Coefficient of Friction
The dynamic coefficient of friction for MOSTUF composite bearing is between 0.03 ~ 0.12, depending upon load, type of movement, sliding speed, operating temperature, micro finish of mating surface. Fig.5 shows the change of dynamic coefficient of friction under oscillating load. At the beginning of test, coefficient of friction is being kept up on steady-state conditions
