Computer Controlled Vertical Universal Friction And Wear Testing Machine

Brief introduction:

Computer controlled vertical universal friction and wear testing machine is a Multi-specimen friction and wear testing machine. it is designed for simulating, evaluating and testing almost all kinds of oil (high-class serial hydraulic oil, lubricant, combustion oil and gear oil) and metal, plastic, coating rubber, ceramicetc.)

It is widely used in the Tribology field, petrol chemical industry, mechanical, energy resource, metallurgy, space flight, engineering areas, college and institute etc.
