Six factors related to bearing life:
(1) [N/mm2] Load P
Larger loads and bearing service life is short; load fluctuation is bigger, larger influence on bearing life, bearing shorter life expectancy; whether, in any case, the maximum load can not be more than the theoretical maximum permissible value of the load. The load is equal to the actual working load divided by the area of the bearing, the formula is P=F/ (D*B).
(2) speed [m/s] V and PV
The working life of the bearing depends on the PV value, that is, the actual load [N/mm2] P and the sliding speed [m/s] V product, the smaller the PV value, the longer the bearing life.
(3) [oC] T
Bearing life also depends on the use of the bearing temperature, so in the design and selection of the relevant parts of the heat dissipation characteristics.
(4) surface roughness of grinding parts
The contact surface roughness of the parts of the bearing and the bearing of the bearing should be between Ra0.2~Ra0.8, and the bearing can not be sharp in the process of assembly and use.
(5) parts of the surface material of grinding, grinding parts surface rough degree is a factor influencing the service life of the shaft sleeve, generally a surface requirements reach less than or equal to 0.4 m Ka.
(6) other factors such as the design of the bearing seat, the lubrication condition, etc..
