Rotational Module

Rotational Wear Friction Test reproduces the rotational motion found in many real-world tribology mechanisms.

How does it work?

A pin or ball tip is loaded onto a test sample with precise weight and at a specific position from the center of rotation.

As the sample starts rotating, the tip creates a rotational wear track.

An arc test (back and forth) can also be performed at a specific degree
