Roller roller bearings (1 row, 2 rows)

Roller roller bearings are generally used in working conditions with heavier axial loads. This type of bearing is composed of a ring-shaped grooved ring (shaft washer, seat washer), a cylindrical roller and a cage assembly. The cylindrical rollers are machined with convex surfaces so the pressure distribution between the rollers is uniform. It can bear a large unidirectional axial load, and the rigidity of the shaft is very strong. The bearings are designed to be flexible and can provide a variety of combinations according to the characteristics of the machine part in relation to the user. If the machine part has high precision and rigidity, the shaft ring and washer can be omitted, and the roller assembly and cylindrical cage can be installed directly. The cylindrical rollers are precision cut, thus avoiding edge stress concentration and making the load distribution uniform. The user can select the appropriate bearing according to the application. Lubrication method: oil lubrication method is applied. There are 1 row and 2 row roller bearings.

The international designation for spherical roller bearings usually has 5 main digits, starting with the number 8.
