Automatic Four Ball Tribometer - Friction and Wear Tester – Toron4B10A™
Parent Product
Product Categories
Automatic Four Ball Tribometer - Friction and Wear Tester (Toron4B10A™) is designed to assess the load-carrying performance of lubricants under extreme point-contact pressure during sliding friction. It provides three key measurements: maximum non-seizure load (PB), welding load (PD), and comprehensive wear value (ZMZ). In addition to these evaluations, the device can perform extended anti-wear testing and accurately measure the friction coefficient of lubricants.
Applicable standards
