Vacuum Ball - Disk Friction Tester

A vacuum ball-on-disk friction tester is a device used to simulate friction and wear behavior under actual operating conditions, in order to evaluate the performance of materials, lubricants, or other wear-resistant materials.

Application

The vacuum ball - disk friction tester is a device specifically used for evaluating the sliding friction coefficient of point contact and the wear life of materials under vacuum and different atmospheric environment conditions. Its main purposes include:

Material Friction Performance Evaluation

- Simulate the actual friction conditions of materials in a vacuum or specific atmospheric environment, test the friction coefficient of materials, and evaluate their friction performance. - Test the friction behavior of materials under different loads and speeds to obtain friction performance data, providing a basis for material research, development, and optimization.
