CA can be common paired single row angular contact ball taper roller bearing  With this letter bearing can be arbitrarily paired back to back , face to face or in the same direction in series. In back to back or face to face , the bearing group has a small amount of axial internal clearance .
CB can be common paired single row angular contact ball bearings, bearing with this code can be arbitrarily paired back to back , face to face or in the same direction in series. In back to back or face to face , the bearing group axial internal clearance greater than CA.
CC can be universal paired single row angular contact ball bearings, with such suffixes can choose any two bearings , paired back to back or face to face configuration . Install the rear bearing manufacturer set with a light preload .
