R series - Worm gear units

  • Power range: 0.12–7.5kW
  • Ratio: 7.1–63 (imax: 2500)
  • Torque: 36–553 N.m


Unique modular design, general applications of components are maximized, which is convenient for international production, storage quantity is small, supplement circle is short.Unique modular design, allocation exchange degree of functional attachments flexibly satisfies various kinds of required structures, arrangement form and different working situations of customer equipment.
Homodromous shaft output, worm box can be used together, thus reduce driving source.
Optimized worm gear contact pattern. The transmission accuracy is high, bearing capacity is large.
It can get large transmission ratio with single level transmission, the transmission is stable, it owns foot mounting, flange mount, shaft mount, shaft mounting and various kinds of mounting methods.
Vibration, impact and noise are low.
It owns foot mounting, flange mounting, shaft mounting and various kinds of mounting methods, which can satisfy various kinds of mounting requirements of customers.
