Spherical roller bearing installation

- Mar 31, 2018 -

Spherical roller bearings are equipped with a cylindrical roller bearing between the inner ring with two raceways and the outer ring with a spherical raceway. Since the center of curvature of the raceway surface of the outer ring is the same as the center of the bearing, it has the same centering function as the self-aligning ball bearing. When the shaft and housing are bent, they can automatically adjust the load and axial load in both directions. Radial load capacity, suitable for heavy load and impact load conditions. The inner diameter of the inner ring is a tapered bore bearing that can be mounted directly. Or use an adapter sleeve and a disassembly cylinder mounted on the cylinder shaft. The cage uses steel cages, polyamide cages and copper alloy cages.

For self-aligning bearings, an intermediate mounting ring is used to prevent the outer ring from tilting and rotating when the bearing and shaft are installed in the housing bore. It should be remembered that the balls of certain sizes of self-aligning ball bearings protrude from the sides of the bearing, so the intermediate mounting ring should be recessed to prevent damage to the ball. A large number of bearings are usually mounted using mechanical or hydraulic press-in methods.

For separable bearings, the inner and outer rings can be mounted separately, which simplifies the installation process, especially when the inner and outer rings require an interference fit. When the inner ring and the outer ring are installed together in the bearing housing, care must be taken to ensure that the inner ring and the outer ring are correctly centered so as not to scratch the bearing races and the rolling elements. If the inner ring used for cylindrical roller bearings and needle roller bearings does not have flange ribs or flanged inner rings, it is recommended to use a mounting sleeve. The outer diameter of the sleeve should be equal to the raceway diameter of the inner ring. The tolerance for machining tolerances should be d10. Needle roller bearing outer ring needle roller bearing is the best way to install.
