Main Bearing Seal.
Isolates external mud and water from the bearing lubrication system, preventing the bearing from rusting and failing (e.g. Herrenknecht, Komatsu shield machine main seal).
Cutter Drive Seal: Protects the cutter drive motor and gearbox from rust and corrosion.
Protects the drive motor and gearbox from mud and sand intrusion caused by the rotating cutter disk.
Screw conveyor seals.
Maintains the pressure balance in the chamber during the discharge process, preventing soil leakage or groundwater influx.
Hydraulic Cylinder Seal.
Ensure that the propulsion system cylinders have no leakage under high pressure to maintain the accuracy of digging.
