Recently, I have found that there are many inquiries about how angular contact ball bearings and double row angular contact ball bearings are used, and what their respective advantages are, so I will introduce them to you next.
Many people will think of the way the ball screw is fixed. The ball screw bearing means that there are two parallel bearings installed on the ball screw fixed seat, that is, the angular contact ball bearing. Compared with the deep groove, the angular contact ball bearing Ball bearings are better at withstanding axial force in a single direction, but the unique force-bearing method of angular contact ball bearings leads to their installation method. They are generally used in pairs, installed back-to-back or face-to-face. We use Two angles with different directions are connected to the single row angular contact ball bearing to complete the axial force in two directions, because if we only use one, when the ball screw receives the axial force in the other direction, The accuracy of this bearing will change and be easily damaged, so in this case we need to install two angular contact bearings.
Another situation is that we only need to install one, that is, a double-row angular contact bearing. Two angular contact ball bearings are installed back to back in the same bearing ring. In fact, when viewed from the middle, they are still two angular contact bearings. Ball bearings; its advantage is that compared to two single-row angular contact bearings, the double-row width is narrower, which saves space and is more convenient to use. It is equivalent to installing two angular contact ball bearings back to back.
We can often try to use double-row angular contact ball bearings, which are load-bearing bearings, or we can pair angular contact ball bearings face to face.
