iglide® PRT - Polymer Slewing Rings

Polymer slewing ring bearing

iglide® PRT is a slewing ring bearing with the proven and tested advantages of the igus® polymer bearings. The sliding elements made of iglide® J operate absolutely free of maintenance and lubrication. The slewing ring housing parts are made of aluminum, and the counter-running surfaces of the iglide® J sliding elements are hard-anodized. All binding screws are made of stainless steel.

Typical industrial sectors and

Turntable bearing for materials handling

Slew bearings for automation systems

Slewing bearings for assembly technology

Turntable bearings used in stage and lighting technology

Large bearings for energy generation, etc.


When to use polymer slewing rings?

  • 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 self-lubricating and maintenance-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
