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,MONTON 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.
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.
