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:
Notes:
1. Zero backlash available with anti-backlash option.
2. NEMA 17, 23, 42, and 56 interface available.
