Slewing rings
For many years, INA has made a decisive contribution to the
development and current level of rolling bearing technology, particularly
through its compact needle roller bearings, high load capacity
cylindrical roller bearings and its diverse range of track rollers for rotary
and linear motion.
INA slewing rings are also known worldwide as premium products in
the field of rolling bearing technology. These machine elements have
proved themselves many times over; they have high load carrying
capacity, a versatile range of applications and are highly cost-effective.
Due to their design, a single bearing can reliably support radial,
axial and tilting moment loads. It is therefore possible in many cases
to replace bearing arrangements comprising a combination of radial
and axial bearings by a single bearing. This reduces, in some cases
considerably, the costs and work required in the design of the adjacent
construction and the fitting of bearings.
Slewing rings are sealed on both sides, lubricated with a high quality
grease, can be relubricated via lubrication nipples and are particularly
easy to fit. The bearing rings are supplied without gear teeth or,
in order to achieve simple drive solutions, are available with external
or internal gear teeth.
INA slewing rings are designed as:
■ four point contact bearings
– these slewing rings without preload are robust and proven
under very demanding operation; they place only slight demands
on the flatness and perpendicularity of the adjacent construction
– they are suitable for applications with low requirements for
accuracy and rigidity of the bearing arrangement, for example in
simple metalworking machines, wind power equipment and
construction machinery
■ crossed roller bearings
– these preloaded slewing rings can support higher loads than
four point contact bearings. They have proved themselves
particularly where bearings are subjected to high radial forces
and moderate axial and tilting moment loads
– they are suitable for applications with uniform running free from
stick-slip, low rotational resistance and high requirements for axial
and radial runout accuracy and rigidity, for example in robots,
handling systems and machine tools.
Catalogue 404 presented here gives comprehensive information
on the reorganised standard range of these slewing rings.
The catalogue has been completely revised and replaces

with the information is this edition is therefore invalid.
