Bearing life (ISO 281 basic rating life)

C / P	Equivalent load P (N)	L₁₀ (10⁶ rev)	L_10h at 1,700 rpm
4	56,000	102	996
6	37,333	392	3,848

10	22,400	2,154	21,122
15	14,933	8,323	81,603

Basic rating life per ISO 281: L₁₀ = (C/P)^10/3 with C = 224,000 N. Hours = L₁₀ x 10⁶ / (60n). Life-modification factors for lubrication, contamination and temperature (a_ISO) are not included.
