The A 2B 7-H300 is a 30:1 right-angle worm gear speed reducer with a compression-molded glass-fill polyester housing, sintered bronze bearings, and a ground steel worm driving a precision-hobbed bronze gear. It features a hollow output shaft with a 0.626 in. bore and 0.630 in. outer diameter, and a 0.875 in. input shaft diameter. Dimensions are 3-3/8 in. high, 3-7/8 in. wide, and 3 in. deep, with a weight of 28 oz. Rated for 1800 rpm input, it delivers 30 rpm output at 75 lb-in. torque. Input and output shafts are sealed and prelubricated with grease. The reducer is designed for commercial applications and includes four 3/16 in. mounting holes.
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”.
