6815LLU/5K bearing reference breakdown
Below we will break down the 6815LLU/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:
