iglidur® PRT - polymer slewing ring bearing

Polymer slewing ring bearing

iglidur® PRT is a slewing ring bearing with the proven advantages of the igus® polymer bearings. The sliding elements made of iglidur® J operate absolutely maintenance and lubrication free. The mating rings of the slewing bearing are made of aluminium or stainless steel; the mating surfaces of iglidur® J sliding elements are hard-anodised. All fastening screws are made of stainless steel.

Typical sectors of industry and
application areas

Slewing ring bearings for material handling

Slewing ring bearings for automation technology

Slewing ring bearings for assembly technology

Slewing ring bearings for stagecraft and lighting technology

Slewing ring bearings for energy generation and much more.


When to use polymer slewing ring bearing?

  • When a ready-to-install solution is sought
  • As rugged, corrosion-resistant bearing unit for high loads
  • For extreme overturning torques
  • For application in alternating ambient media
  • For maintenance-free and lubrication-free applications
  • For low to medium surface speeds

When not to use ?

  • For fast, continuous rotations
  • at temperatures up to 180° C
  • When only low driving forces are available at high loads
  • For extreme requirements in roundness and precision
