An expanded series of 41 miniature inch and metric right angle speed reducers introduced by Stock Drive Products are designed to operate in any output direction: reverse, same or dual. They are ideal for connecting accessory instruments, for reversing rotation of flexible shafts and for controlling two units through one power source. These versatile, lightweight, 4 oz. (113g), units, identified as the A 2Z23- (inch series) and A 2Z23M (metric series), come with twin hex nuts that simplify mounting the units onto panels.

These low-cost reducers employ crossed-helical gears that provide a wide range of 8 output ratios. The reducers are finding increased use in intermittent-duty applications where input motion by means of a control knob or gear is transmitted at right angles to the output shaft. These reducers are also excellent for continuous, light-duty use where they can operate at speeds of about 1,800 rpm. These miniature, 2-1/2" (64 mm) wide X 3-1/32" (77 mm) deep X 1-5/32" (29.4 mm) high, units are easily mounted through a 9/16" panel hole and secured with twin hex nuts. Either right-handed or left-handed units may be ordered. Gear ratios range from 1:1 (where they may be operated from either shaft acting as the output shaft) to 25:1, with horsepower ratings ranging from 1/20 to 1/8 HP. The units feature a black-anodized die-cast aluminum housing with hardened steel helical gears, steel shafts, threaded brass bushings and comes complete with a grease fitting. Input and output shaft diameters are .250" (6 mm). Manual torque capacities for units up to 5:1 gear ratios are 28 lb.in. (3.2 Nm), and above 5:1 gear ratios are 20 lb.in. (2.3 Nm).
