The Variable Load Friction and Wear Test System is designed to simulate real operating conditions by applying controlled friction motion under variable vertical loads. Driven by a servo motor with a gear-and-rack mechanism, the system enables simultaneous measurement of friction force and wear volume, supports three-dimensional wear pattern analysis, and accurately identifies critical load points associated with wear transitions. It offers flexible test modes, high operational safety, and compliance with multiple international testing standards.
