roller mill is operated with the rolls out of tram or out of parallel, significant thrust loads may be exerted on the rolls and bearings. In machines with straight bore bearings, the forces may be enough to cause the rolls to shift sideways in the machine, even contacting the mill frame.
mill rotors are mounted on spherical roller bearings. This self-aligning bearing type can compensate for mis-alignments of the two plummer block housings, and possible rotor deflections. Two spherical roller bearings FAG 23228EASK.M.C3 are mounted, one acting as the locating bearing, the other one as floating bearing.
