Angular Contact Ball Bearing
Angular contact ball bearings are suitable for occasions that can bear both radial and axial loads. It can also be used in the occasion of bearing pure axial load and can work at higher speed. The ability of the axial load that bearing bears varies with the size of the contact angle.
-
① Single row angular contact ball bearing
Single row angular contact ball bearing can bear radial load and unidirectional axial load. The ball has a contact angle of 15 °, 25 ° or 40 ° with the inner and outer rings. The larger the contact angle is, the greater the bearing capacity of the axial load is. The smaller the contact angle is, the more favorable it is for high-speed rotation.② Double row angular contact ball bearing
The double row angular contact ball bearing has good rigidity, can bear two-way axial load, and can also bear certain overturning moment. Its application effect is similar to that of two single row angular contact ball bearings with back-to-back configuration and. Double row angular contact ball bearing consists of a outer ring and an inner ring (or two inner rings).③ Three (Four) points contact ball bearing
The three (four) point contact ball bearing is a single row angular contact ball bearing with double half inner ring or double half outer ring, which belongs to separable structure. This kind of bearing can bear bidirectional axial load and limit axial displacement in two directions. This kind of bearing has large bearing capacity because of the increase of the number of steel balls in the double half inner ring (or outer ring).Single row angular contact ball bearings can be configured in pairs or in multiple combinations (triple, quadruple or multiple combinations). When the angular contact ball bearings installed in pairs are installed close to each other, any combination method can achieve predetermined internal clearance and preload, as well as uniform load distribution. The angular contact ball bearing installed in pairs is mainly used when the load bearing capacity of single angular contact ball bearing is insufficient, or when bearing combined load in shaft (radial) direction and axial load in two directions. The angular contact ball bearings installed in pairs are provided with back-to-back, face-to-face and series configuration. -
