Static load rating. The basic static load rating C 0 is defined in ISO 76 as the load that results in a certain value of contact stress at the centre of contact of the most heavily loaded rolling element/raceway. The contact stress values are: 4 600 MPa for self-aligning ball bearings. 4 200 MPa for all other ball bearings.
