- coefficient of friction rubber wet conveyor idler
A simple, as well as an effective model for friction, is that the force of friction, f, is equal to the product of the normal force, N, and a number called the coefficient of friction, μ. It means. F= N × μ. This normal …

The coefficient of friction is the ratio of a force to a force, and hence has no units. Typical values for the coefficient of friction when sliding is occurring, i.e. the dynamic coefficient of friction are: for polished oiled metal surfaces, less than 0.1. for glass on glass, 0.4. for rubber on tarmac, close to 1.0.
