PRT slewing ring bearings are ready-to-install slewing rings for lubrication-free, dry operations. The design is not based on metal rollers or balls but on maintenance-free sliding elements made of the proven tribologically optimised iglidur® materials. This is in combination with rings made of lightweight anodised aluminium or stainless steel. iglidur® materials can be employed universally and enable use in applications involving high temperatures, moisture or contact with chemicals, as well as in the food industry.
