The friction and wear characteristics of extreme pressure oils and greases are determined by the Seta-Shell Four Ball Lubricant Tester (manual load). Used in tribology research facilities and in the regular inspection of finished lubrication products for quality.

Three of the four programmable presets on the digital speed controller are already set to the most frequently used speeds. The digital timer, which has four ranges and can measure time from 0.1 seconds to 9999 hours, can control how long the test will last. A torque sensing system automatically cuts off the power to the drive motor during a test if the balls weld.
