F Series Helical Gear Reducer


Typical applications include conveyors, material-handling equipment and processing machinery. Depending on the selected model, the reducer may be supplied with a solid or hollow output shaft and different mounting arrangements.
Select the unit according to the required output speed, torque, service factor and operating cycle. Verify shaft dimensions, mounting interfaces, permissible shaft loads and lubrication requirements before installation.

Provide the required output speed, torque, motor power, operating hours, starting frequency and mounting position. Include any shock loads and radial or axial forces acting on the output shaft.
The F series described here uses a parallel-shaft arrangement. Check the dimensional drawing to confirm the shaft positions and installation layout.
Divide the input speed by the required output speed to estimate the ratio. Select an available ratio and verify output torque, service factor and gearbox capacity.
Motorized units and motor-adapter configurations may be available. Confirm the motor rating, electrical supply, mounting interface and any brake requirements when ordering.
Availability depends on the model. Confirm the shaft or bore diameter, connection method and mounting requirements using the selected unit’s drawing.
