Plastic PRT slewing rings
maintenance-free and robust

iglidur PRT slewing rings 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 in combination with high temperatures, moisture, chemical contact or in the food industry.

Application examples - slewing rings in real life

Flip chart with PRT slewing ring bearing

Rotating digital flip chart

The compact design of the PRT-02-30 makes it the ideal flip chart solution. Thanks to ready-to-install delivery, it also did justice to easy assembly. In addition, due to the plastic sliding elements made of iglidur material, maintenance work is no longer necessary after installation.

More on the application

Personal robot

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.

Coffee robot with PRT slewing ring bearing

Coffee robot

The manufacturer of the coffee robot was looking for a maintenance-free slewing ring with low starting torque. PRT-04 slewing ring bearings from igus are now used in the dispensing system as they easily meet all requirements.

More on the application

Owl sculpture with PRT slewing ring bearing

igus slewing rings in art installation with three-metre owls

The PRT slewing rings can withstand a static axial load of 27,000 newtons and a dynamic axial load of 7,000 newtons. Thanks to the large PRT outer diameter of 450 millimetres, the sculpture requires less supporting material. The large inner diameter of 430 millimetres also makes it easy to install fibre-optic cables to illuminate the installation.

Application examples
