Tapered roller bearings have conical inner and outer raceways, with tapered rollers arranged between them. The projection lines of all conical surfaces converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) loads. The contact angle α mostly determines the axial load capacity of the bearing; the larger the α angle, the higher the axial load capacity. The calculation coefficient e expresses the size of the angle; the larger the value of e, the larger the contact angle, and the greater the suitability of the bearing for bearing axial loads.

Tapered roller bearings are usually of the separable type, that is, the tapered inner ring assembly consisting of an inner ring with a roller and cage assembly can be installed separately from the tapered outer ring (outer ring).

Tapered roller bearings are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries.

The main reason for the occurrence of scars on tapered roller bearings during installation is: the inner ring and outer ring of the bearing are skewed during installation and assembly; or the impact load during installation and assembly may cause scars on the bearing. .

When installing tapered roller bearings, work standards must be followed. Otherwise, many problems will occur. If the installation mode or method is improper, linear scars will appear on the raceway surface and girdle surface of the bearing. The installation of deep groove ball bearings directly reflects the precision, service life and performance of the bearings in use.

Although the quality of tapered roller bearings and other aspects are relatively good, rolling bearings are precision components and their use must be carried out with corresponding caution. No matter how high-performance bearings are used, if used improperly, the expected high performance will not be achieved.

There are several things to note about the use of bearings:

(1) Keep the tapered roller bearing and its surroundings clean. Even small dust invisible to the eyes can have a bad impact on bearings. Therefore, it is necessary to keep the surrounding area clean so that dust does not invade the bearing.

(2) Use with caution. If the tapered roller bearing is subjected to strong impact during use, scars and indentations will occur, which may cause accidents. In severe cases, cracks and breaks may occur, so care must be taken.

(3) Use appropriate operating tools. Avoid replacing existing tools and use appropriate tools.

(4) Pay attention to the corrosion of tapered roller bearings. When operating bearings, sweat on your hands can cause rust. Be sure to use clean hands and wear gloves if possible.
