Rotary Reciprocating Friction and Wear Tester

The Rotary-Reciprocating Friction and Wear Tester is a precision scientific instrument designed to evaluate the tribological performance of materials, surface coatings, and components. This device simulates various motion types including rotational, linear reciprocating, and ring-block motion, under controlled conditions such as load, speed, frequency, stroke, duration, counterface material, surface roughness, and hardness. It provides comprehensive assessments of material or coating performance by measuring key parameters like test force, friction force, and temperature. The system dynamically generates real-time curves for these parameters. Automatic shutdown and alarm protection are in place to ensure safety if preset limits are exceeded.

Application

This tester is designed for use in material selection research, surface coating evaluation, tribological studies, reliability testing, and industrial product quality inspection. It is ideal for laboratories, research institutes, and industrial testing environments that require accurate friction and wear analysis under carefully controlled mechanical and environmental conditions. Typical applications include:

Material performance evaluation (metals, polymers, composites)
