A Brief Introduction To Spherical Roller Bearings

Spherical roller bearings have double row rollers with 1 common spherical raceway on the outer ring and 2 raceways on the inner ring that are tilted at an angle relative to the bearing axis. This ingenious construction makes it self-aligning, so it is not susceptible to the influence of shaft and bearing housing angle errors or shaft bending, and is suitable for installation errors or shaft deflection caused by angle errors. In addition to radial loads, the bearings can also withstand axial loads acting in both directions.
Spherical roller bearings have cylindrical and conical bores, tapered bore taper of 1:30 and 1:12, this kind of tapered bore bearing with adapter sleeve or withdrawal sleeve, can be tapered bore self-aligning ball bearings conveniently and quickly assembled on the smooth shaft or stepped shaft.
