The friction coefficient of bearing

by:Waxing     2020-06-01
Compared with sliding bearing, for ease of rolling bearing friction torque can be calculated on bearing inner diameter by type: M = uPd / 2 here, M: friction torque, mN. Mu: the coefficient of friction, table 1 p: bearing load, Nd: bearing nominal diameter, mm u friction coefficient by the bearing type, bearing load, speed and lubrication method is larger, the influence of general stability when rotating friction coefficient under the condition of reference as shown in table 1. For the sliding bearing, the general u = 0. 01 - 0. 02, sometimes up to 0. 1 - 0. 2. All kinds of bearing friction coefficient u bearing type u deep groove ball bearing friction coefficient 0. 0010 - 0. Angular contact ball bearing 0015 0. 0012 - 0. Self-aligning ball bearing 0020 0. 0008 - 0. Cylindrical roller bearing 0012 0. 0008 - 0. 0012 full needle bearing 0. 0025 - 0. 0035 maintains a needle roller bearing 0. 0020 - 0. Taper roller bearings 0030 0. 0017 - 0. Self-aligning roller bearing 0 0025. 0020 - 0. Thrust ball bearing 0025 0. 0010 - 0. Thrust spherical roller bearing 0 0015. 0020 - 0. 0025
