The S9111A-T6017 is a double-ended, inline miniature speed reducer with a 1.0625" O.D. designed for Bu-Ord size 11 servomotors, matching mounting dimensions to Bu-Ord OP 1755 motors. It features a zero-backlash gear train capable of delivering a rated output torque of 30 ozf-in with a maximum backlash of 0° 30'. Ball bearings are used throughout, and the unit supports ratios up to 714.69:1. The specific model S9111A-T6017-18 corresponds to a 46.59:1 reduction ratio. Low-backlash and zero-backlash variants are available, with all units accommodating direct motor attachment via a standard mounting clamp.
Speed reducers are components that use a gear train to reduce output rpms. MGX gearheads and speed reducers are made to the highest exacting standards of craftsmanship. Our MGX gearheads are attachable to the U.S. Bureau of Ordnance (Bu-Ord for short) frame-size servomotors without modifications to the input pinions and without complicated adapters, screw threads, etc., thanks to the versatile mounting clamps supplied. Mounting dimensions are identical to Bu-Ord OP 1755 motor dimensions.
Our speed reducers are offered in low and zero backlash options, with single- and double-ended shafts. They are available in Bu-Ord sizes 11, 15, and 18 and with an O.D. of 1-1/16”, 1-7/16”, and 1-3/4”.
