Spherical Roller Bearing

The self-aligning roller bearing features two rows of rollers, with one common spherical raceway on the outer ring and two raceways on the inner ring that are inclined at an angle relative to the bearing axis. This ingenious design gives it the ability to automatically align itself, thus being less susceptible to errors caused by the angle between the shaft and the bearing housing or the shaft's bending. It is suitable for applications where installation errors or shaft deflection result in angle errors. This bearing can not only withstand radial loads but also bidirectional axial loads.

The inner hole of the self-aligning roller bearing has two types: cylindrical and conical. The conical hole has a taper of 1:30 and 1:12. This conical inner hole bearing, when paired with a locking sleeve or a disassembly sleeve, can conveniently and rapidly assemble the conical inner hole onto a smooth shaft or a stepped machine shaft.
