Spherical plain bearings requiring maintenance
The Spherical plain bearings requiring maintenance are sliding bearings composed of an inner ring with cylindrical bore and the outer ring with concave surface. The contact surfaces are made of steel/steel or steel/bronze and must be lubricated through the existing annular grooves. They can also be delivered with sealing lips being lubricated for life by the manufacturer. Depending on the construction variant, they can take over radial, axial or combined loads simultaneously with pivoting, tilting and rotating movements.
