6818LLB/2AS bearing reference breakdown

Below we will break down the 6818LLB/2AS 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:


2AS - Denotes standard grease for sealed and shielded bearings (-25°C up to +120°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:
