Boston Gear F724-40-B5-G Speed Reducer 40:1 ratio 56C frame
A worm-gear speed reducer delivering 40:1 reduction with a 56C C-face input for 44 RPM output and 1206 in-lb torque
- 40:1 worm gearing delivers precise 44 RPM output speed
- 1 hp input rating handles up to 1206 in-lb output torque
- 56C C-face mounting fits standard NEMA motor frames directly
- Cast iron housing with tapered roller bearings supports 150 lb overhung load
- Any-angle mounting orientation allows flexible installation in tight spaces
40:1 Speed Reducer for 56C Motors
This worm-gear reducer provides a 40:1 ratio for 56C-frame motors with a C-face input connection. It suits applications that need a fixed reduction to 44 RPM maximum output speed and up to 1 hp input power. The cast-iron housing and tapered roller bearings support continuous operation at any mounting angle.
Hardened Steel Worm Gear and 1206 in-lb Torque
The hardened and ground steel worm delivers a maximum output torque of 1206 in-lb while the tapered roller bearings handle a 150 lb overhung load capacity. The 2.38 in worm center distance and 2.5 in base-to-center height set the mounting footprint for direct coupling to driven equipment.
CW/CCW Rotation and Single-Speed Operation
Rotation is selectable clockwise or counter-clockwise but the unit provides only the fixed 40:1 ratio with no variable-speed capability. Buyers who need a different reduction ratio or higher output speeds must choose another model. The housing contains chemicals listed under California Proposition 65 for cancer and reproductive harm.

Questions about this item
What oil changes or seal replacements does the F724-40-B5-G speed reducer need over time?
The unit uses standard gear lubricant; plan periodic oil changes and inspect the input and output seals for wear during routine maintenance.
At continuous 44 RPM output, which limit appears first — the 1 hp input rating or the 1206 in-lb torque ceiling?
The 1 hp maximum input horsepower is the limiting factor at 44 RPM; exceeding it would surpass the reducer’s rated capacity before the 1206 in-lb torque limit is reached.
How much heat and noise should I expect when the reducer runs all day at 1 hp input?
Cast-iron housing and tapered roller bearings dissipate heat effectively; expect moderate warmth and low mechanical noise at the rated 1 hp continuous load.
