They are well proven on many successful tunneling projects, including the Channel Tunnel (7.8m diameter) and the Airport Link Railway, Sydney (11m diameter). 

Special features

  • Exceedingly robust design of radial lip seal that must work efficiently for the life of a tunnel boring project.
  • Manufactured from extremely tough, abrasion resistant elastomer-proofed fabric, and fitted with an 'O' ring to energise the lip.
  • Banks of Walkersele® TBMS seals are installed behind the cutting head to protect the bearings from water, slurries, highly abrasive dust and grit.
  • Also suitable for screw-conveyor and other slow rotary abrasive duties.

Walkersele TBMS availability
We hold a number of tools for Walkersele® TBMS designs. However, as each tunnel boring machine is custom-built for a specific tunnelling project, we recommend that you contact our Technical Services Team at concept design stage to discuss sealing requirements in detail.
