In order to facilitate comparison with the sliding bearing, rolling bearing friction torque can be calculated by the bearing inner diameter by the following formula: M = uPd / 2 Here, M: friction torque, mN.m U: coefficient of friction, P: bearing load, N D: bearing nominal diameter, mm Friction coefficient u by the bearing type, bearing load, speed, lubrication, etc. greater impact, under normal conditions, stable rotation of the friction coefficient reference value shown in Table 1. For plain bearings, u = 0.01-0.02, sometimes up to 0.1-0.2. Various types of bearing friction coefficient u Bearing type friction coefficient u Deep groove ball bearings 0.0010-0.0015 Angular contact ball bearings Self-aligning ball bearings 0.0008-0.0012 Cylindrical Roller Bearings: 0.0008-0.0012 Full complement needle roller bearings Needle roller bearings with cage 0.0020-0.0030 Tapered roller bearings Spherical roller bearings Thrust ball bearings 0.0010-0.0015 Thrust spherical roller bearings 0.0020-0.0025 |
