Cylindrical bearing, intended for radial and axial movements.
WB702-bearings with or without flange are intended for radial and axial movements. The bearings are manufactured of a cold formable homoge-nous bronze, which because of this will obtain exceptional material pro-perties. 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. The properties of the WB702-material, together with the procedure of wrapping and calibration, make this type of bearing especially suitable for constructions, where medium or high loads and relatively slow movements are occurring.
