6. Bearing Load Calculation - Welcome to NTN Bearing

6.2 Bearing load distribution For shafting, the static tension is considered to be supported by the bearings, and any loads acting on the shafts are distributed to the bearings. For example, in the gear shaft assembly depicted in Fig. 6.7, the applied bearing loads can be found by using formulas (6.10) and (6.11). where, FrA : Radial load on

Ball Bearings: Guide to selection, applications

Calculation of bearing life The bearing life calculations means, the life of an individual bearing in terms of revolutions that can be utilized under continuous operating conditions designed to specific system operating conditions. L 10 = (106/60n) x (C/P) 3. Where, L 10 = Life of an individual bearing in hours under continuous run.
