7000 series Angular contact ball bearings are available in 7000C (∝=15°), 7000AC(∝=25°) and 7000B(∝=40°) types. The lock of this kind of bearing is on the outer ring. Generally, the inner and outer rings cannot be separated, and can bear the combined load of radial and axial directions and the axial load in one direction. The ability to withstand axial loads is determined by the contact angle, and the greater the contact angle, the higher the ability to withstand axial loads. This type of bearing limits the axial displacement of the shaft or housing in one direction. 7000 series are Single-row angular contact ball bearings, which are self-retaining units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet metal or brass cages.

7000 series Angular contact ball bearings accuracy grades include dimensional tolerances and rotational accuracy. The accuracy is expressed from low to high as P0(normal), P6(P6X),P5, P4 and P2. In addition, European and American brands also use P3, P7, P9 to indicate the accuracy level.

Application

This bearing series are usually used in machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shafts and so on.
