Rod ends consist of an eye-shaped head with integral shank forming a housing and a standard spherical plain bearing, or a spherical plain bearing inner ring, or a spherical plain bearing inner ring and a sliding layer between the bore of the head and the inner ring. As a rule, rod ends are available with left or right-hand female or male threads. Rod ends from AST have the sliding contact surface combinations steel-on-steel, steel-on-bronze, steel-on-PTFE composite material, and steel-on-PTFE fabric.
