The S9111A-T6017-45 is a double-ended, inline miniature speed reducer with a 1.0625-inch outer diameter, designed for Bu-Ord size 11 servomotors and compatible with mounting dimensions specified in Bu-Ord OP 1755. It features a zero-backlash gear train with ball bearings throughout and a maximum backlash of 30 arc minutes. The unit provides a reduction ratio of 273.71:1, 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 the gears are made of hardened 416 stainless steel with aluminum bronze stages. The output shaft orientation is in-line, and the reducer is available in both low- and zero-backlash configurations.
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”.
