Universal compatibility with NEMA C-face motors, a hollow bore output, and a broad range of power and output torques support many industrial process applications. The WorldWide Electric FHN Parallel Shaft Helical Speed Reducers reduce output speed (RPM) and increase torque. The helical gear design provides high efficiency for your applications, such as driving belt, screw and chain conveyors, presses, extruders, and gantry cranes.
