Static Load Carrying Capacity

Static load carrying capacity (C0) of a rolling contact bearing is defined as the maximum static load for which the combined permanent deformation of the rolling element and races at any point does not exceed 0.0001 times that of the rolling element diameter.

Based on Hertz contact stresses, Stribeck’s equation defines the static load carrying capacity of a bearing with certain assumptions. For number of balls z and diameter d, Striebeck’s equation is written as

C₀ = k d² z⁵

where k is a constant of proportionality
