1: straight bushing
2: flanged sleeve bushing
3: the plate
1: load P: the greater the load, the shorter the service life of the bearing;Under no circumstances shall the maximum load exceed the theoretical maximum allowable load.
2: speed V: the higher the speed, the shorter the service life of the bearing;Under no circumstances shall the maximum sliding speed exceed the theoretical maximum allowable value.
3: PV value: the working life of the bearing depends on the PV value, that is, the product of the actual load P and the sliding speed V. The smaller PV value is, the longer the bearing life is.
4: temperature: the life of the bearing also depends on the temperature when the bearing is in use, the higher the temperature, the shorter the life of the bearing, so in the design and selection should try to consider the heat dissipation characteristics of the relevant parts.
5: surface roughness of the grinding parts: alloy steel or hard chromium plated shaft is used for the grinding parts. When the surface roughness Ra=0.4-0.63, the service life of the bearing can be significantly improved.
6: other factors such as bearing design, lubrication conditions, etc
