B90 – bearings with or without flange are intended for radial and axial movements. The bearings are manufactured 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 diamond shaped lubrication indents on the bearing surface. These indents serve as lubricant reservoirs i.a. to rapidly build up a lubrication film in the movement of start and therewith reduce the start friction. The properties of the B90 material, together with the procedure of wrapping and calibration, make this type of bearing expecially suitable for constructions, where medium or high loads and relatively slow movements are occurring.
