7064c/AC/B High-Speed Angular Contact Ball Bearings 320*480*74mm

7064c/AC/B High-Speed Angular Contact Ball Bearings 320*480*74mm

Angular contact ball bearings 7064C/AC/B are particularly suitable for carrying combined (axial and radial) loads.Their structures and properties vary according to their uses. Angular contact ball bearings for machine tool spindles require high rotation accuracy, sufficient stiffness, load-bearing capacity and small occupancy of space.

Single row angular contact ball bearings can only bear the axial load in one direction. When bearing the radial load, it will cause additional axial force, and can only limit the axial displacement of the shaft or shell in one direction. The contact angle of angular contact ball bearing is 40 degrees, so it can bear a large axial load. Angular contact ball bearing is a non-separable design, and the shoulders on both sides of the inner and outer rings vary
in height.
