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 clever structure makes it have self-aligning performance, so it is not easy to be affected by the angle of the shaft and the bearing housing to the error or the bending of the shaft. In addition to the radial load, the bearing can also support axial load in both directions.

Spherical roller bearings have cylindrical and conical internal bores, and tapered cone bores have a taper of 1:30 and 1:12. This tapered inner bore bearing is equipped with an adapter sleeve or a withdrawal sleeve. The conical inner hole self-aligning ball bearing can be easily and quickly assembled on the optical axis or the stepper shaft.

Spherical roller bearings are divided into: cylindrical inner hole and conical inner hole.

When this type of bearing is with a tapered shaft, the inner ring moves in the axial direction to adjust the radial clearance of the bearing.

The tapered spherical roller bearings with rear code K and K30 are installed on the matching adapter sleeves, and then become the rear bearings K + H and K30 + H. This type of bearing can be installed on the optical axis without a shoulder, which is suitable for occasions where the bearing needs to be frequently installed and removed. In order to improve the lubricating performance of the bearing, there is an annular oil groove on the outer ring of the bearing and three oil holes are evenly drilled. The rear code is W33.
