7000UADG/GLP42 - NTN High Precision Angular Contact Ball Bearing
7000UADG/GLP42 bearing reference breakdown
Below we will break down the 7000UADG/GLP42 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
U - Ultage seriesAD - Indicates a contact angle of 25°
G - Indicates a universal bearing
GL - 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:
