1222KC3 bearing reference breakdown

Below we will break down the 1222KC3 bearing reference and provide an explanation for each section provided it can actually be broken down. We can split it into 3 parts the prefix, suffix and body of the item code.

The suffix can be found at the end of the bearing number:


C3 - Denotes a radial internal clearance of the C3 class
K - Which indicates a tapered bore, taper 1:12

The body of the bearing reference is what is left after removing the suffix and the prefix:
