Product Details
Angular contact ball bearings Angular contact ball bearing has high limit rotational speed, they can carry radial load and axial load simultaneously, they can also withstand purely radial load. The axial load carrying capacity depends on the magnitude of contact angle and increases with increasing contact angle. Structures 1. Non-separable angular contact ball bearings This inner ring and outer ring of this type of bearings cannot be separated and comprises following structures: Contact angle ?=15° counter bore on outer ring,7000Ctype Contact angle ?=25° counter bore on outer ring,7000ACtype Contact angle ?=40° counter bore on outer ring, 7000B type 2. Four-point contact ball bearings This type of bearings is separable bearings. Whereof, QJ0000 type has two-piece inner ring and QJF0000 type has two-piece outer ring. Their contact angles are same as 35°.When received no load or pure radial load, the steel balls of the ball bearing contact with the four points of the rings. When it is received a pure axial load, the steel balls perform a two-point contact with the ring. In addition, besides the axial load from both directions, this kind of bearing can take torque-load as well. 3. Double row angular contact ball bearings This kind of bearings can accommodate radial loads as well as axial loads acting in both directions; they can also take loading moment. They can restrain the axial displacement from both directions of the shaft or housing; the contact angle is 30° (or 40°) Permissible tilt angle There is only a little inclination between the inner ring and outer ring of angular contact bearings, the permissible tilt angle varies according to the internal clearance when the bearings are operating, the bearing dimensions, internal design, force and loading moment received by the bearings. The value of the maximum permissible tilt angle should be able to ensure tha
