Spherical roller bearing

Spherical roller bearings have double row rollers, the outer ring has a common spherical raceway, the inner ring has two raceways and is inclined at an angle relative to the bearing axis. This ingenious structure makes it have automatic centering performance, so it is not easy to be affected by the angle of the shaft and the bearing box seat or the bending of the shaft. It is suitable for the installation error or the deflection of the shaft. The bearing can not only bear radial load, but also can bear two-way axial load.

Spherical roller bearing

Spherical roller bearings have two kinds of inner holes: cylindrical and conical. The taper of conical taper hole is 1:30 and 1:12. This conical inner hole bearing is equipped with a set sleeve or a withdrawal sleeve. The conical inner hole self-aligning ball bearing can be easily and quickly assembled on the optical axis or stepped crankshaft.
The types of self-aligning roller bearings are: self-aligning roller bearings (20000CC type); Tapered hole self-aligning roller bearings (20000CCK type); Spherical roller bearings (20000CC/W33 type); Tapered hole self-aligning roller bearings (20000CCK/W33 type); Self-aligning roller bearings (20000CCH type) 33 kinds of self-aligning roller bearings mounted on tightening sleeves
