The Output Shaft Carries more than Driving Torque

A planetary gearbox may meet your torque and speed requirements, but what other loads will its output shaft carry? Radial and axial forces also need consideration when assessing suitability and bearing life.

Before selecting a gearbox, check:

• Required output torque and speed.
• Operating du...
