WebFour Ball Tester (Desktop) - FBT3 A new generation, compact and automatic four ball tester that can test your lubricating oils, greases and additives for their Wear Preventive (WP) and Extreme Pressure (EP) properties. Complies with numerous ASTM, DIN and ISO standards. Learn More High Frequency Reciprocating Rig (HFRR) WebThe four-ball tester was used in this analysis to demonstrate the lubricity of tire pyrolysis oil (TPO). The tribological performance of the tire pyrolysis oil was compared with diesel fuel (DF) and their blends, DT10 (TPO 10%, Diesel 90%) and DT20 (TPO 20%, Diesel 80%). A scanning electron microscope (SEM) was used to investigate the wear scar.
