Many of our customers will ask how angular contact ball bearings and double row angular contact ball bearings are used and what their respective advantages are. The editor will introduce them to you next. Many people will think of the fixing method of the ball screw. The ball screw bearing is that there are two parallel bearings installed on the ball screw fixing seat, that is, the angular contact ball bearing. Compared with the deep groove, the angular contact ball bearing Ball bearings are better in bearing axial force in a single direction, but also because of the unique force method of angular contact ball bearings, its installation method is generally used in pairs, back-to-back or face-to-face installation, we use Two angles in 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, from the middle section, they are still two angular contact. Ball bearing; its advantage is that compared with two single-row angular contact bearings, the width of double-row is relatively narrow, which saves space and is more convenient to use, which 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-type bearings, and can also be paired with angular contact ball bearings in a face-to-face form. The torque is accurate, in order to turn stable!
