The inner bore of FAG self-aligning ball bearing could be cylinder or tapered,and the bearing can not be splitted.This kind of bearin is double row bearing which comprising sphere outer raceway .Its self-aligning ability can make up to the error,deformation of axial and deformation of bearing housing.
The inner bore of l2, l3, 22, 23 Series Self-Aligning Ball Bearings can be cylinder ortapered.The self-aligning bearing whose inner bore taper is 1:12 (code suffix K) can installed directly to the cone axis,also can  be set on cylindrical shaft through adapter sleeve. Besides providing non-sealed self-aligning ball bearings , FAG also can provide the basic types of self-aligning bearing with shield in two teminals. (code suffix .2 RS)
After heat treatment,the operating temperature of FAG self-aligning ball bearing can up to 150 degrees. The bearing which take the nylon cage should pay attention to the cage materials'limit to the work temperature.
