Higher angular contact ball bearing limiting speed, radial and axial load can also be subject to pure axial load, axial load capacity depends on its contact angle with the contact angle increases. Kind of bearing has the following three structural forms:

    Single row angular contact ball bearings separable type and can not be separated in two forms. S70000 type is the separation of type SN70000 type of inner separation type. Its inner and outer rings can be installed, the appropriate parts of the restricted installation conditions. The contact angle is 15. Non-separation of the angular contact ball bearings inner and outer rings can not be installed separately. The bearings are the following three basic structures: the contact angle a = 15 °, locking in the outer 70000C type contact angle a = 25 °, locking in the outer 70000AC type contact angle a = 40 °, locking in the outer ring 70000B type.

    The ball bearing is inseparable bearing can withstand large radial and axial two-way joint loads and moment loads, you can restrict the shaft or housing to do bi-directional axial displacement than the single row angular contact ball bearings have better rigidity, contact angle is 30.

    QJ0000 type of pairs of semi-double semi-outer QJF0000 type, four point contact ball bearings separable type bearings, the contact angle of 35. In the no-load and pure radial load, the balls and rings is a four-point contact, there will be a two-point contact, can accommodate axial loads in the pure axial load, balls and rings. Bearings can also withstand the torque load, and has a single row and double row angular contact ball bearings. Only when the two-point contact, the bearing can be guaranteed to work.
