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.
