Boston Gear 52032 Single Shaft Speed Reducer 25:1 56C Nema

Product Description

The BOSTON GEAR 52032 is a single-shaft worm gear speed reducer designed for industrial drive applications where precise speed reduction and reliable torque output are required. With a 25:1 reduction ratio and a 56C NEMA frame mount, this unit delivers an output speed of 70.0 RPM at a 1750 RPM input. Torque output reaches 780 in-lb with a 1 horsepower motor, 1170 in-lb with a 1.5 horsepower motor, and 1514 in-lb with a 2 horsepower motor at 1750 RPM input. Weighing 45 pounds, this is a robust unit suited for demanding speed-reduction duty cycles.

The 52032 is used in industrial and commercial drive systems requiring controlled output speeds from standard AC motor inputs. The 56C NEMA face mount configuration allows direct coupling to NEMA 56C frame motors, making it a common choice for conveyor drives, material handling equipment, mixers, and similar power-transmission applications. The projecting base type supports flexible mounting arrangements in tight drive assemblies. Installation is performed by qualified mechanical or industrial maintenance technicians.

Compatibility

Designed for use with NEMA 56C frame motors. Consult the BOSTON GEAR product documentation to confirm compatibility with specific motor horsepower ratings and input shaft configurations before installation.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with industrial power-transmission equipment. Disconnect and lock out all power sources before mounting or servicing the reducer. Verify that the motor shaft and reducer input bore alignment meet manufacturer tolerances before final assembly. Confirm that mounting fasteners are secured and that the output shaft load does not exceed the rated torque values for the connected motor horsepower.
