The S991TYM20A is a heavy-duty 'T' gear drive with a 1:1 ratio and a 20 mm shaft diameter, designed for low noise and high efficiency in applications requiring reversible operation and maintenance-free performance. It features spiral bevel gears made of case-hardened alloy steel and an aluminum die-cast case, with operating temperatures ranging from -10°C to +40°C. The unit measures 80 mm in length, 120 mm in width, and 36 mm in height, and weighs 3.4 kg. Shaft keyway dimensions are 6 mm wide, 6 mm deep, and 35 mm long. Backlash ranges from 8' to 33'.
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”.
