ABSTRACT:
A bearing assembly for a cylinder in a printing press including an anti-friction bushing interposed between the spindle of the cylinder and a bore in the press frame. In contact with the outside surface of the bushing is a cylindrical layer of durable anti-friction plastic material formed of a flat ribbon which is of uniform thickness dimensioned to fit snugly to prevent any radial play between the bushing and the frame. In the preferred form of the invention two bushings are used, one inside the other, with the layer of plastic material interposed between them. At least one of the bushings may have inner and outer cylindrical surfaces which are eccentric with respect to one another and may be provided with means for rocking adjustment to provide limited throw of the spindle. The preferred form of plastic material is polytetrafluoroethylene, commonly known as Teflon.
