SKU CH-GGBA-XM5R5

Worm-gear speed reducer with 56C C-face input, 5:1 ratio, 350 RPM max output, 82 in-lb torque and 150 lb overhung load capacity

  • 5:1 ratio delivers precise speed reduction for 56C motors
  • 5 hp input handles moderate power transmission tasks
  • 82 in-lb output torque drives light industrial loads
  • 350 RPM maximum output suits slower-speed applications
  • Cast iron housing with tapered roller bearings ensures durability

Speed Reducer for 56C Motors

The Boston Gear F710-5-B5-G is a worm-gear speed reducer built for a 56C motor frame. It delivers a fixed 5:1 reduction ratio with a maximum output speed of 350 RPM. The unit accepts a maximum input of .5 horsepower and provides up to 82 in-lb of output torque.

Replaces Larger or Direct-Drive Setups

This reducer suits applications that need lower speed and higher torque from a .5 hp motor without moving to a larger frame size. The jump is worth it when space is limited and the 1-inch worm center distance fits the mounting envelope. It is not suited for loads exceeding 150 lb overhung capacity or for ratios other than 5:1.

Worm-Gear Constraints and Mounting

The cast-iron housing mounts at any angle using tapered roller bearings and hardened, ground steel gearing. Rotation is reversible in both CW and CCW directions. California Proposition 65 warnings apply for cancer and reproductive harm. Buyers needing higher input power or different output shaft configurations must select another model.
