WebJul 28, 2024 · 6.5: Bearing Friction. A bearing is the machine element used to support a rotating shaft. Bearing friction is the friction that exists between the rotating shaft and bearing that is supporting that shaft. Though many types of bearings exist (plain, ball, roller, hydrodynamic), in this course we will only be looking at plain bearings, also ... WebJan 23, 2024 · Rolling friction is the force that opposes the motion of a rolling body. Whenever a ball is rolling on the ground, it eventually comes to halt. This is because the ball is experiencing resistance in the direction of its motion, i.e. some force is opposing its motion and drags down the speed of the ball. This opposing force is known as rolling ...
