Full definition
Constant radial load that a bearing can carry to reach a nominal L10 life of exactly 1,000,000 revolutions. Expressed in kN in manufacturer catalogs. Example: SKF 6205 has C = 14 kN; 6305 has C = 22.5 kN. Used in ISO 281 life calculations. Depends on bearing type, geometry, number and diameter of rolling elements and steel quality. ISO 281 standard. Brands: SKF, NSK, FAG, NTN.
