Welcome to RBC's on-line Engineering Data Guide for Spherical Plain Bearings. RBC has been a pioneer in spherical bearing technology since inventing the fractured outer race design over 40 years ago.
Since that time, RBC has continued to introduce industry leading innovations such as high misalignment, angular contact, extended inner ring, tapered bore, case carburized, and enhanced lubrication groove spherical bearing designs. These advanced products are used in pivoting, high load bearing applications where angular misalignment is required. Most typically, RBC spherical plain bearings are employed in hydraulic cylinder rod ends, vehicle steering linkage suspensions, heavy equipment articulated joints, and other severe duty uses.
