DIN 51350-6 Shear Stability Of Lubricating Oils Containing Polymers
This is KRL friction pair on a four-ball friction tester, uses SKF SKF 32008 tapered roller bearings to determine the shear stability of polymer-containing lubricants, including pressure fluids. The test results can be used to predict the permanent viscosity loss. The tap speed is 1500 rpm, the test force is 5000 Newtons, the temperature is 60 °C, the total number of revolutions is 1.74 million, the time is about 20 hours.

Four Ball Wear Tester
This test method, used for specification purposes, differentiates between lubricating fluids having low, medium, and high level of extreme-pressure properties. The user of this method should determine to his own satisfaction whether results of this test procedure correlate with field performance or other bench test machines.
