Description

Measure the bearing capacity of various lubricants (lubricating oil, grease and solid lubricant film): Under the specified test conditions, compare the maximum test force that the lubricant can withstand before the oil film breaks

Measure the abrasion resistance of various metal and non-metal materials under sliding friction conditions: evaluate the resistance of materials through the change of test piece weight and size before and after the test, the change of the width of the wear scar on the test block, and the change of friction during the test grinding performance.

Calculate the friction coefficient of the material by measuring the friction force: the machine can directly measure the friction between the ring blocks through the lever system, and can calculate different working conditions under the condition of changing the test parameters (load, linear speed, lubrication conditions) coefficient of friction.
