iglidur® PRT slewing ring bearings are ready-to-install slewing rings for lubrication-free, dry operation. The design is not based on metallic rollers or balls, but on maintenance-free sliding elements made of the proven tribologically optimised iglidur® materials in combination with rings made of lightweight anodised aluminium.

Instead of the through holes as found in the standard version of the PRT-04 series, an M4 thread has been drilled into the outer ring. This provides you with additional mounting options.

60% lighter, 50% more compact and 20% more cost-effective than PRT-01

The sliding elements made of iglidur® J are our best all-rounders. They are characterised by a low coefficient of friction during dry operation. Furthermore, this material has a low moisture absorption and offers a good chemical resistance.

Do you have a cleanroom application? With our iglidur® J sliding elements, you can also use the PRT-04 in cleanrooms. Please contact us if you require further advice or information.Get an overview on our website or in the catalogue or have a look at our Online seminar on the PRT-04 modular system.
