New compact igus slewing ring bearings for medium loads

Slewing ring bearings used in automation, stage
technology or control panels must allow for fast rotary movements in a small
space. For such compact applications, igus has now developed a new slewing ring
bearing range for medium loads. The slewing rings are not only maintenance-free
and wear-resistant, thanks to the use of high-performance polymers, they are
also 50 percent smaller in installation height and 60 percent lighter, saving
the user up to 20 percent of cost.

High cycle rates and loads, for example, in welding
systems, indexing tables or the packaging industry, are extremely demanding for
slewing rings. In order to withstand this, Treotham has been offering
slide-supported igus slewing ring bearings in its product range for 15 years.
The iglidur polymer slewing ring bearings (PRT) have sliding elements between
the inner and outer bearing rings made of aluminium or stainless steel. The
maintenance-free sliding elements made of high-performance iglidur J plastic
ensure that friction and wear are minimised without the use of lubrication. The
high-performance plastic withstands a maximum surface pressure of 35 MPa.

In addition, Treotham has FDA and ESD-compliant
versions with no minimum order quantity. igus has now developed the new PRT-04
range so that users can use slewing ring bearings even in compact installation
spaces with medium loads. Up to 50 percent space and the moving mass can be
significantly reduced by using this compared to the PRT-01 series with a 100-millimetre
inner diameter. Even compact applications can be implemented, for example, in
automation technology, sorting systems as well as control panels or even in
stage and lighting technology. In addition, thanks to the new slim type, the
user saves 20 percent of their costs.

variety: different sizes and accessories

The new PRT-04 range is available directly from stock
with inner diameters of 50 to 300 millimetres. In addition, Treotham offers a
wide range of accessories for slewing ring bearings from drive pin, variable
rotation limit and toothed ring up to the clamping lever. The new slewing ring
bearings have also demonstrated their long service life in igus’ own
3,800-square-metre test laboratory. The data collected in the tests are
incorporated in the iglidur PRT slewing ring configurator, which allows the
customer to quickly select the correct slewing ring bearing as well as
calculate the service life in the individual application.
