For iglide 181, the coefficient of friction µ is dependent on the surface speed of the shaft along with the shaft surface finish although generally speaking the effect is negligible as the table below represents. The coefficient of friction increases quickly with any load under 725 psi. s the load increases the coefficient of friction reduces drastically.
