iglidur® PRT slewing ring bearings – configure and order online

iglidur® PRT slewing ring bearings are ready-to-install rotary joints for lubrication-free, dry operation. The design is not based on metallic rollers or balls, but on maintenance-free sliding elements made of the proven tribologically optimised iglidur® materials in combination with rings made of lightweight anodised aluminium or stainless steel. These iglidur® materials are universally applicable. They can be used in applications with high temperatures, moisture or chemical contact or even in the food industry.

Selected application examples

Transport system

The igus® slewing ring bearings are more cost-effective than the previous self-built solution. Moreover, the entire system is suitable for use in clean rooms.

Machine tool manufacturing

Lubrication-free and maintenance-free slewing ring bearings move the control panel. They ensure low coefficients of friction for a low actuation force during pivoting.

Core joining device

With this application for the casting of cylinder heads, lubrication-free bearings are of the utmost importance as quartz sand is used. The solution: iglidur® PRT slewing ring bearing.

Moving Head

Moving-head spotlights are often characterised by heavy, metal ball bearing designs. Lightweight and low-maintenance slewing ring bearings from igus® are used in this application.

Assembly station

This assembly station is characterised by continually turning in a circle. Circular movements are always accompanied by great frictional resistance, which means the conventional bearings quickly reach their limits. The solution: maintenance-free and lubrication-free slewing ring bearing from igus®.

Further slewing ring bearing application examples

In a great variety of industries, polymer slewing ring bearings are used to technically refine solutions and save costs.
