7210B.TVP Ball Bearing 7210B-TVP Angular Contact Bearing 50*90*20

7210B.TVP Ball Bearing Description:

Suffix meaning:
B: 40 degree contact angle
TVP: glass fiber reinforced polyamide type solid cage, steel ball guided
The greater the contact angle, the higher the ability to withstand the axial load.
For 7207B-TVP bearing, it is 40 degree contact angle angular contact ball bearing

Angular Contact Ball Bearing Precision:

The accuracy grade of angular contact ball bearing includes dimension tolerance and rotation accuracy.
The accuracy from low to high is expressed as P0 (normal), P6 (P6X), P5, P4 and P2.
In addition, European and American brands also use P3, P7 and P9 to express accuracy level.
P3 is equivalent to P6 level of ISO and JIS standard, P7 is equivalent to P4 level, P9 is equivalent to P2 level.
