shield tunnel machine

  Providing tunnel boring machine manufacturers with rugged, precision slewing ring bearings is a challenge nearly as big as the bearings themselves. Our experienced engineers specialize in custom designs for hard-rock or soft-rock machines, from main cutterheads and segment erectors to screw conveyors. All designs combine performance and technical efficiency with cost-effectiveness, and are proven with static and dynamic evaluation.
  We commitment to excellence continues through the manufacturing process, with precision machining in our ISO 9001:2000-certified facilities. Races are made from seamless rolled ring,
  bearing-quality steel, and gears can be cut into the inner or outer race and hardened to resist wear. Special sealing and lubrication arrangements are available to further enhance bearing life. We even design the metallic cage separators for the rolling elements to suit this  application.
