The S9115A-T6023-08 is a 20.62:1 ratio, inline miniature double-ended speed reducer with a 1.4375-inch outer diameter, designed for use with Bu-Ord size 15 servomotors. It features a zero-backlash gear train with hardened 416 stainless steel gears and aluminum bronze pinions, stainless steel ball bearings throughout, and a black-anodized aluminum housing precision bored for exact center distances. The unit has a maximum backlash of 0° 30', a rated output torque of 40 ozf·in, and a maximum starting torque of 0.01 ozf·in. Output rotation direction matches input rotation, as indicated by the 'S' designation. Mounting dimensions align with Bu-Ord OP 1755 motor specifications, and it accepts the same mounting clamp used for MGX gearheads. All variants in the MGX T-Series use the same housing and mounting interface, with ratios and rotation direction being the primary differentiators.
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”.
