The Boston Gear F7715-20-B5-G is a worm-gear speed reducer built for a 56C motor frame. It provides a fixed 20:1 reduction ratio and is rated for a maximum input of 0.5 hp, delivering up to 295 in-lb of output torque.
Suitable for fixed-speed machinery needing
This unit suits equipment that requires a 20:1 ratio and can accept a C-face motor. It is not for applications needing a different ratio, a higher input horsepower, or an output speed above 88 RPM.
20:1 gear ratio defines the output speed
The single specification that decides fit is the 20:1 gear ratio, which sets the maximum output speed at 88 RPM and determines the torque multiplication for the driven load.
