Speed Reducer for 56C Motors
The Boston Gear F713-20-B5-G is a worm-gear speed reducer built for 56C frame motors with a C-face input. It provides a fixed 20:1 reduction ratio and delivers a maximum output torque of 308 in-lb at speeds up to 88 RPM.
Practical Limits of Worm-Gear Reduction
The unit accepts a maximum input of 0.5 hp and handles overhung loads up to 150 lb on the output shaft. Hardened steel gears and tapered roller bearings operate inside a cast-iron housing rated for any mounting orientation.
20:1 Ratio Defines Output Speed and Torque
A 20:1 gear ratio sets the output at roughly one-twentieth of motor speed while multiplying torque twenty-fold. Select this reducer only when the application requires exactly that speed reduction and the 308 in-lb torque ceiling meets the load demand.
