| K93100 Four Ball Tester The Four Ball Tester is used to test the Wear Preventive (WP) and Extreme Pressure (EP) characteristics of greases and lubricating oils in sliding steel-on-steel applications. The point contact interface is obtained by rotating a 12.7mm diameter steel ball under load against three stationary steel balls immersed in the lubricant. The normal load, frictional force, and temperature can be monitored using WinLube, the supplied Windows-based Data Acquisition Software. The rotating speed, normal load, and temperature can be adjusted in accordance with published ASTM and IP test standards. For evaluating the Wear Preventive characteristics of lubricants, the subsequent wear scar diameters on the balls can be measured using a graduated-scale microscope. The wear scar can also be captured using an optional Closed Circuit Digital (CCD) camera and measured using our Wear Scar Analysis Software. For evaluating the Extreme-Pressure (load-carrying) capacity of lubricants, the normal load at which welding occurs at the contact interface can be recorded.
