The S9111A-T6017 is a double-ended, inline miniature speed reducer with a 1.0625 in. O.D., designed for Bu-Ord size 11 servomotors and mounted using the same clamp system as Bu-Ord OP 1755 motors. It features a zero-backlash or low-backlash design, has ball bearings throughout, and delivers a rated output torque of 30 ozf·in. The unit has a maximum backlash of 30 arc minutes in its standard configuration, and its input and output shafts are coaxial. The gearhead is built with hardened 416 stainless steel gears and aluminum bronze gear teeth for durability in demanding environments. Speed ratios are available in standard increments, including 185.94:1, as listed in the product tables. The housing is black-anodized aluminum, and the design meets MIL-STD-810 standards.
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”.
