Block-On-Ring Module

Block-on-Ring Test is a widely used technique that evaluates the sliding wear behaviors of materials in many different simulated conditions.

How does it work?

A Block-On-Ring test allows a reliable ranking of material couples for
specific tribological applications.

A block is pressed down on a rotating ring.
