Radial Spherical Plain Bearings Highly versatile, radial SPBs are known for their easy maintenance and being an economical option. Call to speak with a spherical plain bearing expert. Tie rods for steerable axles come in a variety of finishes and styles.Spherical Plain Bearings Radial spherical plain bearings consist of an outer ring and an inner ring. This design makes them particularly suitable for bearing arrangements where oscillating movements are required and can accommodate misalignment.
Spherical Plain Bearings - Overview. Download PDF of this information. Radial spherical plain bearings have an inner ring with a sphered convex outside surface and an outer ring with a correspondingly sphered but concave inside surface. Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated.The introduction of ISB spherical plain bearings, both those requiring maintenance and those that don’t, allows the transmission of motion and loads in the absence of cups, therefore in the absence of radial loads and flexion tension in the structural elements.
