The first digit indicates the width or height series (dimensions B, T or H). The second digit identifies the diameter series (dimension D).
What is matched bearing?
Matched Pair bearings are Angular contact ball bearings that are suitable for applications that require high accuracy and high-speed performance. Bearings with a smaller contact angle are more suitable for high-speed rotation; those with a larger contact angle are more suitable for high load applications.
What does bearing code 22320k?

|Faces of bearing are kept separate by magnets (electromagnets or eddy currents)
What does C mean on a bearing?
The C code of the bearing indicates how much internal clearance the bearing gets in the machine. Your choice is crucial to prevent your bearings from having too much internal clearance. The size of the internal bearing clearance largely determines the operational performance of the bearings.
What are duplex bearings?
Duplex bearings are a pair of angular contact RBC Thin Section Ball Bearings specially ground for use as a matched set. A duplexed pair can be used to provide accurate shaft location, to increase capacity or to increase stiffness of the bearing assembly.
