The SKF radial spherical plain bearing with 20 mm bore diameter has 140 kN basic static load rating and 83 kN basic dynamic load rating. It has an inner ring with a sphered convex outside diameter and an outer ring with a correspondingly sphered but concave inside surface. This design make it particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated, or where oscillating or recurrent tilting or slewing movements must be possible at relatively slow sliding speeds, often accompanied with heavy loads.
