SH120 automatic four ball machine grease wear resistance tester is
in the form of sliding friction, under the condition of extremely
high point contact pressure, mainly used to evaluate the bearing
capacity of lubricants.
In practical application, different evaluation indexes can be
selected according to different uses of lubricants.

The four-ball friction testing machine can also do lubricant
long-term wear resistance test, determination of friction
coefficient, record friction and temperature curves.
The use of special accessories, can also carry out the end face
friction and material simulation test.
