FAQ

Common questions about this series

Hub Sprockets: what size range does the table cover?

The table lists 333 standard sprockets for 10 chain sizes (05B / 06B / 081 / 083 / 08B / 10B / 12B / 16B / 20B / 24B), 8–57 teeth, in single, double and triple strand versions. Bores, keyways and set-screw holes are machined to your drawing; other tooth counts and chain sizes are made to order.

Hub Sprockets: what is it and when should I use it?

Hub sprockets with a boss — the hub takes bores, keyways and set screws; rigid and shaft-ready. Made to GB/T 1243 / ISO 606 / DIN 8187 tooth forms, teeth can be induction hardened. The table lists teeth z, OD de, pitch dia. dp and hub dimensions for single / double / triple rows by chain number. Hub sprockets take bores, keyways and set screws directly and are the shaft-ready default; plate sprockets are the light, economical option to weld or bolt onto a hub or flange; taper-bushed sprockets mount keyless with a Taper-Lock bush for quick, well-centred fitting and removal. Tooth forms follow GB/T 1243 / ISO 606 / DIN 8187 and teeth can be induction hardened.

Hub Sprockets: can I order a size that is not in the table, or just one piece?

Yes. Everything on this page is made to drawing, and the table is only the standard-size subset of the catalogue. Minimum order quantity is one piece — we routinely make single replacement parts for OEMs whose original supplier has discontinued the item. Send a DWG, STEP or PDF drawing (or a sample part): you get a formal quotation within 24 hours after the information is complete, and the first article ships within 30 days of drawing approval, with inspection records.

Hub Sprockets: what do I need to send to get a quote?

Send the drawing or: chain size (ANSI/ISO number or pitch), number of teeth, strands, hub type (A/B/C/D) and dimensions, bore with tolerance and keyway, set-screw holes, hardening requirement and quantity. For a non-standard chain, send the chain spec sheet or the chain itself.
