Angular Contact Ball Bearing

Angular contact ball bearing (Angular Contact Ball Bearings) may also bear radial load and axial load. Can work at higher speeds. Contact angle decreases, the higher the axial load capacity. High precision and high-speed bearings usually take the contact angle of 15 degrees. In the axial force, the contact angle will increase. Single row angular contact ball bearings can only support axial load in one direction, the bearing radial load, will cause additional axial force. And the shaft or housing can limit the axial displacement in one direction. If pairs of double-install, make a pair bearing the outer ring relative, that is, wide-side end face of wide and narrow side face the narrow end. This can avoid additional axial force, but also in both directions to limit shaft or housing within the axial clearance.

Angular contact ball bearing raceway for its inside and outside the circle in the horizontal axis can have relative displacement, so able to support radial load and axial load - combined load (single row angular contact ball bearings can only support a single direction axial load So often adopted installed in pairs).

Cage made of brass, synthetic resins, etc., subject to individual bearing features and application conditions.

Angular contact ball bearings: 7000C-type (α = 15 °), 7000AC-type (α = 25 °) and 7000B (α = 40 °) of several types. The kinds of bearings in the outer ring on the lock mouth, usually inside and outside the ring can not be separated, can be combined radial and axial load and axial load in one direction. Axial load capacity of the decision by the contact angle, contact angle is larger, the ability to withstand high axial loads. This kind of bearing shaft or housing to limit axial displacement in one direction.

Higher speed limit contact ball bearings can support radial load and axial load, it can take pure axial load, axial load capacity of its decision by the contact angle, and with the contact angle increases.

Single row angular contact ball bearings can only support axial load in one direction, the radial load to bear, it will cause additional axial force must be applied to the corresponding reverse load, therefore, the types of bearings are generally used in pairs. Double row angular contact ball bearings can withstand greater radial load mainly to the radial, two-way co-axial load and moment loads, it limits bi-axial displacement of shaft or housing, the contact angle of 30 degrees.

Angular contact ball bearings installed in pairs in order to withstand the radial load mainly radial, two-way co-axial load can also be pure radial load to bear. Series configuration can only afford a single direction axial load, the other two configurations can withstand axial load in either direction. This type of bearings are generally submitted in pairs manufacturers matching combination of users, after installation preload interference, rings and balls in the axial pre-load state increases, thus increasing the entire group as a single bearing support stiffness and rotation accuracy.

Angular contact ball bearing main purposes:

Single row angular contact ball bearings: machine tool spindles, high frequency motors, gas turbines, centrifuges, small car front, differential pinion shaft

Double row angular contact ball bearings: oil pump, Roots blower, air compressor, various types of transmission, fuel injection pumps, printing machinery
