The S9111A-T6019 is a double-ended, inline miniature speed reducer with a 1.0625-inch outer diameter, designed for Bu-Ord size 11 servomotors. It features zero-backlash gearing using a torsion spring mechanism to eliminate lost motion throughout the gear train. The unit has a maximum backlash of 0° 30', a rated output torque of 30 ozf-in, and is equipped with ball bearings throughout. Mounting dimensions are identical to Bu-Ord OP 1755 motor specifications, allowing direct attachment without adapters. The input and output shafts are coaxial, and the design permits mounting on either end.
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”.
