Angular contact ball bearings can support radial and axial loads. Able to work at higher speeds. The contact angle, the higher the axial load carrying capacity. High-precision and high-speed bearings usually take 15-degree angular contact ball bearingsAngular contact ball bearingsIn the axial force, the contact angle will increase. Single row angular contact ball bearings can withstand axial load in one direction, while the radial load, will cause additional axial force. And the only limit axial displacement in one direction, the shaft or housing. If paired installation, so that one pair of bearing outer ring relative to that wide side face of wide and narrow side facing the narrow end. This can avoid additional axial force, and the shaft or housing to limit the axial clearance range in both directions.Angular contact ball bearing raceway for its inner and outer rings relative displacement on the horizontal axis, so it can bear radial load and axial load - combined load (single row angular contact ball bearings can withstand axial load in one direction, So often adopted installed in pairs).Cage made of brass, synthetic resins, etc., depending on the bearing forms, and application conditions.Angular contact ball bearings: 7000C type (α = 15 °), 7000AC type (α = 25 °) and 7000B (α = 40 °) types. bearing outer ring locking in the general inner and outer rings can not be separated, can withstand radial and axial joint load and axial load in one direction. Axial load capacity of a decision by the contact angle, the contact angle is large, the ability to withstand high axial loads. This kind of bearing can limit the axial displacement in a direction of shaft or housing.
The main purpose

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

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