7019UCG/GNP42U3G bearing reference breakdown
Below we will break down the 7019UCG/GNP42U3G 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 body of the bearing reference is what is left after removing the suffix and the prefix:
