Boston Gear 30:1 Speed Reducer

The Boston Gear F713-30-B5-G is a worm-gear speed reducer with a 30:1 ratio and a 56C C-face input. It delivers a maximum output speed of 58 RPM and a maximum output torque of 208 in-lb. The cast-iron housing contains hardened and ground steel gears on tapered roller bearings. It accepts a maximum input of 0.25 hp and mounts at any angle.

Suited for low-speed, high-torque drives

This unit fits applications needing a 30:1 reduction from a 56C-frame motor where 58 RPM output meets the requirement. The 200 lb overhung load capacity supports moderate radial forces. Builders needing a different ratio, higher input horsepower, or a hollow output shaft should look at other models.

Questions about this item

What motor frame must I already have to mount the 56C C-face speed reducer?

The unit is built for a NEMA 56C frame motor with a C-face input connection.

Will the 30:1 worm gear ratio and 58 RPM maximum output speed suit an older 0.25 hp motor I plan to keep?

Yes, the reducer accepts up to 0.25 hp input and delivers 58 RPM at 30:1 ratio.

How can I confirm the reducer is producing the rated 208 in-lb output torque after installation?

Measure output torque under load; it should reach 208 in-lb at the 30:1 ratio with the motor at full rated power.
