The S9118A-T6028 series is a double-ended, inline miniature spur gearhead designed for Bu-Ord size 18 servomotors with a 1.75 in. outer diameter. It features ball bearings throughout, and the mounting dimensions are identical to Bu-Ord OP 1755 motor specifications. The model S9118A-T6028-44 provides a reduction ratio of 1521:1 with output rotation opposite to the input, and has a rated output torque of 54 ozf·in. Maximum backlash is 0° 30'. Low-backlash, zero-backlash, and exact-ratio versions 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”.
