Tribology basics for linear bearings

17/10/2018· Tribology basics for linear bearings. October 17, 2018 By Danielle Collins 1 Comment. Tribology is the study and appliion of the principles of friction, lubriion, and wear between two surfaces in relative motion. In linear bearing systems, those two surfaces are the bearing element and the guide raceway.

Friction | SKF

The friction in a spherical plain bearing or rod end depends primarily on the sliding contact surface coination, the load and the sliding velocity. Because there are so many influencing factors that are not mutually independent, it is not possible to quote exact values for the coefficient of friction. Under laboratory conditions, however, it

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.
