The A 2Z1A-D21 is a 2:1 miniature right angle helical gear drive with dual output shafts, designed for speed reduction. It has an aluminum anodized housing, hardened steel gears, steel shafts, and stainless steel bearings. The unit measures 2.50 inches in length, 1.875 inches in width, and 1.250 inches in height, with .250 inch diameter input and output shafts. It is rated for a maximum continuous input speed of 1800 rpm and a power capacity of 1/8 hp. The output shafts feature #10-24 threads, 9 places, and are .350 inch deep. The unit is not intended for use as a speed increaser.
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”.
