Self-lubricating PRT slewing ring systems for every application

iglide® PRT slewing ring bearings are ready-to-install rotary joints for self-lubricating, dry operation. The design is based on maintenance-free sliding elements made of tribologically optimized iglide® materials instead of metal rollers or balls. In combination with rings made of lightweight anodized aluminum or stainless steel, these iglide® materials are universally applicable. They can be used in applications with high temperatures, moisture, chemicals and even for food processing.


  • 100% maintenance-free and self-lubricating
  • Corrosion-resistant and hygienic
  • Wear-resistant
  • Resistant to dirt, dust and humidity
  • Very slim design
  • Robust
  • Cost-effective
  • Ready-to-install & easy to assemble
