R8LLU/5K bearing reference breakdown

Below we will break down the R8LLU/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 prefix can be found at the beginning of the bearing code:


R - Denotes the bearing is measured in imperial dimensions

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


LLU - Indicates a nitrile double lip contact seal
5K - Denotes universal grease for sealed and shielded bearings (-40°C up to +150°C)

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