Abstract
Bearing assemblies for supporting cylindrical, metal-rolling rolls. The bearings are housed in chock blocks and comprise both radial and thrust bearings. The radial bearings are hemi-cylindrical in shape and extend around approximately one half of the circumference of each roll and make contact with the surface of each roll thereby minimizing lateral roll deflections. A thrust bearing engages a fraction of the surface of at least one end face of each roll. Both the radial and thrust bearings are preferably made of high strength, mechanical graphite or carbon.
