Automatic Four Ball Wear Tester
Automatic Four Ball Wear Tester TT-2783Z
Automatic Four Ball Wear Tester TT-2783Z is used to evaluate the Wear Preventive (WP) and Extreme Pressure (EP) characteristics of greases and lubricating oils in sliding steel-on-steel applications.
It adheres to the ASTM D2783, ASTM D2266, and ASTM D4172 Standard Test Methods for Wear Preventive Characteristics of Lubricating Fluid (Four-Ball Method). This tester uses sliding friction under high point contact pressure to assess the carrying capacity of lubricants. It measures three key indices: maximum no-seizure load (PB), sintering load (PD), and composite wear value (ZMZ). Additionally, it is utilized for long-term abrasion resistance tests to measure the friction coefficient.
