Structure & Feature Overview

helicalgear

High torque & low backlash

  • Helical gear type planetary gearing.
  • Improvement of wear resistance by gear heat treatment.
Planetary-Bearing

Increased service life

  • Full complement needle planet bearings. (Solid uncaged needle roller bearings)
Clamp-Ring

Dynamic balanced clamp ring mechanism

  • Error-Free installation and the balanced clamping system allows higher input speeds and no backlash for power transmission.
Motor-Flange

Universal mounting motor flange

  • Allows quicker delivery and easier mounting to any stepping motor and servo motor.
