Speed Reducers for Face-Mount AC Motors
Mount these speed reducers to a NEMA 56C motor. They transmit motion parallel to the motor shaft while reducing speed and increasing torque. Spur gears minimize torque loss between your motor and drive shaft, making these speed reducers more efficient than our other speed reducers. All require lubrication (not included).
Radial loads are loads that are perpendicular to the shaft. They’re commonly caused by components attached to shaft, such as pulleys and sprockets.

Gear Boxes for Linear Motion
Convert rotary motion to linear motion. As the input shaft spins, a gear rack moves back and forth to adjust components in position and lifting applications. Gear boxes require lubrication (not included). Connect the input shaft to a motor using a shaft coupling (not included). Mesh the gear rack with a spur gear or attach to a load using the mounting holes on either end of the gear rack. When meshing the gear rack with a gear, be sure the rack and gear have the same pressure angle and module.
Radial loads are loads that are perpendicular to the shaft. They’re commonly caused by components attached to shaft, such as hand cranks and motors.

Gear Boxes for Mirrored Linear Motion
A set of gear racks converts rotary motion into linear motion in opposite directions at the same time. As the input shaft spins, the gear racks move back and forth to adjust components in position and lifting applications. Gear boxes require lubrication (not included). Connect the input shaft to a motor using a shaft coupling (not included). Mesh gear racks with a spur gear or attach to a load using the mounting holes on either end of the gear racks.
