Coefficient of Friction | AVSLD International
Coefficient of Friction. The coefficient of friction, often syolized by the Greek letter µ, is a dimensionless scalar value which describes the ratio of the force of friction between two bodies and the force pressing them together.The coefficient of friction depends on the materials used; for example, ice on steel has a low coefficient of friction, while rubber on pavement has a …

Sliding Bearing - an overview | ScienceDirect Topics
Typical coefficients of friction for a boundary lubried bearing are between approximately 0.05 and 0.1. By contrast the coefficient of friction for a rolling element bearing is typically of the order of 0.005. In general, boundary lubriion is used for slow speed appliions where the surface speed is less than approximately 1.5 m/s.
