The Block-on-Ring Test Machine is a tribological testing system designed to evaluate friction and wear performance under stable line-contact conditions. Using aBlock-on-Ringcontact 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.
Application
You can use theBlock-on-Ring Test Machinefor the following applications and test specimens:
Friction and wear performance testing of lubricating oils and greases
Wear resistance evaluation of coatings under dry or lubricated conditions
Tribological analysis of polymers, ceramics, and composite materials
Friction and wear testing under high-temperature and low-temperature environments
Simulation of industrial material contact conditions with line contact geometry
Standardized performance evaluation of engineering materials
Research and development testing for automotive components
Quality control testing in mechanical, aerospace, and lubricant development laboratories
