Many applications require spherical bearings that can be oscillated reciprocally and can withstand misalignment. Rolling bearings can only partially meet these requirements because they are usually designed for continuous rotation and can only tolerate limited centering errors. Therefore, SKF manufactures spherical plain bearings, rod ends, and bushings that provide an economical solution to these challenges. Spherical plain bearings, rod end bearings and bushings are available in a variety of designs and have different combinations of sliding contact surfaces. Each design and combination has unique properties that make it suitable for certain specific applications.
