Features
A rod end bearing is a mechanical articulating joint. Such joints are used on the ends of control rods, steering links, tie rods or anywhere a precision articulating joint is required. A ball swivel with an opening through which a bolt or other attaching hardware may pass is pressed into a circular casing with a threaded shaft attached. The threaded portion may be either male or female. Rod ends has spherical plain bearing inserted.
Designation
Rod ends with built-in plain bearings are ready to mount parts and can be quickly and easily fixed to the interacting machine elements. The wide variety of engineering solutions are based on the one hand on implementing various plain bearings (various materials of friction parts) and on the other hand on various assembly options (internal or external threads, right or left hand threads) enable lots of construction solutions. Standard make (TK) bases on the friction pair steel/PTFE . For heavy duty operation SS/M rod ends are most suitable, where special acid resistant steel and brass constitute the friction part.
