How to install self align roller bearing correctly?

Self align roller bearing is a bearing equipped with drum rollers between the inner ring with two raceways and the outer ring with spherical raceways. The curvature center of the outer ring raceway surface is consistent with the bearing center, so it has the same centering function as the self-aligning ball bearing.

When the shaft and housing are deflected, the load can be adjusted automatically and the axial load in two directions can be adjusted automatically. Large radial load capacity, suitable for heavy load and impact load. The inner diameter of the inner ring is a self align roller bearing with a taper hole, which can be installed directly. Or use an adapter sleeve or a disassembly tube to install it on the cylindrical shaft. The cage uses a steel stamping cage, a polyamide forming cage and a copper alloy car cage.

For self-aligning bearings, the use of an intermediate mounting ring can prevent the outer ring from tilting and rotating when installing the bearing with the shaft into the box shaft hole. It should be remembered that some sizes of self-aligning ball bearings have balls protruding from the side of the bearing, so the middle mounting ring should be recessed to prevent damage to the balls. A large number of self align roller bearings are generally installed by mechanical or hydraulic press-in method.

For the separable self align roller bearing, the inner ring and the outer ring can be installed separately, which simplifies the installation process, especially when the inner and outer rings require interference fit. When installing the shaft with the inner ring in place into the bearing box that already contains the outer ring, care must be taken to check whether the inner and outer rings are correctly aligned to avoid scratching the raceways and rolling parts of the self align roller bearing. If cylindrical and needle roller bearings use inner rings without flanges or inner rings with flanges on one side, it is recommended to use mounting sleeves. The outer diameter of the sleeve should be equal to the inner ring raceway diameter F, and the tolerance standard for machining should be d10. Drawn cup needle roller bearings are best installed with mandrels.
