The S9118A-T6028-31 is a double-ended, inline miniature spur gearhead with a 1.75" O.D. (Bu-Ord size 18) and a reduction ratio of 507:1. It has a rated output torque of 54 ozf-in and a maximum backlash of 0° 30'. Ball bearings are used throughout. Mounting dimensions conform to Bu-Ord OP 1755 motor specifications, allowing direct attachment to compatible servomotors using the supplied mounting clamp. The output rotates in the same direction as the input. 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”.
