Bearing life (ISO 281 basic rating life)

C / P	Equivalent load P (N)	L₁₀ (10⁶ rev)	L_10h at 2,000 rpm
4	9,625	102	847
6	6,417	392	3,271

10	3,850	2,154	17,954
15	2,567	8,323	69,362

Basic rating life per ISO 281: L₁₀ = (C/P)^10/3 with C = 38,500 N. Hours = L₁₀ x 10⁶ / (60n). Life-modification factors for lubrication, contamination and temperature (a_ISO) are not included.
