Block-on-Ring Test Machine
The Block-on-Ring Test Machine is a tribological testing system designed to evaluate friction and wear performance under stable line-contact conditions. Using a Block-on-Ring contact configuration, the system maintains constant linear contact and steady rotational speed, allowing you to reliably simulate real industrial contact conditions.
The machine supports dry and lubricated friction testing for lubricants, coatings, polymers, ceramics, and composite materials. A pneumatic loading system and programmable control enable stepwise or ramped control of load, speed, temperature, and motion mode, ensuring repeatable and standardized wear testing.
