7209AC High Precision Angular Thrust Bearing Contact Ball Bearing 45x85x19mm

72 Series High Precision Angular Contact Ball Bearing 7209AC Bearing Size 45*85*19mm

Description:

There are several types of angular contact ball bearings: 7000C (∝=15°), 7000AC (∝=25°) and 7000B (∝=40°). The lock of this kind of bearing is on the outer ring. Generally, the inner and outer rings cannot be separated, and can bear the combined radial and axial load and the axial load in one direction. The ability to bear the axial load is determined by the contact angle. The larger the contact angle, the higher the ability to bear the axial load. This kind of bearing can limit the axial displacement of the shaft or housing in one direction.
The contact ball bearing has a high limit speed and can bear radial load and axial load at the same time, and it can also bear pure axial load. Its axial load capacity is determined by the contact angle and increases with the increase of the contact angle.

Single row angular contact ball bearings
Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, additional axial force will be caused and corresponding reverse load must be applied. Therefore, this kind of bearings are generally used in pairs. Double row angular contact ball bearings can withstand larger radial and axial bidirectional combined loads and moment loads, mainly radial loads. It can limit the axial displacement of the shaft or housing in both directions, with a contact angle of 30 degrees.

Angular contact ball bearings installed 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 increasing 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 converge toward 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 it 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;
Tandem configuration, the post code is DT (such as 70000/DT), in tandem 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.
