What are slewing ring bearings?

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

iglidur® materials are universally applicable and can be used at high temperatures, in contact with moisture or chemicals and in the food industry.

Application examples - slewing rings in real life

PRT-01 slewing ring bearing in the Linatronic from Krones

Krones AG relies on lubrication-free PRT slewing rings from igus®

The Linatronic 735 from Krones is used to check reusable bottles. Are there objects, smallest foreign bodies or lye residues in the bottles? Are there cracks in the glass or has something splintered? Are there dirt residues on the side? PRT slewing rings are used to open the Linatronic. They ensure lubrication and maintenance-free bearing points and make a significant contribution to hygienic design.

Personal robot

When upgrading a customer robot, an iglidur PRT slewing ring was incorporated in the axis for the first time. An iglidur PRT-02-20 is now used in the rear axis of the robot. In order to optimally meet the requirements of EEVE, igus designed a custom solution with reduced required drive torque. It ensures that the rear wheel can rotate freely even in harsh operating conditions and without any maintenance.
