Angular contact bearings should be installed in pairs
The main reasons for installing Angular Contact Ball Bearings in pairs are as follows:

The main reasons for installing Angular Contact Ball Bearings in pairs are as follows:
1. Bearing bidirectional loads: Single row angular contact
ball bearings can only withstand axial loads in one direction. When subjected to radial loads, additional axial forces will be applied, and corresponding reverse loads must be applied. Paired installation of angular contact ball
bearings can withstand combined radial and axial loads, mainly radial loads, as well as pure radial loads.
2. Improving motion stability: On some high-precision and bi-directional force bearing shafts, the motion process is complex, often with forward and reverse rotation, requiring rapid response and no axial movement when the shaft changes direction. Paired installation of angular contact ball bearings can prevent the shaft from shifting in two directions and achieve stable motion.
3. Limit axial displacement: If installed in pairs, it can make the outer rings of a pair of bearings face each other, that is, the wide end faces are opposite to the wide end faces, and the narrow end faces are opposite to the narrow end faces. This can limit the axial displacement of the shaft and improve the rotational accuracy of the shaft.
4. Improving bearing life: Paired installation of angular contact ball bearings can improve bearing life more than individual installation. Because paired installation can better balance the load of bearings, reduce bearing wear and fatigue.
5. Cost reduction: Although bearings installed in pairs may have a slightly higher unit price than individual bearings, considering the performance improvement and extended service life they bring, the overall cost is actually reduced.
In short, the paired installation of angular contact ball bearings is to meet specific engineering requirements, improve bearing performance and service life.
