The features or self-aligning ball bearing
1. Bearings with general assembly
General distribution group of bearing is through special processing, when the bearing is installed close to each other, any combination can be established internal clearance or preload, and average load distribution, without having to use gaskets or similar device.
Paired bearings used in: when a single bearing load bearing capacity is insufficient configuration mode (using the channeling al) or when the bear joint load or effect of the axial load in both directions (use back to back or face-to-face way configuration).
2. The bearing of the basic design (which cannot be used for general assembly) is used for the configuration of a single bearing.
The basic design of single row angular contact ball bearings is mainly used in each position only one bearing configuration. Its width and prominence are common grade tolerances. Therefore, it is not suitable to install two single row angular contact ball bearings close to each other.
