Dual-Standard DIN 8187 & ISO/R 606 Compliance

Full conformance with both DIN 8187 and ISO/R 606 makes the 05B-1-2 sprocket genuinely interchangeable with parts sourced from European and Asian OEMs. On UK production lines where German packaging machinery sits alongside Japanese automation equipment, this dual standard compliance eliminates compatibility uncertainty during planned maintenance windows and unplanned breakdowns alike. Procurement teams can approve a single part number across multiple machine platforms, reducing stock complexity and simplifying re-order workflows for maintenance stores managers across British industrial sites.

C45 Steel Construction with Induction-Hardened Flanks

C45 medium-carbon steel provides the ideal balance between machinability and response to localised heat treatment. Once the tooth profiles are precision-hobbed to DIN tolerances, selective induction hardening at the flank surfaces raises surface hardness well above that of untreated mild steel while keeping the core tough and crack-resistant under shock loading. This construction approach delivers longer service intervals on continuous-duty conveyor systems and stop-start indexing drives, reducing both the frequency of replacement and the associated maintenance labour costs for UK plant engineering teams operating on tight maintenance budgets.

Simplex & Duplex in a Single Product Family

Covering both simplex and duplex strand configurations within a single product series means design engineers can select the appropriate drive strand count without switching to a different pitch or sourcing from a separate product line. Simplex variants provide clean, economical drives for moderate-torque applications; duplex configurations double the load-carrying capacity within the same pitch diameter, a practical solution for compact conveyor assemblies in the North West of England where minimising shaft centre distance is a mechanical design priority without downrating the drive power.

Weld-On Hub Option for Custom Shaft Fitments

The weld-on hub option on larger Z-count 05B-1-2 sprockets gives fabricators and OEM builders the freedom to machine a custom hub to any required bore, key, and shoulder geometry, then weld it directly to the sprocket body for a permanent, precision-concentric fitment. This is particularly valuable on retrofit projects involving non-standard drive shafts — a scenario that arises regularly in older UK food and beverage processing lines being upgraded for higher throughput — where standard keyway bores do not match the existing shaft sizes and bespoke castings carry unacceptable lead times and cost premiums.

Z=8 to Z=125: Over Fifty Tooth Counts from Stock

With more than fifty individual tooth counts available across the Z=8–125 range, drive system designers can hit virtually any required speed ratio using catalogue stock items rather than waiting weeks for custom-cut sprockets. Popular sizes are held in finished inventory for fast despatch to buyers throughout England, Scotland, and Wales. For maintenance engineers at East Midlands automotive plants and South East logistics centres operating to strict just-in-time schedules, this stock depth translates directly into predictable planned-maintenance windows and dramatically lower emergency downtime costs.

Fast UK Despatch & Full Technical Support

Stock 05B-1-2 sprockets are available for same-week despatch across mainland Great Britain. Every order is supported by dimensionally verified inspection records, material test certificates to BS EN 10204 3.1 where required, and post-delivery application engineering assistance. Whether you are a machine builder in Scotland placing a first-off order or a group procurement manager in the South East raising a blanket release, our B2B team provides the documentation and responsiveness that industrial buyers in the UK expect from a specialist chain drive component supplier.

Production of the 05B-1-2 sprocket begins with C45 round bar cut to a length that provides sufficient stock allowance for facing, turning, and bore operations on a CNC lathe. The tooth profile is generated by gear hobbing to DIN 8187 tolerances, producing the involute tooth form that ensures smooth, progressive engagement of each chain roller through the pitch cycle and distributes load evenly across all engaged teeth — the primary factor in minimising vibration and noise on high-speed indexing drives used in packaging machinery and pharmaceutical tablet presses across the United Kingdom. Post-hobbing, tooth flanks are selectively induction-hardened before a final finish bore, face, and keyway broach where applicable. Each sprocket receives dimensional inspection against the published reference table prior to despatch.

Standard components are supplied with a light rust-preventive oil film adequate for twelve months of covered storage in typical UK warehouse conditions. For applications in British food manufacturing, whisky bottling, or pharmaceutical environments where hygiene standards or periodic wash-down procedures create a corrosion risk, zinc phosphate primer or electroless nickel plating are offered as optional surface treatments. Oil bath or grease lubrication of the chain-sprocket interface is recommended for operating speeds above 200 RPM; enclosed oil-splash arrangements extend service life further on continuous-duty drives running at higher speeds, particularly in printing line and textile machinery applications common across Yorkshire and Lancashire.

Chain Interface & General Data

* Weld-on hub applied on larger Z sizes (Z ≥ 78)

“We’ve been specifying the 05B-1-2 sprocket for our packaging line rebuilds for over three years. The DIN 8187 compliance gives our design engineers the confidence they need, and the stock availability means we’re never left waiting on a critical path item. The weld-on hub option on the larger sizes has saved us hours of custom machining time on retrofit projects.”

“Sourcing 8mm pitch sprockets to a verified standard had been a recurring headache for our maintenance team. Since switching to these for our food conveyor chain drives, the fit-for-purpose quality has been consistent across every delivery. We’ve even used the simplex and duplex variants on the same production line without issue. Excellent technical support when we needed help specifying the correct tooth count for a gearbox ratio change.”

“We needed a sprocket supplier for a prototype agricultural handling system with a tight project timeline. The team turned around a quotation within four hours, confirmed DIN compliance and provided the full dimensional data we needed for our CAD model. Parts arrived in Bristol within two working days. Dimensionally spot-on and very well finished. We’ve now placed a blanket order for the production run.”
