The S9115A-T6023 is a double-ended, inline miniature speed reducer with a 1.4375-inch outer diameter, designed for Bu-Ord frame size 15 servomotors. It features ball bearings throughout, a maximum backlash of 0° 30', a rated output torque of 40 ozf·in, and a maximum starting torque of 0.01 ozf·in. Mounting dimensions match Bu-Ord OP 1755 motor specifications. The unit has a 122.83:1 reduction ratio and output rotation opposite to input rotation. Zero-backlash and low-backlash variants are available on special order.
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”.
