PRT slewing ring bearings

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.  

Would you like more information about slewing ring systems or do you need an individual consultation? Our experts will be happy to get in touch with you.
