No lubrication ever again – thanks to the maintenance-free disc bearings

With no need to lubricate the disc bearings, this results in a significantly reduced overall maintenance time. Face seals have been used for decades in road construction equipment where rollers on the running gear of caterpillar-tracked vehicles have to be effectively sealed and work with complete reliability under the toughest of operational conditions.

  • Maintenance-free disc bearings with face seals and life-long lubrication
  • Maintenance-free overload protection via rubber spring elements
  • Individual disc suspension for optimised contour following and excellent through passage
