Frictional coefficient (reference) | Basic Bearing Knowledge | Koyo Bearings …
The friction coefficient is greatly dependent on bearing type, bearing load, rotation speed and lubriion, etc. Reference values for the friction coefficient during stable operation under normal operating conditions are listed in Table 8-1. For plain bearings, the value is normally 0.01 to 0.02 ; but, for certain cases, it is 0.1 to 0.2.
Friction | SKF | SKF
Friction. Load, sliding velocity, operating temperature are primary factors in determining the friction in plain bearings. Friction is also influenced by the roughness of the surface on which the bearing runs, the degree of contamination and the lubriion conditions. The range of the friction coefficient µ for each bushing, thrust washer and

S Bearings, EZO bearings, Bearing Relubriion Services - What types of bearing are very low friction?
For low friction appliions, a very light instrument oil or small amount of low torque grease should be considered. Ceramic bearings are a good option for low torque appliions. The material has a low coefficient of friction so these bearings can be used without lubriion. As a result, ceramic ball bearings are well-known for providing
