SDP/SI supplies precision planetary gearheads for high torque applications and inline spur gearheads featuring anti-backlash design.

Our high performing planetary gearhead, PAC series, is offered as an inline configuration with a caged planet carrier, in ratios of 3 – 100:1. The PAC series is a highly efficient unit operating quietly at 61 dBA/1m.

The SDP/SI precision MGX spur gearheads and speed reducers are designed, manufactured, and assembled in our state-of-the-art manufacturing facility. The unique gear train design is available in a wide range of ratios from 5:1 thru 1521:1. Designed and manufactured to the most stringent requirements set forth by the US Navy Bureau of Ordnance (Bu-Ord), for applications in surface, underwater, aviation fire control, and computing and navigational systems, as well as missiles.

SDP/SI planetary and spur gearheads provide multiple advantages beyond speed reduction:

  • Maximize your motor power/speed operation.
  • High rated torque in very compact design.
  • Extensive selection of gear ratios from 3:1 to 1092:1.
  • Orientation independent allow to be mounted in any space
  • In-line design and is reflected back to the motor with matching inertia for increased stability and smooth motion control.
  • Custom design size, gear ratio, and backlash available to meet specific needs, available on request.
