The Table Top Automated Four Ball Tester with integrated servo-pneumatic loading system is new generation test rig, designed & developed by M/s. Magnum Engineers as per ASTM & IP standards to conduct test for determine the Co-efficient of Friction of Lubricants, wear preventive (WP) & extreme pressure (EP) properties of lubricant characteristics of lubricating oils under variety test conditions. This test equipment can also be used to determine load- carrying properties of lubricants by load wear index and weld point method.

Test load is directly controlled through a software based close loop servo pneumatic drive, which enables and precise control over load application. The pneumatic loading method allows the user to have a better control over the test load and application method.
