Axial angular contact ball bearings for screw drives are single, double or triple row precision bearings. Depending on the series, they can support radial forces as well as axial forces in one or both directions. The bearing rings are matched to each other such that a defined preload is achieved when the rings are clamped in place using a precision locknut. Contact seals protect the rolling element system against contamination and moisture. For higher speeds, gap seals can be used.
Types:
-
single row axial angular contact ball bearings: 7602, 7603, BSB
-
double row axial angular contact ball bearings: ZKLN, ZKLF
-
triple row axial angular contact ball bearings: DKLFA.
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 then no need for the locating bore that would otherwise be required or for the bearing cover with the associated matching work.
For many applications, a bearing arrangement of lower precision is often sufficient. For this purpose, bearings with less stringent tolerances are available.
Screw drive bearing arrangements are subjected to requirements that often cannot be optimally fulfilled by the design construction of conventional bearings.For the design of bearing arrangements for the highly dynamic operating conditions in screw drives that have high accuracy, high load carrying capacity, high rigidity, low friction, are easy to fit and maintenance-free or low-maintenance, there is a wide range of axial angular contact ball bearings. With this product range, solutions can be found to all the technical and economic demands placed on the bearing arrangements of screw drives.
