Cenius face seal

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.

The benefits:

• Optimum levelling by means of spring steel tine levellers or levelling discs
• The height and angle of the outside discs can be adjusted separately for a perfect profile when matching bout to bout  
• Maintenance-free disc bearings with face seals and life-long lubrication
• Maintenance-free stone protection via sprung rubber buffers as standard
