Radial ball joint
SKF Radial spherical plain bearings comprise inner and outer rings sliding contact surfaces and are lubricated via the inner and outer ring. They can support radial forces, transmit motion and loads with low moment levels and thus keep bending stresses away from the adjacent structure. The bearings are particularly suitable for alternating loads with impact and shock type stresses and support low axial loads in both directions. Sealed spherical plain bearings are protected against contamination and water spray by lip seals. The radial spherical plain bearings requiring maintenance (steel-on-steel) have hardened sliding contact surface on both rings. They have both wear and corrosion resistant characteristics. Bearings with this sliding contact surface combination require regular relubrication. The high strength of the sliding contact surfaces make these bearings especially suitable for bearing arrangements where heavy loads of alternating direction, shock loads or heavy static loads have to be accommodated.
