Speed reducers

AD reducers offer backlash as low as 3 arc-min and high shock load capacity in an interchangeable design.

Features & benefits

  • Input speeds to 6,000 rpm; output peak torque from 40 to 384 Nm (one-stage) and 38 to 4,000 Nm (two-stage)
  • Slotted interface allows quick and easy installation with any servomotor
  • Steel, aluminum, or stainless-steel housing
  • Contact of three planetary gears in steel crown gear with large diameter output provides high torsional stiffness
  • Two output bearings result in higher bearing capacity and long life
