Bearing Type Bearing Description Size          Range Capacity Range Gearing Options Typical Applications
4-point contact ball bearing - Good for multi-directional loading with high thrust and moment load capability.  Good for applications where the structures are less rigid. 20" inside diameter to 140" inside diameter Thrust to 7,000,000 lb      Moment to 16,000,000 ft-lb    Radial to 1,500,000 lb Internal to 96" inside diameter          external to 150" outside diameter           No gear Turntables
Radar
Pedestal cranes
Mobile cranes
Excavators
Wind turbines
Cross roller bearing - Bi-angular nature allows for multi-directional load capability.  Excellent stiffness capability due to line contact.  Good for applications requiring a high stiffness mount with exacting torque requirements. 20" inside diameter to 140" outside diameter Thrust to 5,000,000 lb      Moment to 12,000,000 ft-lb      Radial to 2,000,000 lb Internal to 96" inside diameter          external to 150" outside diameter           No gear Radar
