Generally speaking; according to the ISO 281:1990 specification; the fundamental extra life of imported bearings is: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
L10=
If the speed is fixed; the life of the FAG bearing is usually indicated by the working hours; the formula is:
The interpretation in the formula is:
L10: Fundamental extra life (90% reliability); Million to L10h: Fundamental extra life (90% reliability); Hours of operation C: Fundamental extra dynamic load; kN
P: equivalent dynamic load; kN
n: speed; r/min
P: index in the life formula; FAG bearing ball bearing is 3; FAG bearing roller bearing is 10/3
