5. Friction torque of roller or needle bearings and thrust bearings
Friction in a bearing generates heat, which affects the operating temperature. Total rolling resistance consists of friction:
rolling in the rolling element/track contacts;
sliding in the cage/rolling element contacts and cage on guide ring;
viscosity of the lubricant;
and seals in protected bearings.
In the 1930s and 1940s, A. Palmgren established semi-empirical expressions for the friction torque of bearings. ....
