Bearing life (ISO 281 basic rating life)

C / P	Equivalent load P (N)	L₁₀ (10⁶ rev)	L_10h at 1,400 rpm
4	62,500	102	1,209
6	41,667	392	4,673

10	25,000	2,154	25,648
15	16,667	8,323	99,089

Basic rating life per ISO 281: L₁₀ = (C/P)^10/3 with C = 250,000 N. Hours = L₁₀ x 10⁶ / (60n). Life-modification factors for lubrication, contamination and temperature (a_ISO) are not included.
