Product description:

Angular contact ball bearings are able to support radial lode and axial lode. As single row angular contact ball bearings can only support axial lode in single direction, matched bearing mounting is often adopted to them. As matched pairs of bearing, preload for them is more convenient. Retainers are made of brass, synthetic resins or other subject to individual bearing features and application conditions.

Features:

1) Load capacities are higher than deep groove ball bearings of same dimensions

2) Used for bearing radial-axial combined loads or pure thrust loads

3) Low operating friction and high limiting speed

  An angular contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load. In high speed applications, such as turbines, jet engines, and dentistry equipment, the centrifugal forces generated by the balls changes the contact angle at the inner and outer race.

Angular contact ball bearings can bear not only axail but also radial loading capacity.Though only bearing unilateral axial loading capacity, they can be used together with the bearings bears opposite axial loading capacity. Angular contact ball bearings, with a limit ability to self-aligning, can not be dismantled.

 contact ball bearing details

Angular contact ball bearings are able to support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, matched bearing mounting is often adopted to them. As matched pair of bearings, preload for them is more convenient. Retainer are made of brass, synthetic resins or others subject to individual bearing features and application conditions.

1).Main structure

A. single-row angular contac ball bearing

     single-row angular contac ball bearing have separable and non-separable designs,such as          S7000  series and SN7000 series.

B. double-row angular contact ball bearing.

C. paired and match angular contact ball bearing

Angular contact ball bearing type:

Single row angular contact ball bearing: only carry a direction of the axial load, when in bear radial load, can cause additional axial force must be applied to the corresponding reverse load, therefore, the bearings are generally used in pairs.

Double row angular contact ball bearing: At the same time can bear radial and axial load joint load, limit shaft on both sides of the axial displacement.
