Six factors related to bearing life:
(1) Load P [N/mm2] Load
The greater the load, the shorter the bearing life; the greater the load fluctuation, the greater the impact on the bearing life, the shorter the bearing life; in any case, the maximum load must not exceed the theoretical maximum allowable load value. The load size is equal to the actual working load divided by the projected area of the bearing, the formula is P=F/(D*B).
(2) Velocity V [m/s] and PV value
The operating life of the bearing depends on the magnitude of the PV value, i.e. the product of the actual load P [N/mm2] and the sliding speed V [m/s], the smaller the PV value, the longer the bearing life.
(3) Temperature T [oC]
Bearing life also depends on the temperature when the bearing is in use, so the heat dissipation characteristics of the relevant parts should be taken into account as much as possible when designing the selection.
(4) Surface roughness of the parts to be ground
The surface roughness of the contact surface of the bearing should be between Ra0.2~Ra0.8. The bearing should not be damaged by sharp media during assembly and use.
(5) on the grinding parts surface material, on the grinding parts surface roughness is a factor that affects the life of the bush, in general a surface requirements to ≤ 0.4μm ka.
(6) Other factors such as the design of the bearing housing, lubrication conditions, etc.
