B92 bearings with or without flange are intended for radial and axial movements. The bearings are wrapped of a cold formable homogenous bronze, which because of this will obtain exceptional material properties. The execution of the flange permits that the bearing also can carry axial loads. The standard sizes are fitted with holes, which are dispersed in a special way over the whole bearing – surface. These holes serve as lubricant reservoirs i.a. to rapidly build up a lubrication film in the moment of start and therewith reduce the start friction. These holes even lengthen significantly the lubrication intervals. The properties of the B92 material, together with the procedure of wrapping and calibration, make this type of bearing especially suitable for constructions, where high loads and relatively slow movements are occurring.
