Four Ball Wear Test ASTM D4172
Four Ball Wear Test Description
The Autoload Seta-Shell Four Ball Lubricant Tester determines the friction properties of extremely high-pressure oils and greases. Designed to perform the Four Ball Wear Test ASTM D4172,Ā A ball, mounted in a chuck, is rotated against three stationary balls in a pot containing the sample lubricant. The digital speed controller hasĀ 1200, 1475 and 1760 rpm. A load, adjustable in the range of 6 to 800 kgF, is applied to the balls via a balance beam and electric jack. The applied load is displayed on a digital readout. The torque transferred between the rotating and stationary balls is measured and displayed. The digital timer, with a range of 0.1 seconds to 9999 hours, can be used to control the duration of the test.
