Bearing life (ISO 281 basic rating life)

C / P	Equivalent load P (N)	L₁₀ (10⁶ rev)	L_10h at 3,000 rpm
4	5,725	102	564
6	3,817	392	2,181

10	2,290	2,154	11,969
15	1,527	8,323	46,241

Basic rating life per ISO 281: L₁₀ = (C/P)^10/3 with C = 22,900 N. Hours = L₁₀ x 10⁶ / (60n). Life-modification factors for lubrication, contamination and temperature (a_ISO) are not included.
