Model Number: QJF 1038X1 M Brand Name: NXZ Key Specifications/Special Features: Angular contact ball bearingsAngular 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.Structures1、 Non-separable angular contact ball bearingsThis inner ring and outer ring of this type of bearings cannot be separated and comprises following structures:Contact angle α=15° counter bore on outer ring, 7000C typeContact angle α=25° counter bore on outer ring, 7000AC typeContact angle α=40° counter bore on outer ring, 7000B type2、 Four-point contact ball bearingsThis 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 that no much extra stress to be generated inside the bearings.
The tilt angle existing between the inner ring and outer ring will influence the bearing service lifespan. Meanwhile, the running accuracy is decreased down and noise increased.
Tolerance and clearance
The tolerances of general angular contact bearings are class normal P0, class P5 and P6. Class P4 and P2 are applicable to machine tool spindles and bearing amount in pairs.
Clearance of single row angular contact bearing is decided by the contact angle, which is guaranteed by manufacturing.
