The EP 08B-1-2-3 series is one of the most versatile entries in the European Standard Sprockets Series: a single 1\/2″\u00d75\/16″ European Sprocket family that covers simplex, duplex, and triplex chain configurations within one documented product range. With a 12.7 mm chain pitch, 7.75 mm internal width, and 8.51 mm roller diameter, each unit in this series is manufactured in full compliance with DIN 8187 and ISO\/R 606 \u2014 the foundational standards for European roller chain drives. The triplex capability sets the 08B-1-2-3 apart from most other families in the 1\/2″ pitch class: three parallel chain strands on a single sprocket hub triple the torque capacity of the drive without requiring a larger chain pitch or a complete drive system redesign.<\/p>\n

Tooth counts run from Z=8 through Z=125, giving transmission engineers access to ratio spans from near 1:1 to greater than 15:1. The 5\/16″ inner width (7.75 mm) \u2014 wider than both the 1\/8″ and 1\/4″ variants in the 1\/2″ pitch family \u2014 accommodates heavier chain side plates that resist lateral deflection under dynamic loads. For engineering teams in Germany, Spain, Colombia, and other markets where DIN 8187 documentation is the procurement baseline, this product range delivers dimensional traceability, structural flexibility, and stock availability from a single qualified European Sprocket Manufacturer.<\/p>\n

3. Five Key Advantages of 08B-1-2-3 European Sprocket<\/h2>\n
\n
\n
\u2713 Simplex, Duplex, and Triplex in One Family<\/div>\n

The defining characteristic of the 08B-1-2-3 European Sprocket range is its three-strand scope. A machine designer starting with a simplex European Sprocket at Z=20 can escalate to a duplex or triplex configuration on the same shaft \u2014 same tooth count, same pitch circle, same shaft centres \u2014 by adding chain strands and fitting the wider hub variant. This scalability means that as load requirements grow over a machine’s commercial life, the drive architecture remains unchanged: no new gearbox sizing, no shaft centre recalculation, no housing modification. For industrial machinery built on tight cost budgets in Colombia or Germany, that forward-compatibility has real commercial value.<\/p>\n<\/div>\n

\n
\u2713 Full DIN 8187 \/ ISO\/R 606 Traceability<\/div>\n

Every European Sprocket in the 08B-1-2-3 series is produced and verified against DIN 8187 and ISO\/R 606. These are not self-certified claims: tooth radius r\u2083 = 13 mm, radius width C = 1.3 mm, and strand widths B\u2081 = 7.2 mm, B\u2082 = 21 mm, and B\u2083 = 34.9 mm are all values specified in the normative documents, measurable with calibrated instruments, and reportable in dimensional inspection certificates. For procurement teams in Germany sourcing a replacement kettenrad zahnrader or specifying new industrial drives, and for Colombian buyers needing standards-referenced documentation for DIAN import clearance, this DIN\/ISO traceability simplifies both incoming inspection and cross-border documentation.<\/p>\n<\/div>\n

\n
\u2713 5\/16″ Inner Width for Heavy Chain Side Plates<\/div>\n

The 7.75 mm inner width of the 08B-1-2-3 European Sprocket is the widest inner-width specification in the 1\/2″ pitch family documented here. Wider inner width means wider, heavier chain side plates, which in turn provide greater lateral bending stiffness. For a European Sprocket drive subject to variable load impulses \u2014 such as agricultural equipment traversing uneven terrain in Colombia’s coffee and sugar-cane growing regions, or industrial conveyors in German facilities where product loading is irregular \u2014 the heavier side plate of the 5\/16″ chain reduces the risk of chain whip, lateral fatigue cracking, and premature chain elongation compared to the narrower 1\/8″ and 1\/4″ inner-width variants.<\/p>\n<\/div>\n

\n
\u2713 Transparent Weld-On Hub Transitions<\/div>\n

The dimensional table marks the transition from stock bore to weld-on hub construction: Z=41 for simplex (*90), Z=43 for duplex and triplex variants (*108 and *120). This documentation transparency prevents specification errors at the drawing stage. Engineers planning drive housings for large-diameter installations can account for the weld-on hub geometry \u2014 specifically the increased hub outer diameter that affects housing clearance \u2014 before tooling or fabrication begins, rather than discovering the constraint at assembly. This level of structural disclosure is consistent with the documentation standards expected from a qualified European Sprocket Manufacturer.<\/p>\n<\/div>\n

\n
\u2713 CNC-Quality Tooth Profiles Across Z=8 to Z=125<\/div>\n

Producing a consistent r\u2083 = 13 mm tooth radius across tooth counts from Z=8 to Z=125 \u2014 and across three strand-width configurations \u2014 requires CNC machining rather than conventional hobbing alone. Our European Sprocket production uses CNC centres that hold tooth profile tolerances to DIN quality grade levels on every batch, not just on qualification runs. The result is predictable roller engagement noise, uniform tooth wear distribution, and a service life that matches the dimensional accuracy implied by the DIN 8187 specification. For industrial sprockets and gears operating in continuous-shift production environments in Colombia and Europe, this consistency reduces unplanned maintenance stoppages and extends the interval between European Sprocket replacement cycles.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

4. How the 08B-1-2-3 European Sprocket Works<\/h2>\n

A European Sprocket is a positive-engagement power transmission element: unlike a friction pulley, it transfers torque through direct mechanical contact between each tooth and the corresponding chain roller. As the drive shaft rotates the input sprocket, teeth push the rollers forward sequentially, pulling the chain and driving the output shaft. Because engagement is positive, there is no slip, and the transmitted torque is governed only by the chain’s rated tensile strength and tooth geometry \u2014 not by friction coefficient or surface condition. This is why sprockets and chains remain the preferred transmission choice in agricultural, conveyor, and industrial machinery where exact speed ratios must be maintained regardless of load variation.<\/p>\n

In this series, tooth radius r\u2083 = 13 mm is the primary engagement geometry parameter. It is calculated to match the 8.51 mm roller diameter of the 08B chain: as the roller enters the tooth pocket from the approaching chain side, it rides along the tooth flank arc of 13 mm radius, seating at the pitch circle at the base of the tooth valley. Radius width C = 1.3 mm provides a flat relief at the tooth tip to prevent roller contact during chain articulation. The 1.3 mm C value in this European Sprocket is slightly wider than the 1.0 mm used in the 05B and 081B families \u2014 reflecting the larger roller diameter and the correspondingly greater geometric demands at the tooth tip.<\/p>\n

The strand configurations \u2014 simplex (B\u2081 = 7.2 mm), duplex (B\u2082 = 21 mm), and triplex (B\u2083 = 34.9 mm) \u2014 represent increasing multiples of the single-strand width, with inter-strand gaps sized to the chain manufacturer’s plate clearance specification. Each chain strand on a multi-strand European Sprocket carries an equal share of the total drive tension when the European Sprocket hub and shaft are correctly aligned, making load distribution inherently balanced in a well-installed triplex drive. The hub A dimension grows progressively from simplex through triplex for any given tooth count; weld-on hub construction begins at Z=41 (*90 simplex) and Z=43 (*108\/*120 duplex\/triplex), where through-bored blanks can no longer provide the hub wall thickness needed for multi-strand chain tension at large diameters.<\/p>\n<\/div>\n

<\/p>\n

\n

5. Material and Surface Treatment<\/h2>\n

C45 medium-carbon steel is the standard production material for the 08B-1-2-3 European Sprocket series, as specified in the product documentation. C45 is selected for its machinability and heat-treatability: induction hardening elevates tooth flank surface hardness to 50\u201358 HRC while leaving the hub core in tougher normalised condition. This hardness gradient is the correct approach for any roller chain sprocket that must resist both surface abrasive wear at the tooth flanks and impact shock loading (from sudden load application or start-stop cycling in agricultural and conveyor machinery). A fully hardened European Sprocket hub would be brittle under shock; a fully soft one would wear prematurely at the tooth contact surfaces.<\/p>\n

For European Sprocket installations in environments where corrosion is a design concern \u2014 food and beverage production lines in Colombia subject to wash-down, outdoor agricultural drives in humid tropical climates, or chemical handling conveyors \u2014 stainless steel sprockets & gears in AISI 304 or AISI 316L are available as alternative material specifications. AISI 316L provides superior chloride resistance over 304, making it the preferred material for wash-down zones using hypochlorite or peracetic acid cleaning agents. Material test certificates for stainless variants include chemical composition and mechanical properties of the production heat, supporting material traceability requirements under hygiene compliance audits in Colombia and EU food production regulations.<\/p>\n

Black oxide treatment on standard C45 European Sprocket blanks produces a black kettenrad zahnrader finish \u2014 visually distinctive and carrying a mild corrosion deterrent for low-humidity indoor storage and operation. Zinc phosphate and electroless nickel plating are available as further options, each with different performance characteristics in corrosion resistance and dimensional effect. Plastic sprockets and gears in POM or PA66 are produced for specific light-duty European Sprocket applications where noise reduction, weight minimisation, or metal-free operation in the drive zone are design requirements, though load and temperature ratings for polymer variants are significantly lower than for steel. All surface treatment options for this series are RoHS-compliant and SVHC-declarable on request.<\/p>\n

6. Application Scenarios<\/h2>\n

The 08B-1-2-3 is specified wherever the drive requires more torque capacity than a narrow 1\/2″ chain can provide, but a change to a larger chain pitch would be mechanically disproportionate or commercially inconvenient. The triplex European Sprocket option in particular opens application territory that most 1\/2″ pitch sprocket families cannot reach without moving to a completely different chain standard.<\/p>\n

\n
\n
\u2699 Agricultural Machinery \u2014 PTO and Field Drives<\/div>\n

Combine harvester grain elevators, forage harvester chopping heads, sugar cane cutting machinery, and PTO-driven field implements across Colombian and European agricultural operations frequently use 1\/2″\u00d75\/16″ chain drives for main power transmission stages. The range covers both simplex drives on lighter implements and duplex drives on heavier multi-section harvesters, while the triplex European Sprocket variant handles the highest-torque agricultural applications \u2014 such as the main chain stage of a large-capacity forage wagon \u2014 without switching to the 16A or 20A heavy pitch families. This pitch versatility reduces the number of distinct chain standards a service workshop needs to carry for agricultural replacement kettenrad zahnrader stock.<\/p>\n<\/div>\n

\n
\u2699 Industrial Conveyors and Material Handling<\/div>\n

Overhead power-and-free conveyors, pallet accumulation systems, and heavy roller conveyors in automotive and general manufacturing plants specify industrial sprockets and gears in the 5\/16″ inner width class where the chain strand must carry both axial tension and the lateral loading of off-centre products or directional changes. Duplex and triplex configurations are common specifications for head-drive drums and return stations, where doubling or tripling the strand count reduces the load per link \u2014 extending both chain and European Sprocket service life without a drive redesign. German automotive facility conveyor specifications frequently reference this European Sprocket format.<\/p>\n<\/div>\n

\u2699 Food and Beverage Processing<\/div>\n

Bottling line conveyors, can-handling systems, tray sealers, and pasteurisation line transport drives in food and beverage facilities use 08B chain drives with stainless steel European Sprocket components in wash-down zones where regular chemical cleaning is routine. In Colombian food manufacturing \u2014 particularly in the processing of fresh flowers, coffee, and tropical fruit for export markets \u2014 stainless steel sprockets & gears conforming to DIN 8187 are increasingly specified to satisfy the European import partner’s machinery documentation expectations. A duplex unit at mid-tooth counts provides the torque headroom for heavily loaded bottle conveyors without requiring a larger pitch chain that would not fit in existing machine housings.<\/p>\n<\/div>\n

\n
\u2699 Mining, Quarrying and Construction Equipment<\/div>\n

Aggregate sorting screens, stone crusher feed conveyors, and underground material haulage auxiliary drives encounter sustained high-torque loads that push single-strand chain drives to their limits. The triplex European Sprocket \u2014 with weld-on hub construction from Z=43 upward \u2014 is a practical specification for these applications: three parallel chain strands on a single European Sprocket hub provide the combined tensile capacity needed without stepping to the heavier 16A or 20A pitch chains. For mining operators in Colombia’s coal and mineral extraction regions, where spare parts logistics favour common component standards, the DIN 8187 traceability of this European Sprocket simplifies cross-border procurement from European suppliers.<\/p>\n<\/div>\n

\n
\u2699 Packaging and Printing Machinery<\/div>\n

High-speed cartoning, shrink-wrapping, and letterpress printing machinery use chain drives with chain gears and sprockets in the 1\/2″ pitch range for synchronisation of multi-station production lines. The 08B-1-2-3 European Sprocket in simplex configuration covers the lighter drive stages where B\u2081 = 7.2 mm tooth width is appropriate; duplex European Sprocket variants handle the main drive stages on large-format packaging lines where torque from multiple section drives accumulates. Print registration drives in commercial printing plants across Colombia and Spain specify best european sprockets in this pitch class where consistent tooth pitch geometry governs print-to-print accuracy across long production runs.<\/p>\n<\/div>\n

\n
\u2699 Textile and Garment Manufacturing<\/div>\n

Weaving looms, knitting machines, and garment production conveyors in Colombia’s significant textile manufacturing sector use European Sprocket drives in the 1\/2″ pitch class for pattern indexing, fabric advance mechanisms, and overhead transport. The controlled tooth geometry and 7.75 mm inner width of the 08B-1-2-3 European Sprocket ensures consistent chain speed at the moderate drive speeds typical of textile machinery \u2014 avoiding the chordal speed variation that causes fabric pickup irregularities on looms. The compact tip circle diameter at low tooth counts (Z=8, d\u2083 = 37.2 mm) allows the European Sprocket to fit within the tight space constraints common in textile machine frames.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

7. Regional Standards and Regulatory Context<\/h2>\n

Specifying a European Sprocket for cross-border machinery projects requires understanding how DIN 8187 and ISO\/R 606 standards connect with each target market’s regulatory and documentation framework.<\/p>\n

\n
\n

EU \u2014 Machinery Regulation (EU) 2023\/1230<\/strong><\/p>\n

The CE Technical File for machinery incorporating an 08B European Sprocket should reference DIN 8187 \/ ISO\/R 606 as the harmonised component standard. Machinery Regulation (EU) 2023\/1230 \u2014 entering full application in 2027 \u2014 maintains this approach. A European Sprocket does not individually require CE marking; it is covered by the machine-level declaration. Dimensional conformity documentation for the European Sprocket supports the Technical File risk assessment without additional certification burden.<\/p>\n<\/div>\n

\n

Germany \u2014 DIN 8187 and DIN 8181<\/strong><\/p>\n

Sprockets germany procurement defaults to DIN 8187 for roller chain sprockets and DIN 8181 for precision short-pitch chains. A new kettenrad zahnrader or replacement kettenrad zahnrader in German machinery must conform to these norms. Our 08B-1-2-3 European Sprocket is fully documented to DIN 8187, with inspection records available at order placement for supplier qualification audits. The size kettenrad zahnrader enquiry process for this European Sprocket family is straightforward \u2014 provide tooth count, strand count, and bore requirement.<\/p>\n<\/div>\n

\n

Colombia \u2014 ICONTEC, DIAN, INVIMA and RETIE<\/strong><\/p>\n

Colombian import of this European Sprocket falls under DIAN HS code 8483.40.90. Food-contact applications in Colombia require INVIMA-compatible material documentation \u2014 available for stainless steel European Sprocket variants. Electrically actuated drives incorporating the European Sprocket must comply with RETIE electrical safety regulations. ICA phytosanitary records apply for agricultural machinery imports. ICONTEC’s adoption of ISO 606 as the Colombian chain component standard aligns directly with the ISO\/R 606 basis of this European Sprocket series.<\/p>\n<\/div>\n

\n

UK \u2014 UKCA and BS EN ISO 606<\/strong><\/p>\n

Post-Brexit UK machinery requires UKCA marking based on BS EN ISO 606, the British transposition of ISO 606 \u2014 which is dimensionally harmonised with DIN 8187. The 08B-1-2-3 European Sprocket conformity documentation is compatible with UKCA Technical File requirements. UK machinery OEMs sourcing this European Sprocket for dual EU\/UK machines can use the same conformity records for both CE and UKCA audit purposes.<\/p>\n<\/div>\n

\n

USA \u2014 ANSI #40 \/ #41 Distinction<\/strong><\/p>\n

The 08B European Sprocket at 12.7 mm pitch has the same pitch number as ANSI #40 \/ #41 chain, but both inner widths and roller diameters differ: 08B uses 7.75 mm inner width and 8.51 mm roller; ANSI #40 uses 7.94 mm inner width and 7.92 mm roller. These are not interchangeable. US buyers should verify DIN 8187 compliance explicitly when importing this European Sprocket for machinery exported to European or Latin American markets.<\/p>\n<\/div>\n

\n

EU Environmental \u2014 RoHS and REACH<\/strong><\/p>\n

Surface treatments on steel sprockets and gears \u2014 including zinc phosphate and black oxide applied to this European Sprocket \u2014 must comply with EU RoHS Directive 2011\/65\/EU and REACH Regulation EC 1907\/2006 for EU-market machinery. Our European Sprocket surface treatment processes are fully RoHS-compliant, with SVHC substance declarations available in the compliance documentation upon request.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Roller Chain \u2014 Matched to 08B European Sprocket<\/h3>\n

Each configuration of the 08B-1-2-3 European Sprocket requires a specifically dimensioned chain: 12.7 mm pitch, 7.75 mm inner width, 8.51 mm roller diameter, conforming to DIN 8187. The simplex configuration runs one strand; duplex and triplex run two and three parallel strands of the same chain respectively. Purchasing sprockets and chains<\/a> from a single verified supply source eliminates the specification inconsistencies that arise when components come from manufacturers who interpret the same ISO standard slightly differently.<\/p>\n

NMRV Worm Reducers \u2014 Speed Matching Input Stage<\/h3>\n

Where a motor must be speed-reduced before driving the 08B-1-2-3 European Sprocket chain stage, NMRV worm gear reducers provide compact right-angle reduction at ratios from 5:1 to 100:1. The output shaft bore range of standard NMRV reducers aligns with the stock-bore range of the 08B-1-2-3 European Sprocket at typical low-to-mid tooth counts, making shaft-to-sprocket installation straightforward without custom adapters in most standard configurations. This integrated supply \u2014 NMRV reducer coupled directly to the sprocket drive stage \u2014 is a practical one-stop solution for conveyor heads, agitator drives, and main drive stages on packaging machines across European and Colombian industrial facilities.<\/p>\n

\nQ1. What is a triplex European Sprocket, and when should I specify the 08B-1-2-3 triplex configuration for a Colombian industrial conveyor?<\/summary>\n

A triplex European Sprocket carries three parallel strands of chain side by side on a single hub, tripling the torque capacity of the drive compared to a simplex European Sprocket of the same tooth count. Specify the 08B triplex configuration when drive torque exceeds the single-strand capacity of the 08B chain, but you want to avoid upgrading to a heavier pitch chain (which would require redesigning shaft centres, housings, and guards). The triplex European Sprocket provides the torque headroom while keeping the 12.7 mm pitch chain standard unchanged across the installation.<\/p>\n<\/details>\n

\nQ2. What is the difference between the 08B European Sprocket and the 081B European Sprocket, and how do I know which one my existing drive uses?<\/summary>\n

The 08B series has a 7.75 mm inner chain width; the 081B has 3.3 mm. Both use 12.7 mm pitch, but the 08B has a wider chain with a larger roller (8.51 mm vs 7.75 mm) and significantly wider tooth faces \u2014 B\u2081 = 7.2 mm versus 3.0 mm. To identify your existing European Sprocket, measure the inner chain width between the side plates at any link pin. The tooth face width is also a quick field check: you can visually see whether the sprocket face is closer to 7 mm or 3 mm wide. Do not use 08B chain on a sprocket designed for 081B chain, or vice versa.<\/p>\n<\/details>\n

\nQ3. Which material should I specify for an 08B European Sprocket on a food processing conveyor in Colombia that uses regular chemical cleaning?<\/summary>\n

For Colombian food processing conveyors with regular chemical wash-down \u2014 particularly using chlorinated cleaning agents \u2014 specify AISI 316L stainless steel European Sprocket units. We supply 316L European Sprocket variants with material test certificates that satisfy INVIMA hygiene material audit requirements in Colombian food manufacturing. For light-duty food handling zones where metal contamination avoidance is a design requirement, plastic sprockets and gears in food-grade POM are available as an alternative to the steel European Sprocket for those specific sections of the conveyor.<\/p>\n<\/details>\n

\nQ4. What is the difference between gears and sprockets, and when should an engineer in Germany use a European Sprocket drive instead of a gear drive?<\/summary>\n

The difference between gears and sprockets lies in their transmission mechanism: gears mesh directly tooth-to-tooth at a fixed, close centre distance; a European Sprocket transmits through an intermediate chain that bridges much longer centre distances and can route flexibly around obstacles. In German industrial applications where the motor mounting position is dictated by an existing plant layout rather than transmission geometry \u2014 common in production hall retrofits \u2014 a sprocket-and-chain drive provides the layout flexibility that gear drives cannot. Ratio changes on a European Sprocket drive also require only sprocket replacement, not the machining of a new gear pair.<\/p>\n<\/details>\n

\nQ5. How do I calculate drive ratio and chain speed when specifying an 08B European Sprocket pair for a Colombian packaging machine running at 1,000 RPM?<\/summary>\n

Drive ratio = driven tooth count \/ drive tooth count. For a Z=15 drive and Z=45 driven European Sprocket the ratio is 3:1, giving 333 RPM output from 1,000 RPM. Chain speed (m\/s) = (Z \u00d7 pitch \u00d7 RPM) \/ 60,000. At Z=15, 12.7 mm pitch, 1,000 RPM: (15 \u00d7 12.7 \u00d7 1,000) \/ 60,000 = 3.18 m\/s \u2014 comfortably within the standard lubrication range for 08B. Our technical team can assist with centre-distance and chain length calculations at no charge for project enquiries.<\/p>\n<\/details>\n

\nQ6. Which european standard sprockets sizes in the 08B-1-2-3 range are stocked for immediate shipment to Germany without minimum order requirement?<\/summary>\n

Standard-stock European Sprocket sizes in the simplex 08B-1-2-3 range \u2014 typically Z=10 through Z=40 in common bore configurations \u2014 are available for same-week dispatch to Germany without minimum order quantity. Duplex and triplex European Sprocket sizes at commonly specified tooth counts are also held in stock. Weld-on hub European Sprocket units from Z=41 (simplex) and Z=43 (duplex\/triplex) upward are produced to order. For urgent new kettenrad zahnrader or replacement kettenrad zahnrader needs on any configuration, contact us with the tooth count and strand configuration and we confirm stock availability same-day.<\/p>\n<\/details>\n

\nQ7. What lubrication method is recommended for an 08B European Sprocket running at moderate speed on agricultural equipment in Colombia?<\/summary>\n

For agricultural European Sprocket drives at chain speeds up to approximately 4 m\/s in field conditions, manual drip or brush lubrication at scheduled service intervals is adequate in relatively clean environments. In dusty Colombian field conditions \u2014 common in dryland crop regions \u2014 shielding the chain and European Sprocket from airborne abrasive particles is as important as lubrication frequency: dust ingress accelerates tooth flank wear more rapidly than lubricant starvation. Sealed O-ring or X-ring chain variants retain factory lubricant inside the link joints and reduce field maintenance frequency significantly for remote-operation agricultural equipment.<\/p>\n<\/details>\n<\/div>\n<\/div>\n

\u0627\u0644\u0645\u062d\u0631\u0631: PXY<\/p>","protected":false},"excerpt":{"rendered":"

The 08B-1-2-3 designation signals three distinct strand configurations in a single product family. The “1” denotes simplex (single-strand), “2” duplex (two strands), and “3” triplex (three strands) \u2014 all sharing the same 12.7 mm pitch, 8.51 mm roller, and DIN 8187-specified tooth geometry.<\/p>\n

The 5\/16″ inner width (7.75 mm) that distinguishes this European Sprocket from the 1\/8″ and 1\/4″ variants in the same pitch class is not merely a dimensional difference \u2014 it implies a meaningfully heavier chain side plate. Wider side plates on the matched chain resist lateral bending and whip, which matters in drives with long unsupported chain spans, variable load, or shaft misalignment.<\/p>\n

The Z=8 to Z=125 tooth count range gives this European Sprocket family a ratio span from near 1:1 to over 15:1 within one chain standard. Weld-on hub construction begins at Z=41 for simplex (marked *90) and Z=43 for both duplex (marked *108) and triplex (marked *120), reflecting the structural reality that hub wall thickness requirements at large diameters exceed what a through-bored blank can sustain.<\/p>","protected":false},"featured_media":243,"template":"","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":""},"product_brand":[],"product_cat":[18],"product_tag":[],"class_list":["post-237","product","type-product","status-publish","has-post-thumbnail","product_cat-european-standard-sprockets","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/kettenrad-zahnrader.com\/ar\/wp-json\/wp\/v2\/product\/237","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/kettenrad-zahnrader.com\/ar\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/kettenrad-zahnrader.com\/ar\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/kettenrad-zahnrader.com\/ar\/wp-json\/wp\/v2\/media\/243"}],"wp:attachment":[{"href":"https:\/\/kettenrad-zahnrader.com\/ar\/wp-json\/wp\/v2\/media?parent=237"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/kettenrad-zahnrader.com\/ar\/wp-json\/wp\/v2\/product_brand?post=237"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/kettenrad-zahnrader.com\/ar\/wp-json\/wp\/v2\/product_cat?post=237"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/kettenrad-zahnrader.com\/ar\/wp-json\/wp\/v2\/product_tag?post=237"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
