6309.NR.ZZ bearing reference breakdown

Below we will break down the 6309.NR.ZZ 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:


ZZ - Denotes a shield on both sides
NR - Denotes a groove and snap ring on the outer ring

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