Single row angular contact ball bearings

Single row angular contact ball bearings

Angular contact ball bearing can carry radial load and axial load at the same time, meanwhile, it can also endure pure axial load, together with high limited speed. The carrying capacity of axial load is decided by the contact angle, the bigger contact angle, the higher carrying capacity of axial load. The definition of contact angle α Is the angle formed by the line upright with axes of bearings and the line which connect the grounders and contact of rollaway.

Single row angular contact ball bearings have following structure types:

(1) Divergence type angular contact ball bearings

The code name of such bearing is S70000, there's no fore shaft in outside track rollaway nest, and it can be separated with inside track, retainer, and steel balls these components, so that it can be installed separately. Such kind of bearings usually are mini type bearings whose internal diameter is less than 10mm, it is used in peg-top rotor, tiny electromotor and so on such equipment which have a high requirement of dynamic balance, noise, libration, stability.

(2) Non contact-type angular contact ball bearings

The ferrule channels of these bearings have fore shaft, so two ferrules can not be separated. According to the contact angle, it can be divided into 3 types:

Pairing configuration angular contact ball bearings mainly used in the occasion of stand both the axial load and radial load at the same time; Meanwhile, it can also endure pure radial load and axial load from any direction. The factories choose and pairs such bearings according to certain requirement of pre load, and then offer them to clients. After bearing is installed in the machines and fastened, there will be no windage in bearings absolutely, meanwhile, both ferrule and steel balls are in the condition of tightness, thus can improve of rigidity of combined bearings.
