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.
