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 re-circulating components, but on maintenance-free sliding elements made of proven, tribologically optimised iglidur® materials in combination with rings made of lightweight anodised aluminium.

The felt cover was developed for applications in particularly harsh environments where high loads, dirt and dust occur, and prevents the ingress of dirt and dust into the PRT system. Abrasion can contribute to additional contamination, especially in highly dynamic applications.

The felt seal allows for a longer service life, especially in harsh environments, e.g. in the agricultural, construction and mining industries.
