Variable Load Friction and Wear Test System
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.
