Plastic slewing ring ball bearings
maintenance-free and tough

iglidur® PRT slewing ring bearings are ready-to-install bearings for lubrication-free dry operation. The design is not based on re-circulating components, 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.

Advantages of the iglidur® PRT slewing ring bearings

Cost-effective

Cost-effective

Manufacturing with injection moulding or 3D printing guarantees cost efficiency and creates the geometrical freedom to optimise use of installation space. Thanks to the flexible modular system, the slewing ring ball bearings can be extended as required. 

Lubrication and maintenance-free

Lubrication-free The iglidur® PRT slewing ring is designed as a ready-to-install solution, so it is ready to use straight away and requires no additional lubrication or maintenance. This saves time and reduces maintenance costs.

Up to 60% lighter

quiet

The iglidur® bearing technology impresses with ultra-light materials, such as plastic and aluminium. This enables you to achieve greater efficiency in your application. 

Quiet dry operation

Quiet operation for slewing ring bearing PRT
The igus® PRT slewing ring bearings with plastic sliding elements produce significantly less noise and vibrations. For you as an operator, plastic gears - for example in robots - lead to an application that is up to four times quieter.

Resistant to chemicals and media

Temperature
Suitable for the food industry (FDA) and for daily cleaning with cleaning agents and high pressure. PRT slewing ring bearings are also an ideal solution for special applications with high temperatures of up to 180°C or ESD.
The rings are made of plastic, aluminium or stainless steel.
 

Tested and proven
