The S991LYM10B is a heavy-duty 'L' gear drive with a 2:1 ratio, designed for low noise and high efficiency. It features spiral bevel gears made of case-hardened alloy steel and an aluminum die-cast housing, with alloy steel shafts. The unit has a 10 mm output shaft diameter, operates at speeds up to 3600 RPM, and has an operating temperature range of -10°C to +40°C. Its dimensions are 37 mm (A) by 58 mm (B) by 82 mm (L), and it weighs 0.4 kg. Backlash ranges from 30' to 1°23'. The drive is reversible and maintenance-free, with a flat keyway on the output shaft. All dimensions and ratings are consistent with the S991LYM10 series.
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”.
