Angular Contact Ball Bearings can bear radial load and axial load at the same time. Also can work at high speed. The larger the contact angle, the higher the axial bearing capacity. The contact angle is the angle between the line of contact points between the ball and raceway in the radial plane and the vertical line of the bearing axis. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.
Install angular contact ball bearings in pairs
Angular contact ball bearings installed in pairs can withstand combined radial and axial bidirectional loads based on radial loads, as well as pure radial loads. The series configuration can only bear axial load in a single direction, and the other two configurations can bear axial load in either direction. This type of bearing is generally selected and combined by the manufacturer and submitted to the user in pairs. After installation, there is preload interference, and the ring and steel ball are in the axial preload state, thus improving the rigidity and rotation of the entire group of bearings as a single support Accuracy.
Back-to-back configuration, the rear code is DB (such as 70000/DB), the load line of the back-to-back paired bearings is separated to the bearing shaft. It can bear the axial load acting in two directions, but the load in each direction can only be borne by one bearing. Bearings mounted back-to-back provide a relatively rigid bearing configuration and can withstand overturning moments.
Face-to-face configuration, the rear code is DF (such as 70000/DF), and the load lines of the face-to-face paired bearings merge to the bearing shaft. It can bear the axial load acting in two directions, but the load in each direction can only be borne by one bearing. This configuration is not as rigid as the back-to-back pairing and is not suitable for withstanding overturning moments. The rigidity and ability of bearing overturning moment of this configuration are not as good as the DB configuration, and the bearing can bear bidirectional axial load;
In series configuration, the post code is DT (such as 70,000/DT). In series configuration, the load lines are parallel, and the radial and axial loads are evenly shared by the bearing. However, the bearing assembly can only bear axial loads acting in one direction. If the axial load acts in the opposite direction, or if there is a compound load, a third bearing adjusted relative to the tandem paired bearing must be added. This configuration can also be connected in series with three or more bearings at the same support, but it can only withstand unidirectional axial loads. Generally, in order to balance and limit the axial displacement of the shaft, a bearing that can withstand the axial load in the other direction needs to be installed at the other support.
