, universally matchable bearings

     Universally matchable bearings are specially processed, when the bearing is installed close to each other, any combination can achieve the established internal clearance or preload, and the average load distribution, without the use of shims or similar devices.
     Pairing bearing applications: When a single bearing load carrying capacity is insufficient (associated with channeling configuration) or when to bear the combined load or effect in both directions of the axial load (with back to back or face to face configuration).
     2, the basic design of the bearing (not as a general with the group), is configured for a single bearing
     Basic design of single Roller bearing contact ball bearings are mainly used in each location is only one bearing configuration. Its width and the amount of outstanding ordinary level tolerances. Therefore not suitable for the two single row angular contact ball bearings close to the installation
