Cast iron worm gear speed reducer with round output shaft, C-face 56C input, 60:1 ratio, .5 hp, 670 in-lb torque

Boston Gear

Boston Gear F724-60-B5-G Speed Reducer 56C 60:1 .5 hp 670 in-lb

SKU CH-7P8H-H0923

Worm-gear speed reducer with 56C C-face input, 60:1 ratio, .5 hp rating and 670 in-lb output torque

  • Worm gear design provides smooth, quiet power transmission
  • 60:1 ratio delivers high torque multiplication for heavy loads
  • Cast iron housing resists wear in demanding environments
  • Tapered roller bearings support 150 lb overhung load capacity
  • .5 hp input rating matches 56C motor frame requirements

Industrial Speed Reducer for 56C Motors

This Boston Gear F724-60-B5-G unit provides a 60:1 reduction ratio for 56C-frame motors rated up to .5 hp. It delivers a maximum output torque of 670 in-lb at speeds up to 29 RPM. The cast-iron housing accepts mounting at any angle for flexible installation.

Thermal Performance and Power Draw

The hardened and ground steel worm gear operates within a cast-iron housing that dissipates heat during continuous duty. Tapered roller bearings support the output shaft and manage the rated overhung load of 150 lb. The unit draws a maximum input of .5 hp to produce the rated output torque.

Sustained Load Behaviour

Under continuous operation the 60:1 gearing maintains consistent output speed and torque without the drop-off seen in short-cycle testing. The worm design provides inherent self-locking resistance to back-driving when power is removed. Lubrication must be maintained to preserve the 670 in-lb torque rating over extended run periods.

Questions about this item

How do I mount the Boston Gear F724-60-B5-G speed reducer to a 56C frame motor?

Bolt the unit's C-face input directly to the 56C motor flange, ensuring the pilot seats fully before tightening the four mounting bolts to the specified torque.

What lubrication schedule does the worm gear reducer require?

The cast-iron housing is factory-filled with transmission fluid; drain and refill after the initial break-in period and then at regular intervals based on operating temperature and duty cycle.

At what output speed does the 60:1 ratio reducer reach its thermal limit under continuous load?

With a maximum output speed of 29 RPM, sustained operation at full 670 in-lb torque will hit the housing's heat-dissipation capacity before mechanical ratings are exceeded.
