Rotational movement in a confined space; these are often the requirements for slewing ring bearings in automation or stage technology applications as well as in control panels. For such compact applications, igus has now developed a new ultra-slim slewing ring bearing range for medium loads. The PRT-04 slewing rings are maintenance-free and wear-resistant thanks to the use of high-performance polymers. Moreover, the new models are also 50 per cent thinner and 60 per cent lighter than standard PRT-01 bearings with a 100mm inner diameter.
High cycle rates and loads - for example, in welding systems, indexing tables or the packaging industry - are very demanding for slewing rings. To meet these requirements, igus has been offering sliding 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 iglidur J plastic, ensure that friction and wear are minimised without the use of lubrication. This high-performance plastic withstands a maximum surface pressure of 35MPa. In addition, FDA and ESD-compliant materials are available.
The new PRT-04 range is available directly from stock with inner diameters of 20 to 300mm. In addition, igus offers a wide range of accessories for the slewing ring bearings. These include a clamp lever, drive pin, variable rotation limit and toothed drive ring. By using the iglidur PRT slewing ring online configurator, engineers can quickly select the correct slewing ring bearing as well as calculate the service life for the specified application.
