NU2306EG1C3 bearing reference breakdown

Below we will break down the NU2306EG1C3 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:


NU - Denotes a NU type single row cylindrical roller bearing

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


C3 - Indicates a radial internal clearance of the C3 class
E - Increased capacity
G1 - Brass cage

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