Slewing rings add life to Owl Installation

PRT Slewing Ring Bearing Application

Application Overview

  • What was needed: PRT slewing ring
  • Requirements: The turntables should be wide enough to allow mechanical cables, components and lighting elements to pass through. They had to withstand high axial and dynamic loads and be maintenance-free despite the weather.
  • Success for the customer: The PRT slewing ring bearings from igus® are resistant to chemicals, vibration damping and have low moisture absorption. They are also very robust and can withstand high load trade show.

"The axial and dynamic load range is actually oversized for the weight of the owl's head, but gives us security in case visitors climb on the owl or pull on its head."
