Recently, I found that there are many inquiries about the application of angular contact ball bearings and double row angular contact ball bearings, as well as their respective advantages. Next, I will introduce them to you.
Many people will think of the fixing method of the ball screw. The ball screw bearing is that there are two parallel bearings installed here on the ball screw fixing seat, that is, the angular contact ball bearing. Compared with the deep groove ball bearing, the angular contact ball bearing is better at bearing the axial force in a single direction. However, the unique stress mode of the angular contact ball bearing leads to its installation method, which is generally used in pairs, For back-to-back or face-to-face installation, we use two angles in different directions to connect single row angular contact ball bearings to complete the axial force in both directions. Because if we only use one, when the ball screw receives the axial force in the other direction, the accuracy of the bearing will change and it is easy to be damaged. Therefore, we need to install two angular contact bearings in this case.
Another situation is that we only need to install one, that is, double row angular contact bearings. Two angular contact ball bearings are installed back-to-back in the same bearing ring. In fact, it is still two angular contact ball bearings from the middle; Its advantage is that compared with the two single row angular contact bearings, the width of the double row is relatively narrow, which saves space and is more convenient to use. Therefore, two angular contact ball bearings are installed back-to-back.
Many times, we can try to use double row angular contact ball bearings, which are load-bearing, or we can use them face-to-face.
