BLOCK ON RING

Block on Ring Tester

A test block is loaded against a test ring that rotates at a given speed for a given number of revolutions. Block scar and ring scar volume is calculated after the test using the integrated profilometer . The friction force is continuously measured during the test with a load cell. These data, combined with normal force data, are converted to coefficient of friction values and reported.
