The Multi-Purpose Friction and Wear Tester is a laboratory testing system designed to evaluate friction behavior and wear performance of engineering materials under controlled contact, load, speed, and temperature conditions. You can use this instrument to conduct standardized and comparative tribological testing by simulating rolling, sliding, and mixed lubrication conditions commonly encountered in industrial applications.
