In a bid to offer fast rotary movements in compact applications and similar applications, igus has developed a new slewing ring bearing range for medium loads. These slewing rings are maintenance-free and wear-resistant and are manufactured using high-performance polymers. They are also 50 per cent smaller in installation height and 60 per cent lighter, saving the user up to 20 per cent of his costs.

These slewing rings are very much in demand at applications like high cycle rates and loads, for example, in welding systems, indexing tables or the packaging industry. In order to withstand this, igus has been offering slide-supported 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, igus 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, in sorting systems as well as in control panels or even in stage and lighting technology. In addition, thanks to the new slim type, the user saves 20 per cent of his costs.

 

The new PRT-04 range is available directly from stock with inner diameters of 50 to 300 millimetres. In addition, igus offers a wide range of accessories for the 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 the company's 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.
