6813LLB/5K bearing reference breakdown

Below we will break down the 6813LLB/5K 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:


5K - Denotes universal grease for sealed and shielded bearings (-40°C up to +150°C)
LLB - Denotes a nitrile non-friction seal

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