Products Details
Angular contact ball bearings have raceways in the inner and outer rings that are offset in relation to each other in the direction of the bearing axis. These bearings are designed to accommodate combined loads and reach high speeds. The contact angle α is defined as the angle between the line joining the contact points of the ball and the raceways in the radial plane, and a line perpendicular to the bearing axis. The load carrying capacity of angular contact ball bearings increases with the increasing of contact angle. Angular contact ball bearings are generally used in pairs or even more with spacers.
Single row and combined angular contact ball bearing:
The standard contact angle is 15°,25°, and 40° respectively configuring in post position with code "C", "AC" and "B".
The more contact angle is, the larger the axial load bearing capacity is, the smaller the contact surface is, and the much more convenient the high-speed rotary is.
Pretension is made on angular contact ball bearing to increase rigidity and accuracy of bearing.
This bearing creates axial thrust load when being forced by radial load, thus it is configured (or combined)face to face or back to back.
Double row angular contact ball bearing:
Double row angular contact ball bearing can be submitted radial and axial loading limit speed is quite high, it is a non-separated type of bearings compare with the single row angular contact ball bearing the double row angular contact ball bearing has high rigid can be submitted doubt direction of axial load, the bearing could apply with the four-row cylindrical bearing together to limit the working roll to move in the axial direction the double row angular contact ball bearing could apply with other bearings as a position bearing.
Four-point contact ball bearing:
The standard structure is that its inner ring is equally divided in the axial direction, which is applicable to axial load or combined load, among which axial load is the major component.
A single bearing can bear double row axial load and certain extent radial load. According to different directions of axial load, the ring and sphere are always in contact at two points of the linear line.
