Angular contact ball bearings can support radial and axial loads. To work at a high speed, the larger the contact angle, the higher the axial load capacity. The high-precision and high-speed bearings usually take the contact angle of 15 degrees. Axial force, the contact angle increases. Single row angular contact ball bearings can only support axial loads in one direction, in bear radial load, will cause additional axial force. And can only limit the axial displacement of the shaft or housing in one direction. If pairs of double installation, the bearing outer ring relatively wide end face of wide and narrow end facing the narrow end. This can avoid additional axial force, and the shaft or housing to limit the range of the axial clearance in both directions.
Angular contact ball bearings because of its raceways of the inner and outer rings relative displacement in the horizontal axis, so it can support radial and axial loads - combined load (single row angular contact ball bearings can only support a single direction axial loadSo often installed in pairs).
Retainers are made of brass, synthetic resin, etc., depending on the bearing forms, conditions of use and distinguish.
Angular contact ball bearing: 7000C-type (α = 15 °), of 7000AC type (α = 25 °) and 7000B (α = 40 °) several types. In the outer ring of the bearing locking inside and outside the ring can not be separated, can withstand radial and axial joint load and axial load in one direction. Axial load capacity is determined by the contact angle, the contact angle is large, is subjected to a high axial load capacity. This kind of bearing shaft or housing to limit axial displacement in one direction.
