Friction coefficient range of various rolling bearings
Calculation method of rolling bearing type and its dynamic friction coefficient μ:

μ= M/（P*(d/2)）

M: Dynamic friction moment (n · mm), {KGF · mm}

P: Bearing load (equivalent dynamic load) (n), {KGF}

d: Shaft diameter, inner diameter of inner ring (mm)
