7312.BGA bearing reference breakdown

Below we will break down the 7312.BGA 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:


A - Which indicates a single row angular contact ball bearing, with a polyamide cage
BG - Which indicates a 40° contact angle, with a universal design

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