Contact fatigue failure refers to the failure of the bearing working surface due to the effect of alternating stress. Contact fatigue falls on the working surface of sliding bearings, which is often accompanied by fatigue cracks, mainly from the maximum...

The viscosity of lubricating oil decreases with the increase of temperature, so the viscosity of the same kind of lubricating oil is different because of different temperature. This property is called "viscosity-temperature characteristic...

When the grease performance of the bearing is poor under the radial load, the "click, click" noise will be heard at the initial stage of operation, which is mainly due to the noise...

According to the rotation of the load on the bearing relative to the ring, the ring bearing load has three kinds: local load, cyclic load, swing load. Usually cyclic load (rotating load) , swing load with tight fit...

The selection of specification size and accuracy according to the use position, use conditions and environmental conditions, and the matching of suitable tapered roller bearings is the premise to ensure the bearing...
