What these specs mean in practice

Dynamic Radial Load Rating (C1, 1M revs): 99,800 N (22,400 lbf). Dynamic Radial Load Rating (C90, 90M revs): 25,900 N (5,810 lbf). Dynamic Axial Rating (Ca90): 34,600 N (7,770 lbf). Static Radial Load Rating (C0): 88,600 N (19,900 lbf). K Factor: 0.75. A K factor of 0.75 marks a steep raceway angle, so this cone carries a high thrust share for its size — the axial rating of 34,600 N is a third of the radial figure. G1 Factor: 22.9. G2 Factor: 8.7. Geometry Factor (Cg): 0.0899. Item weight: 1.671 kg (3.68 lb).
