I believe that you are not unfamiliar with roller bearings. Roller bearings mainly rely on the rolling contact between the parts to support the rotating parts, so different roller bearings bear different axial and radial forces, so the environment used is different. Roller bearings have a great impact.
Selecting the gauge size and accuracy according to the use location, use conditions, and environmental conditions, and matching the appropriate bearing is the premise to ensure the life and reliability of the angular contact ball bearing. Angular contact ball bearings are suitable for bearing combined radial and axial loads mainly based on radial loads. They are usually used in pairs with two sets of bearings. They are mainly used in the front and rear hubs of automobiles, driving bevel gears, differentials, reducers, etc. transmission parts.
Under the environment of correct installation and good lubrication, it is allowed to be 0.3-0.5 times the limit speed of the bearing. Under normal circumstances, 0.2 times the limit speed is appropriate. Taper roller bearings generally do not allow the shaft to be inclined relative to the housing hole, if there is an inclination, it should not exceed 2'.
Under normal load, and the lubricant has high-temperature resistance and sufficient lubrication, the general angular contact ball bearing is allowed to work at an ambient temperature of -30°C to 150°C. The above are the effects of the use environment on the roller bearings, and they must be used as required.
To sum up, the environment has a great impact on the use of roller bearings, so we should not only pay attention to other details when using roller bearings but also pay attention to the environment!
