Do you know the right way angular contact ball bearing mounting of it?

Angular contact ball bearing mounting is more complex than deep groove ball bearings, mostly in pairs and requires preloading. The installation is good, the working accuracy and bearing life of the main machine can be greatly improved; otherwise, the accuracy will not meet the requirements and the service life will be affected.

Pairs angular contact ball bearing mounting can withstand radial and axial bidirectional combined loads, mainly radial loads, and can also withstand pure radial loads. The tandem configuration can only withstand axial loads in one direction, while the other two angular contact ball bearing mounts can withstand axial loads in either direction. This type of bearing is generally selected by the manufacturer and combined into a pair of users. After the angular contact ball bearing is installed, the ferrule and the steel ball are in the axial preload state, thus improving the whole set of bearings as a single Support stiffness and rotation accuracy.

 Angular contact ball bearing mounting: back-to-back configuration, rear coded DB (eg 70,000/DB), the load line of the back-to-back matched bearing is separated from the bearing shaft. angular contact ball bearing mounting can withstand axial loads acting in both directions, but the load in each direction can only be absorbed by one bearing. Back-to-back angular contact ball bearing mounting provide a relatively rigid bearing configuration and can withstand overturning moments.

 Angular contact ball bearing mounting: The face-to-face configuration, rear codenamed DF (eg 70,000/DF), the load line of the face-to-face matched bearings meets the bearing shaft. It can withstand axial loads acting in both directions, but the load in each direction can only be absorbed by one bearing. This angular contact ball bearing mounting is not as rigid as a back-to-back pair and is not well suited to withstand overturning moments. The angular contact ball bearing mounting has the rigidity and the ability to withstand the overturning moment. The bearing can withstand biaxial axial loads.

 Angular contact ball bearing mounting: series configuration, rear coded DT (such as 70,000 / DT), in series configuration, the load line is parallel, radial and axial load is evenly shared by the bearing. However, the bearing set can only withstand axial loads acting in one direction. If the axial load acts in the opposite direction, or if there is a composite load, a third bearing that is adjusted relative to the series matched bearing must be added. This angular contact ball bearing mounting can also be used with three or more bearings in series at the same bearing, but can only withstand axial loads in one direction. Usually, in order to balance and limit the axial displacement of the shaft, the other bearing needs to be fitted with a bearing that can bear the axial load in the other direction.
