Spherical roller bearings 21310CC/W33 CA/W33
Dimension:50*110*27
Once ordered, please inform me which type you need? .... thanks.
Spherical roller bearings have double-row rollers, with a common spherical raceway in the outer ring and 2 raceways in the inner ring and inclined at an angle with respect to the bearing axis. This ingenious structure makes it self-aligning, so it is not susceptible to the influence of the angle between the shaft and the bearing housing on the error or the bending of the shaft. It is suitable for the occasion of angle error caused by installation error or shaft deflection. In addition to being able to withstand radial loads, this bearing can also withstand axial loads acting in both directions.
Spherical roller bearings have cylindrical and conical inner bores. The conical taper bore taper is 1:30 and 1:12. This conical bore bearing is equipped with an adapter sleeve or a withdrawal sleeve. The self-aligning ball bearing with tapered inner hole can be easily and quickly assembled on the optical axis or the stepped shaft.

The tapered bore spherical roller bearings with the rear code names K and K30 are installed on the matching adapter sleeves, and then become the post code K + H and K30 + H bearings. This type of bearing can be installed on an 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 lubrication performance of the bearing, the bearing outer ring tank car three drill hole and evenly distributed, then set code of W33
