Rotek Series 4000 slewing bearings are built with greater internal clearance than the Series 3000 models. Advantages include lower frictional torque and the ability to function in mounting structures with less accuracy and rigidity than required for other style of slewing bearings.
Raceway Diameters: Standard models from 12" to 180"
Thrust: from 100,000 to 4,200,000 pounds
Moment: from 123,000 to 12,000,000 foot-pounds
Radial: from 10,000 to 420,000 pounds
Gearing: Internally geared, externally geared or gearless models are available
