This Sealmaster TR Series three-piece spherical rod end bearing has a Y-stud and is used in motion transfer linkage assemblies. The housing is made of machined carbon steel that is plated for corrosion resistance. The bearing has a female shank with right hand threads for connecting to rods, and the shank has wide wrench flats for tightening. The bearingâs race is made of plated carbon steel and the alloy steel ball is heat treated and chrome plated for resistance to wear and corrosion. A carbon steel Y-stud with right hand threads is mounted in the bore of the ball to provide right angle connections. The Y-stud can accommodate up to 25 degrees of angular misalignment in any direction for flexibility in linkage design, and it is plated for resistance to corrosion. This bearing is lubricated with grease at the factory and requires no additional lubricants. It has a maximum operating temperature of 350 degrees F (177 degrees C). This spherical rod end bearing is suitable for use in various applications such as textile manufacturing equipment, agricultural machinery, and off-road vehicles, among others.
Rod end bearings, also called heim joints or spherical rod ends, are articulating joints that are attached to the ends of tie rods, steering links, and cylinders to provide a transfer of motion and force between two points. They consist of a spherical swivel with a cylindrical bore through which a bolt may pass pressed into a housing that has a threaded shank. Rod end bearings are used in applications such as steering linkages, agricultural machinery, and textile manufacturing equipment, among others
