Features & Benefits
Angular contact ball bearings are more suitable for high-speed running occasions, they could carry both radial load and axial load. the axial load carrying capacity is related to the contact angle. The larger the contact angle, the greater the axial load that can be carried. The limiting speed of angular contact ball bearings is higher than other types of bearings of the same size. They are usually used in pairs, because they bear the effect of radial load and also produce axial force components. When working, the angular contact ball bearing can eliminate the internal clearance of the angular contact ball bearing due to the axial load after installation, which also relatively improves the rotation accuracy of the angular contact ball bearing.
