Electric utility company igus offers lubrication-free slewing ring bearings from the polymer slewing ring bearings PRT-04 range, which saves 60% weight and 50% space, while performing fast rotary movements in a small space.

These are often the special requirements for slewing ring bearings in automation or stage technology as well as in control panels.

For such compact applications, the company explains that it has developed a new slewing ring bearings range for medium loads.

“The slewing rings are not only maintenance-free and wear-resistant, owing to the use of high-performance polymers, the slewing rings are also 50% smaller in installation height and 60% lighter, saving the user up to 20% of their costs.

“The high cycle rates and loads in welding systems, indexing tables or the packaging industry, are extremely demanding for slewing rings,” says the company.

It adds that, to cater for this, igus has been offering slide-supported slewing ring bearings in its product range for 15 years.

The iglidur 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 ensures that friction and wear are minimised without the use of lubrication.

The company explains that the high-performance plastic withstands a maximum surface pressure of 35 MPa. In addition, igus has Food and Drug Administration- and ElectroStatic Discharge-compliant versions with no minimum order quantity.

It has now developed the new PRT-04 range to ensure that users can use slewing ring bearings even in compact installation spaces with medium loads. Up to 50% space and the moving mass can be significantly reduced by using this, compared with the PRT-01 series with a 100 mm inner diameter.

Even compact applications can be implemented, for example, in automation technology and in sorting systems, as well as in control panels or even in stage and lighting technology. In addition, owing to the new slim type, the user saves 20% on costs.

The new PRT-04 range is available directly from stock with inner diameters of 50 mm to 300 mm. 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 m2 test laboratory.
