gear in a heavy-duty industrial power transmission system?<\/summary>\n
What is a sprocket? A sprocket is a toothed wheel designed to engage a roller chain \u2014 the tooth pockets are shaped to receive the chain rollers, and the chain transmits force between the sprocket and the driven shaft across a variable centre distance. A gear, by contrast, meshes directly with another gear tooth, requiring a fixed, precisely controlled centre distance. In industrial machinery, the difference between gears and sprockets determines where each is used: gears in high-speed, compact reduction stages; sprockets and chains in final drives where long shaft separations, layout flexibility, or high torque at low speed are required. The No.80-3 American sprocket serves the latter role in medium-heavy duty applications.<\/div>\n<\/details>\n
\nQ4. How do I identify the correct American sprocket sizes when the original part number is not visible on the sprocket?<\/summary>\n
Without a visible part number, measure the chain pitch across 10 chain links and divide by 10 \u2014 a result close to 1.000 inch confirms No.80 chain. Count the sprocket teeth and measure the outer diameter; cross-reference against the De column in the dimensional table above to confirm the tooth count. Check whether the hub is offset to one side (Type B) or centred (Type C). Finally, measure the bore diameter and note the keyway. With tooth count, hub type, bore, and keyway in hand, you can identify the correct No.80-3 replacement from the part number table \u2014 for example, E80C60 for a 60-tooth Type C sprocket.<\/div>\n<\/details>\n
\nQ5. Which is better for an industrial sprocket application \u2014 aluminum or steel, and when does stainless steel make sense?<\/summary>\n
What sprocket is better, aluminum or steel? For No.80-3 American Sprocket industrial applications, carbon steel is the only appropriate material \u2014 aluminium sprockets are not rated for the load levels involved in triple-strand 1-inch pitch drives. Stainless steel sprockets and gears are appropriate when corrosion resistance is the primary design constraint, such as food processing wash-down zones, chemical handling, or humid coastal environments in Colombia. Stainless steel provides adequate structural performance for the loads involved but has a lower hardness ceiling than induction-hardened carbon steel, so its tooth life under sustained heavy loading is somewhat shorter. For environments where both high load and corrosion resistance are required, induction-hardened AISI 316 stainless is the preferred choice.<\/div>\n<\/details>\n
\nQ6. Where can I find industrial sprockets and gears near me in the Americas region that stock the full No.80-3 range?<\/summary>\n
For buyers seeking gears and sprockets near me across North America, Colombia, and the broader Americas, the most reliable sourcing approach for the full No.80-3 tooth count range (Z=11\u2013Z=95) is to contact a direct-manufacturing stockist that holds standard bore inventory and can manufacture custom configurations on short lead times. Distributor networks often carry only the most common tooth counts (typically Z=11\u2013Z=30). For Colombian buyers, direct international sourcing from a certified manufacturer with established Americas freight logistics provides cost and lead-time advantages over sourcing through regional distributors who may hold only partial stock.<\/div>\n<\/details>\n
\nQ7. What is the american standard vs new american standard chain designation system and how does it affect sprocket selection?<\/summary>\n
The american standard vs new american standard distinction refers to the evolution of ANSI\/ASME B29.1 through successive revision cycles. Earlier ANSI editions specified slightly different roller diameter and inner link width tolerances compared to current editions. For most practical replacement sprocket applications, current ANSI B29.1 conformant sprockets are dimensionally compatible with chain manufactured to earlier ANSI editions in the same pitch designation. However, buyers replacing sprockets on machinery manufactured before approximately 1985 should verify the roller diameter of the existing chain, as some pre-revision chains used slightly different roller sizes that may produce marginally different engagement with current-specification sprockets.<\/div>\n<\/details>\n
\nQ8. How do I calculate the gear ratio for a new conveyor drive in Colombia using No.80-3 American sprockets?<\/summary>\n
The gear ratio of any chain drive is the ratio of driven sprocket teeth to drive sprocket teeth. For example, pairing a Z=30 driven sprocket with a Z=15 drive sprocket gives a 2:1 reduction \u2014 the output shaft turns at half the input shaft speed with double the torque. To calculate output shaft speed, divide the input RPM by the gear ratio. For a new Colombian conveyor installation, start by determining the required conveyor belt speed, calculate the driven sprocket RPM from belt speed and sprocket diameter, then work backward through the gear ratio to select the drive sprocket tooth count within the No.80-3 American Sprocket range. Minimum recommended tooth count for the smaller sprocket is Z=17 to avoid excessive polygonal velocity ripple at typical industrial conveyor speeds.<\/div>\n<\/details>\n<\/div>\n

The EP-\u23000.625″ is catalogued as No.80-3 within the American Sprockets Series \u2014 a triple-strand (triplex) steel stock sprocket conforming to ANSI B29.1 and the broader American standard chain sprocket system. The No.80 chain designation specifies a 1-inch pitch and a 0.625-inch (5\/8″) roller diameter, placing this size in the medium-heavy duty segment of American metric sprockets and industrial roller chain drives.<\/p>\n

The dimensional framework follows ANSI\/ASME B29.1 precisely. The simplex tooth width b1 is 0.557 inches, expanding to 1.710 inches for the duplex tooth width B2 and 2.863 inches for the triplex tooth width B3. These three widths accommodate the three-strand chain’s inner and outer plate stack while maintaining the correct lateral clearance for smooth, low-wear roller engagement across all three strands simultaneously.<\/p>\n

The tooth count range \u2014 11 through 95 \u2014 gives procurement engineers a wide selection of gear ratios within a single catalogue series. American sprockets sizes from Z=11 with a 4.010-inch outer diameter up to Z=95 with a 30.830-inch outer diameter cover an exceptional span, from compact high-speed pinion positions to large, slow-speed elevator and conveyor driven sprockets. Material throughout is carbon steel with induction-hardened tooth flanks, meeting the quality levels that ANSI B29.1-conformant industrial sprockets and gears require for rated service life in medium-heavy duty applications.<\/p>","protected":false},"featured_media":256,"template":"","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":""},"product_brand":[],"product_cat":[19],"product_tag":[],"class_list":["post-255","product","type-product","status-publish","has-post-thumbnail","product_cat-american-standard-sprockets","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/kettenrad-zahnrader.com\/kk\/wp-json\/wp\/v2\/product\/255","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/kettenrad-zahnrader.com\/kk\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/kettenrad-zahnrader.com\/kk\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/kettenrad-zahnrader.com\/kk\/wp-json\/wp\/v2\/media\/256"}],"wp:attachment":[{"href":"https:\/\/kettenrad-zahnrader.com\/kk\/wp-json\/wp\/v2\/media?parent=255"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/kettenrad-zahnrader.com\/kk\/wp-json\/wp\/v2\/product_brand?post=255"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/kettenrad-zahnrader.com\/kk\/wp-json\/wp\/v2\/product_cat?post=255"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/kettenrad-zahnrader.com\/kk\/wp-json\/wp\/v2\/product_tag?post=255"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
