Bearing life (ISO 281 basic rating life)

C / P	Equivalent load P (N)	L₁₀ (10⁶ rev)	L_10h at 3,000 rpm
4	13,250	102	564
6	8,833	392	2,181
8	6,625	1,024	5,689
10	5,300	2,154	11,969
15	3,533	8,323	46,241

Basic rating life per ISO 281: L₁₀ = (C/P)^10/3 with C = 53,000 N. Hours = L₁₀ x 10⁶ / (60n). Life-modification factors for lubrication, contamination and temperature (a_ISO) are not included.
