I believe you are not unfamiliar with roller bearings. Roller bearings mainly rely on rolling contact between parts to support rotating parts. So different roller bearings bear different axial and radial forces, so the use environment has a great impact on roller bearings. Let's talk about the impact of environment on roller bearings from Zhejiang roller bearing factory.
It is the premise to ensure the service life and reliability of angular contact ball bearing to select the gauge size, accuracy and suitable bearing according to the use position, use conditions and environmental conditions. Angular contact ball bearing is suitable for bearing the combined radial and axial load with radial load as the main load. It is usually used with two sets of bearings in pairs. It is mainly used in the front and rear wheel hub, driving bevel gear, differential, reducer and other transmission parts of automobile.
Under the condition of correct installation and good lubrication, it is allowed to be 0.3-0.5 times of the bearing limit speed. Under normal conditions, 0.2 times of the limit speed is appropriate. Tapered roller bearings generally do not allow the shaft to tilt relative to the shell hole, if there is tilt, not more than 2 '.
Under the condition of normal load, high temperature resistance and sufficient lubrication, the general angular contact ball bearing is allowed to work at the ambient temperature of - 30 ℃ - 150 ℃. These are the impact of the use environment on the roller bearing, must be used according to the requirements.
To sum up, the environment has a great impact on the use of roller bearings, so when we use roller bearings, we should not only pay attention to other details, but also pay attention to the environment!
