FINE can design and manufacture the tunnel boring machine main bearing.Normally, the range of slewing bearings used on tunnel boring machines is between 2.5 and 6 meters in outer diameter, such bearings operate in harsh conditions–dirty, corrosive environments with heavy loads and short life expectancy.
FINE can provide tunnel boring machine slewing ring bearings-engineered to their demanding specifications and delivered on time-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 cutter heads and segment erectors to screw conveyors. All designs combine performance and technical efficiency with cost-effectiveness, and are proven with static and dynamic evaluation.
