Angular Contact Ball Bearings (7212c, 7212AC, 7212 B)
Angular contact ball bearings can bear radial load and axial load at the same time.Can work under high speed.The larger the contact Angle, the higher the axial bearing capacity.High precision and high speed bearing contact Angle usually take 15 degrees.Under the effect of axial force, the contact Angle increases.
Angular contact ball bearing precision grade includes dimensional tolerance and revolving tolerance.From low to high precision is expressed as P0 (ordinary), P6 (P6X), P5, P4, P2.In addition, in the European and American brands also expressed in P3, P7 and P9 precision grade, P3 level equivalent to ISO and JIS standard P6, P7 is equal to the P4 level, P9 level equal to P2.
