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.
