Ball Joint Rod Ends

LS Ball Joint Rod Ends, technical data, rules and guidelines, fitting and lubrication information

Ball joint rod ends have a ball joint housing with a sphered convex inside surface and a ball joint shank with a correspondingly sphered but concave outside surface. Ball joint housing is with left or right-hand thread. There are two kinds of sliding contact surfaces: steel to steel and steel to zinc base alloy.

Ball joint housing is made of zinc base alloy or carbon steel, ball joint shank is made of a steel ball and a stud which is joined by precision welding, it has characteristics of self-aligning, wear-resistance and easy mounting.
