Axial angular contact ball bearings are precision bearings for supporting screw drives. Depending on the series, they can support high radial forces as well as axial forces from one or both sides.
The inner ring is matched to the ball and cage assemblies and the outer ring. As a result, the bearings can be set to a defined axial preload. Contact seals protect the rolling element system against
contamination and moisture. For higher speeds, gap seals can be used.
The bearings are available with and without fixing holes in the outer ring. Bearings with holes are screw mounted directly on the adjacent construction. This solution is particularly economical since there is no need for the locating bore otherwise required or for the bearing cover with the associated matching work.
For applications in the handling sector, for woodworking machinery and transport type screw drives, a bearing arrangement with a lower level of precision is often sufficient. For this purpose, there are versions with less stringent tolerances.
