The A 2B 7-S035 is a 3.5:1 right-angle worm speed reducer with a compression-molded glass-fill polyester housing, sintered bronze bearings, and a ground steel worm driving a bronze gear. It has a solid input shaft and a solid output shaft with a 0.500-inch flat. The unit measures 3-3/8 inches high, 3-7/8 inches wide, and 3 inches deep, and weighs 28 ounces. It is rated for 1800 rpm input, delivering 514 rpm output and 102 lb-in torque, with a pre-lubricated grease system and sealed input shaft. The same housing, construction, and mounting dimensions apply across the 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”.
