Product Description

Lever four ball friction tester

The lever four ball friction tester is mainly used to evaluate the bearing capacity of lubricants in the form of sliding friction under extremely high point contact pressure. It includes the maximum non seizure load PB, sintering load PD, and comprehensive wear value ZMZ. In practical application, different evaluation indexes can be selected according to different uses of lubricants. The maximum ambient temperature of the test oil box can reach 250 ºC, and the time preselection, friction force, temperature and other presetting can be carried out. The friction coefficient of the friction couple can also be measured. The tester is mainly applicable to the evaluation of lubricating oil. It has broad application prospects in various professional fields of tribology, petroleum, chemical, energy and other industries, colleges, universities, research institutes (institutes) and other departments.
