Selection guide
- Confirm the transmission type, load, speed and duty cycle.
- Choose model / module / pitch and the matching mating part (chain–sprocket, rack–pinion, belt–pulley, rail–block).
- Specify bore, keyway, length, material, heat treatment and surface finish.
- Send drawings or samples for non-standard parts; we confirm feasibility and quote.
