Boston Gear 718 Worm Reducer
This Boston Gear 718 speed reducer uses a 10:1 worm gear ratio to deliver up to 460 in-lb of output torque from a 1.5 hp input. It suits industrial machinery that requires right-angle power transmission in a compact footprint. The unit accepts a standard 56C motor frame via its C-face input connection.
Cast Iron Housing Tapered Roller Bearings
The housing is cast iron with hardened and ground steel gears running on tapered roller bearings. A 1.75 in worm centre distance and 2.06 in base-to-centre dimension fix the mounting geometry. The round output shaft rotates clockwise or counter-clockwise and the reducer can be installed at any angle.
175 RPM Output 150 lb Overhung Load
Maximum output speed is 175 RPM, which limits the reducer to slower driven equipment. Overhung load capacity is rated at 150 lb, so radial forces on the output shaft must stay within that value. The product carries California Proposition 65 warnings for cancer and reproductive harm.

Questions about this item
What does the 10:1 gear ratio mean for output speed and torque?
The 10:1 ratio reduces input speed by a factor of ten, giving a maximum output speed of 175 RPM while multiplying torque up to 460 in-lb.
Will the 56C C-face mount match my motor and frame?
The reducer accepts a NEMA 56C C-face motor; its worm center distance is 1.75 in and base-to-center height is 2.06 in for alignment.
How do I install the reducer and what step is often missed?
Mount at any angle using the cast-iron housing bolts, fill with the correct transmission fluid before startup, and verify the 150 lb overhung load limit on the output shaft.
