iglidur® slewing ring, PRT-04, felt cover for PRT slewing ring bearing

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. 

The PRT-04 is the higher performer in our product range. In addition, you will benefit from an extensive and ever-growing modular system. 

• 60% lighter, 50% more compact and 20% more cost-effective than PRT-01
• Universal sliding elements made of iglidur® J
• Extensive modular system
• Particle emission test in Fraunhofer IAF-compliant cleanroom laboratory

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 good chemical resistance.

Do you have a cleanroom application?
With our iglidur® J sliding elements, you can also use the PRT-04 in the cleanroom. 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.
