Boston Gear 56C Worm Reducer

The Boston Gear F710-10-B5-G is a worm-gear speed reducer built for a NEMA 56C motor frame. It provides a fixed 10:1 reduction with a 1-inch worm center distance and a 1.31-inch base-to-center height. The unit delivers a maximum output speed of 175 RPM and a peak output torque of 107 in-lb.

Suits constant-speed conveyor drives

This reducer suits applications needing a single, right-angle output at a steady 175 RPM maximum. It is not for variable-speed systems, high-cycle indexing, or installations requiring a hollow output bore. Buyers needing a different ratio or a flange-mounted output should look at other models.

Cast-iron housing handles sustained load

A cast-iron housing with tapered roller bearings dissipates heat during continuous duty. The hardened and ground steel worm gear maintains the 107 in-lb torque rating under prolonged operation without the thermal fade common in lighter housings. The 150 lb overhung load capacity supports shaft-mounted pulleys or sprockets during extended runs.

Highlights

  • Delivers 107 in-lb output torque with a 10:1 gear ratio
  • Handles 150 lb overhung load for reliable shaft support
  • Operates at up to 175 RPM maximum output speed
  • Cast iron housing with hardened steel gears ensures durability
  • Mounts at any angle with 56C motor frame compatibility

Questions about this item

Will my 56C-frame motor bolt straight to the C-face input?

Yes, the reducer is built for a 56C motor frame and uses a C-face input connection.

If I keep my existing 10:1 reducer, will the output shaft height match this unit?

This unit has a 1.31 in base-to-center height and a 1 in worm centre distance; check your old unit against those figures.

How can I confirm the reducer is delivering the rated 107 in-lb after installation?

Run the motor at full load and measure output torque; it should reach 107 in-lb without exceeding the 150 lb overhung-load limit.
