7001UCG/GNP42 bearing reference breakdown

Below we will break down the 7001UCG/GNP42 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:


U - Ultage series
C - Indicates a contact angle of 15°
G - Indicates a universal bearing
GN - Indicates preloads (Light, Normal, Medium, Heavy)
P42 - Dimensional Accuracy of JIS Class 4, Running Accuracy of JIS Class 2

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