1217KC3 bearing reference breakdown
Below we will break down the 1217KC3 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:
Suffix
C3 - Denotes a radial internal clearance of the C3 classK - 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:
