Four Ball Tester Toron4BT™ 1000
Parent Product
Product Categories
Four Ball Tester Toron4BT™ 1000 evaluates the load-bearing capacity of lubricants under high-contact pressure in sliding friction conditions. It measures key performance indicators, including maximum non-seizure load (Pb), sintering load (Pd), and composite wear value (ZMZ). Additionally, it conducts long-term wear resistance tests and determines the coefficient of friction.
