Precision Gearheads & Gear Speed Reducers

  • Spur train and planetary gear trains ranging from size 5 (0.050” OD) to size 18 (1.75” OD)
  • Precision ball bearings used throughout. Lubricated per MIL-L-6085A
  • Rear bearing plate is positively positioned for perfect bearing alignment
  • Housing is integral part of precision gearhead, for lighter more rigid construction. No posts. More vibration and shock resistant
  • Unique cluster design includes gear & pinion hobbed from same centers providing greater concentricity and reduces total composite error

* Maximum Lost Motion: Measured at the output shaft with (*) inch ounce reversing load and a fixed dummy motor pinion engaged; fixture designed to introduce 70% of the maximum motor mounting errors.
