Features

Screw drive bearing arrangements are subjected to requirements that often cannot be optimally fulfilled by the design construction of conventional bearings. In order to design 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,  has a wide range of axial angular contact ball bearings. With this well thought-out product range, ideal application-specific solutions can now be found to all the technical and economic demands placed on the bearing arrangements of screw drives.

Multi-row designs Axial angular contact ball bearings are available as single, double or triple row ready-to-fit units. They are self-retaining and comprise thick-walled, geometrically stable outer rings, ball and cage assemblies and one-piece or two-piece inner rings. In several series, the outer ring has through holes for simple flange mounting to the adjacent construction. 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.

Radial and axial load carrying capacity Due to the 60° contact angle, the bearings can support high axial forces.

Double row axial angular contact ball bearings, for screw mounting Axial angular contact ball bearings ZKLF are screw mounted directly on the adjacent construction or in a radial locating bore, Figure 1 and Figure 2.

The cover that would otherwise be required and the associated matching work can therefore be dispensed with. In order to aid removal of the bearings from a locating bore, the outer ring has a circumferential extraction slot. Relubrication is facilitated by radial and axial threaded connectors with set screws.
