Bearings for Tunnel Boring Machines (TBM)

Tunnel Boring Machines operate under extreme loads, continuous vibration, abrasive dust and high-pressure environments. These machines require exceptionally durable bearings designed to withstand long operational cycles without failure. We supply a full range of bearings for TBM applications, suitable for cutter heads, main drives, gearboxes, hydraulic units and support systems. Worldwide delivery is available.

Main Types of Bearings Used in Tunnel Boring Machines

• Spherical Roller Bearings – Designed for heavy radial loads, impact forces and misalignment.
• Tapered Roller Bearings – Suitable for combined axial and radial loads in cutter head drives.
• Cylindrical Roller Bearings – High radial load capacity for main drive assemblies.
• Thrust Bearings – Handle extreme axial forces during boring operations.
• Needle Roller Bearings – Compact solutions for hydraulic and auxiliary systems.
• Sealed Bearings – Protection against slurry, moisture, dust and contaminants.

Typical TBM Applications

• Cutter head rotation units
• Main drive systems
• Gearboxes and reduction units
• Hydraulic pumps and motors
• Screw conveyors and slurry pumps
• Guidance, support and backup systems

Key Advantages of Our Bearings for TBM Operations
