SQL rod ends are L-shaped, left-hand threaded, angular rod ends stems fitted with a dust seal (indicated by the suffix RS). They are made of steel over bronze, synthesized with PTFE for the sliding surfaces. Their inside diameter can vary from 5 to 22 mm. They require no lubrication and can withstand temperatures ranging from -50 to +130°C. They are commonly used in applications involving moving parts such as steering or axles, where self-alignment is required.
