• Gearmotor sizing guide | Machine Design

An overhung load is a force applied at right angles to a reducer shaft. The problem with such a load is that it causes a bending force in the shaft that must be resisted by the reducer shaft as well as the bearings. Whenever a pulley, sprocket, gear, or cable assembly is directly mounted on a reducer shaft you can expect a bending force.
