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
applications:

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.

PRT Expert selects the best solution

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

PRT Expert selects the best solution

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
