Say goodbye to leaf springs

Our company, which has adopted innovation as a principle, revolutionized the friction ring and named it the “STHILL Roller Bearing Ring”. Our goal was to design a new friction ring with low maintenance, high performance, minimum spare parts consumption and longer product life. Thanks to the new spring design where we have removed the leaf springs and thereby diminished the dust accumulation, we have reduced maintenance times and extended maintenace periods.

Friction rings are outdated. Now there is the Roller Bearing STHILL Ring which needs 90% less maintenance.

Roller Bearing STHILL Ring Advantages

  • Increased lifetime
  • Simple assembly/disassembly
  • Minimum spare parts consumption
  • No leaf springs collecting dust
  • Well suited for all core materials
  • Extended maximum clamping range
  • 90% reduced maintenance times and extended maintenance periods
  • The clamped winding cores do not slide to the side, thus producing rolls with smooth faces
  • Due to the reduced internal friction suitable for applications with very low tension, too
