Linear Constant-Speed Reciprocating Friction and Wear Tester
The Linear Constant-Speed Reciprocating Friction and Wear Tester is a specialized instrument for evaluating friction and wear performance of materials and surface coatings under linear constant-speed sliding conditions. The instrument can accurately measure friction coefficient, wear depth, wear width, and wear volume under various loads, sliding speeds, stroke lengths, and temperature conditions, in dry or lubricated environments. The testing process is computer-controlled with real-time data acquisition and graphical display, suitable for material research, process evaluation, and quality control.

Test Principle
During testing, the drive system moves the specimen in a linear constant-speed reciprocating motion under a set load, creating a stable and controlled friction interface. Friction sensors collect real-time friction force signals and calculate the friction coefficient. The wear measurement system accurately records wear depth and width to determine wear volume. By comparing friction and wear parameters under different materials or test conditions, the tester provides quantitative evaluation of material wear resistance.
