Description Our exceedingly robust Walkersele® TBMS radial lip seals are designed to protect the cutting head bearings of tunnel boring machines.
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.
