Bearing life (ISO 281 basic rating life)

C / P	Equivalent load P (N)	L₁₀ (10⁶ rev)	L_10h at 1,200 rpm
4	92,500	102	1,411
6	61,667	392	5,451

10	37,000	2,154	29,923
15	24,667	8,323	115,604

Basic rating life per ISO 281: L₁₀ = (C/P)^10/3 with C = 370,000 N. Hours = L₁₀ x 10⁶ / (60n). Life-modification factors for lubrication, contamination and temperature (a_ISO) are not included.
