Taper roller bearings are mainly subjected to radial and axial joint load, which is mainly radial load.The bearing capacity depends on the raceway angle of the outer ring, the larger the angle, the greater the bearing capacity. This type of bearing is a separable bearing and is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rolling elements in the bearing.

The clearance of single-row tapered roller bearings needs to be adjusted by the user during installation; the clearance of double-row and four-row tapered roller bearings has been given according to user requirements when the product leaves the factory and does not need to be adjusted by the user. Although taper roller bearings are better in terms of quality and other aspects, rolling bearings are precision components and their use requires caution. No matter how high-performance bearings are used, if they are not used properly, they will not achieve the expected high performance. Precautions for the use of bearings are as follows：

Even small dust that is invisible to the eye can have a bad effect on the bearings. Therefore, it is important to keep the surrounding area clean so that dust cannot invade the bearings.

A taper roller bearing is subjected to strong impact during use, which can produce scars and indentations that can lead to accidents. In severe cases, bearings can crack and fracture, so attention must be paid.

Avoid substituting existing tools for the correct tool; the appropriate tool must be used.

Selecting the gauge size, accuracy and matching the appropriate bearing according to the use location, use conditions and environmental conditions is the premise to ensure the life and reliability of the tapered roller bearings.

Tapered roller bearings is suitable for bearing radial and axial joint load, with radial load as the main. Usually used in pairs with two sets of bearings, mainly in the front and rear hubs of automobiles, active bevel gears, differentials, reducers and other transmission parts. Under the environment of correct installation and good lubrication, it is allowed to be 0.3-0.5 times the limiting speed of the bearing. In general, under normal circumstances, 0.2 times the limit speed is appropriate. Taper roller bearings generally do not allow the shaft relative to the shell hole tilt, if there is tilt, not more than 2 degrees.

Roller bearings in bear normal load, and the lubricant has high temperature resistance, and lubrication under the condition of adequate, general angular contact ball bearings are allowed to work in the ambient temperature of -30 ℃ -150 ℃. These are the use of the environment on the roller bearings caused by the impact, must be used in accordance with the requirements.

In summary, the environment has a great impact on the use effect of roller bearings, so when using roller bearings, we must not only pay attention to other details, but also pay attention to the environment.
