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.
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.
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.

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.
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.
In a great variety of industries, polymer slewing ring are used to technically refine solutions and save costs.
Lightweight
Due to sliding elements made of plastic and even lighter with aluminium housing.
Quiet
No noises caused by metal friction or metal balls.
Robust
Polymer sliding elements are insensitive to dirt and moisture.
✅ Tailor slewing ring bearings to your application
✅ Various external and internal gearings
✅ Angle stop, snap mechanism and much more
✅Ready to install and easy to assemble
✅ 100% maintenance-free and lubrication-free
✅ Eight installation sizes
The new PRT-04 micro is our smallest PRT. Ideal for confined installation spaces.
With electronic closing control mechanism
For difficult to access and confined installation spaces.
For individual applications
The PRT-04 locking system enables precise adjustment of the slewing ring bearing, even under heavy load. The locking system can be released and adjusted quickly and easily by hand.
In addition, you benefit from an extensive and constantly growing modular system of the PRT-04 series.
Elegant and yet inconspicuous appearance. Ideal for use
as a visible part in furniture or in applications where reflection
should be avoided as far as possible.
The PRT Sliding Element Replacement KIT for the PRT-01 and PRT-04 series allows you to replace worn sliding elements with new ones. Extend the service life of your PRT slewing ring bearings and protect the environment. The replacement kits are available in four different materials, which allows them to be used in different applications.
We carry out tests so that you don't have to. Find out how our products are tested in the industry's largest test laboratory. In addition to standard tests, we also carry out individual customer tests.
Our facilities for testing applications and materials cover a total of 3,800m². Every business sector has its own laboratory to test products in realistic conditions.
Fabian Wieking, our Product Manager for PRT Slewing Ring Bearings, will address the subjects slewing rings and the extensive modular system of our PRT-4 series in this seminar.
