TBM Bearing Solutions by Application

Heavy-duty bearings designed for critical components of tunnel boring machines.

TBM Main Drive Bearings

The main drive bearing is one of the most critical components of a tunnel boring machine. It supports the cutter head rotation under extremely high radial loads, axial thrust loads and vibration conditions.

Recommended bearing types:

Cutter Head Bearings

Cutter head systems operate under heavy impact loads and continuous vibration. Reliable bearings help improve machine availability and reduce maintenance frequency.

Recommended bearing types:
  • Large Spherical Roller Bearings – Shock load resistance
  • Four-row Cylindrical Roller Bearings – Heavy radial loading
  • Customized bearing designs

TBM Gearbox Bearings

Drive systems require bearings with high precision, stable operation and long service life under continuous working conditions.

Recommended bearing types:
  • Cylindrical Roller Bearings – High radial capacity
  • Tapered Roller Bearings – Combined load applications
  • Spherical Roller Bearings – Misalignment compensation

Screw Conveyor Bearings

The screw conveyor system works in dusty underground environments. Bearings must provide reliable performance against contamination and continuous operation.

Recommended bearing types:
  • Spherical Roller Bearings
  • Mounted Bearing Solutions
  • Custom Sealing Designs
