7204.BGA bearing reference breakdown
Below we will break down the 7204.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:
Suffix
A - Which indicates a single row angular contact ball bearing, with a polyamide cageBG - 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:
