The S9111A-T6017 series is a double-ended, inline miniature speed reducer with a 1.0625 in. O.D. designed for Bu-Ord size 11 servomotors, matching mounting dimensions to Bu-Ord OP 1755. It features zero-backlash capability, ball bearings throughout, and a maximum integrated position error of 15 arc minutes for the zero-backlash variant. The model S9111A-T6017-69 provides a reduction ratio of 1267.69:1, with a rated output torque of 30 ozf·in. and a maximum starting torque of 0.01 ozf·in. The housing is black-anodized aluminum, and all gears and pinions are made of hardened 416 stainless steel. The input and output shafts are coaxially extended, enabling flexible mounting. Zero-backlash, low-backlash, and exact ratio configurations 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”.
