FAQ

Common questions about this series

Taper Bushed Sprockets: what size range does the table cover?

The table lists 47 standard sprockets for 5 chain sizes (06B / 08B / 10B / 12B / 16B), 13–38 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.

Taper Bushed Sprockets: what is it and when should I use it?

Sprockets for Taper-Lock bushing mounting: keyless quick fitting, fast on/off, good centering — one body fits many shaft sizes. The table lists teeth, OD, pitch diameter, hub dimensions per row count and matching bushing numbers. 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.

Taper Bushed 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.

Taper Bushed 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.
