Dynamic bearing capacity
WebDynamic load ratings are determined by bearing geometry, number and size of balls, bearing pitch diameter, and ring and ball material. This load rating is used in conjunction with the actual applied radial load to calculate bearing fatigue life. The static load rating relates to limiting loads applied to non-rotating bearings. WebAxial load carrying capacity: Pure axial load → F a ≤ 0,25 C 0 Excessive axial load can lead to a considerable reduction in bearing service life. Equivalent dynamic bearing load For additional information → Equivalent dynamic bearing load, P: F a /F r ≤ e → P = F r F a /F r > e → P = X F r + Y F a Use SKF Bearing Select. Equivalent ...
