K Series Bevel Gear Reducer
The K series is a compact right-angle helical-bevel gear reducer designed to reduce speed and transmit torque in industrial machinery.
Product Overview
The K series is a right-angle helical-bevel gear reducer designed to reduce speed and transmit torque in industrial drive systems. Its compact layout allows the input and output shafts to be arranged at 90 degrees.
Typical applications include conveyors, material-handling equipment and processing machinery. Depending on the model, solid or hollow output shafts and foot, flange or shaft-mounted arrangements may be available.
Select the reducer according to the required output speed, torque, service factor and operating cycle. Before installation, verify shaft dimensions, mounting interfaces, permissible shaft loads and lubrication requirements using the model-specific documentation.

Frequently Asked Questions
Provide the required output speed, torque, motor power, operating hours, starting frequency and mounting position. Include shock loads and any radial or axial forces acting on the output shaft.
K series reducers use a right-angle helical-bevel arrangement, while F series reducers typically use a parallel-shaft helical arrangement. Select the layout that suits your equipment and installation space.
Divide the input speed by the required output speed to estimate the ratio. Then 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 power, electrical supply, mounting interface and any brake requirements when ordering.
Availability depends on the model. Confirm the shaft or bore diameter, connection method and installation requirements using the selected unit’s drawing.
