The S9118A-T6028-42 is a double-ended, inline miniature spur gearhead with a 1.75" O.D. (Bu-Ord size 18) and a reduction ratio of 1183 to 1. It features ball bearings throughout, a maximum starting torque of 0.02 ozf-in, and a rated output torque of 54 ozf-in. Mounting dimensions are identical to Bu-Ord OP 1755 motor dimensions, and it uses a versatile clamp for secure attachment to servomotors without modifications. The output rotation direction is opposite to the input, as indicated by the "R" designation. Zero-backlash, low-backlash, and exact-ratio 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”.
