Product description

Angular contact ball bearing have high limit rotational speed, they can carry radial load and axial
load simultaneously, they cal 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. Separable angular contact ball bearings
The 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, 7000C type
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, QJ000 type has two-piece inner ring and QJF000 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. Besides the steel balls perform a two-point contact with the ring when it is received a pure axial load. 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 torque-load. They can restrain the axial displacement from both directions of the shaft or housing; the contact angle is 30° (or 40°).
Cage material
Angular contact ball bearings generally adopt pressed steel cages or copper solid cages. Double-row angular contact ball bearings generally adopt copper solid cages.
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 and the force and torque-load received by the bearings. The value of the maximu
