Paired Angular Contact Ball Bearings

In terms of performance, the core advantages of paired angular contact ball bearings are reflected in "coordinated load-bearing" and "convenient installation". First, **Flexible load adaptation**: Through different combinations, it can achieve bidirectional axial load-bearing (DB/DF), one-way heavy load (DT) or anti-overturning (DB) to meet the needs of diverse working conditions; Second, **Controllable stiffness and accuracy**: The preload adjustment has been completed before leaving the factory, and the radial runout and axial clearance of the bearings in the group are not affected by errors. The difference is controlled within 0.005mm, and the rotation accuracy of the assembled equipment is 30%-50% higher than that of a single set; thirdly, **Simplified installation process**: There is no need to adjust the relative position and preload force of the two sets of bearings on site, and they can be installed directly according to the positioning benchmark, which greatly reduces the dif…
