Bearing life (ISO 281 basic rating life)

C / P	Equivalent load P (N)	L₁₀ (10⁶ rev)	L_10h at 3,000 rpm
4	4,000	64	356
6	2,667	216	1,200

10	1,600	1,000	5,556
15	1,067	3,375	18,750

Basic rating life per ISO 281: L₁₀ = (C/P)³ with C = 16,000 N. Hours = L₁₀ x 10⁶ / (60n). Life-modification factors for lubrication, contamination and temperature (a_ISO) are not included.
