Spherical plain bearings (SPBs), or bushings, are metal-on-metal bearings consisting of a spherically ground inner ring housed in a mating outer ring without any rolling elements. While all plain bearings are precision ground and made from through-hardened steel, custom orders are available and can include special materials, clearances, surface finishes or configurations to accommodate unique applications. Our SBT and SBDT designs feature lubricating holes and grooves in the outer ring for easy relubrication through the housing.

Available in inch and metric sizes from 12.7 mm to 600 mm (.5 in. to 23.622 in.) bore

This series of plain bearings is similar to the SF and FS types, but also includes lip seals that are retained in the outer ring and withstand high grease pressures during lubrication. These lip seals assure full distribution of the lubricant to all bearing surfaces and protect against internal contamination. While all of our plain bearings are precision ground and made from through-hardened steel, custom orders are available and can include special materials, clearances, surface finishes or configurations to accommodate unique applications.
