Bearing life (ISO 281 basic rating life)

C / P	Equivalent load P (N)	L₁₀ (10⁶ rev)	L_10h at 3,000 rpm
4	3,675	64	356
6	2,450	216	1,200
8	1,838	512	2,844
10	1,470	1,000	5,556
15	980	3,375	18,750

Basic rating life per ISO 281: L₁₀ = (C/P)³ with C = 14,700 N. Hours = L₁₀ x 10⁶ / (60n). Life-modification factors for lubrication, contamination and temperature (a_ISO) are not included.
