Angular contact ball bearings installed in pairs

Paired angular contact ball bearings can bear radial load mainly radial and axial joint load can also be subject to pure radial loads. Tandem configuration can only bear axial load in one direction, the other two configurations can withstand axial load in either direction. After installing preload interference, rings and balls in the axial pre-load condition, thereby enhancing the entire group as a single bearing support stiffness and rotational accuracy.

Back to back configuration, the post Triple row roller slewing bearing code for the DB (eg 70000 / DB), back to back pairing separate line bearing load to the bearing axis. Can withstand the effect of axial load in both directions, but the load in each direction only by one bearing. Back to wind power bearings provide a relatively high rigidity of the bearing arrangement, and can withstand the overturning moment.
Face configuration, the post code for the DF (eg 70000 / DF), paired face-load line bearing the confluence of the bearing axis. Can withstand the effect of axial load in both directions, but the load in each direction only by one bearing. This configuration is better paired back to back with high rigidity, and is not suitable to withstand the overturning moments. This configuration of the rigid and affordability overturning moment is better than DB configurations, bearings can withstand axial load;
Series configuration, post code for DT (eg 70000 / DT), when arranged in series, parallel to the load line, radial and axial loads evenly shared by the bearing. However, acting on the bearing set can only bear axial load in one direction. If the Full complement cylindrical roller bearings axial load acting on the opposite direction, or if there is a composite load, it is necessary to increase a relatively tandem pair bearing adjustment third bearings. This configuration can also be a series of three or more bearings at the same support, but can only carry axial load in one direction. Generally, in order to balance, and to limit axial displacement of the shaft, to be installed at the other support in the other direction to withstand the axial load bearing.
