ASTM D4170 ASTM D2783 Fully Automatic Lubricating Greases Fretting Wear Protection Tester

• Model NO.: TP-10A
• HS Code: 9027

Product Description

TP-10A Four Ball Friction Tester adopts the latest guidance and control technology, mainly in the form of sliding friction, to evaluate the bearing capacity of lubricant under extremely high point contact pressure. It includes three indexes: the maximum non seizing load Pb, the sintering load Pd and the comprehensive wear value ZMZ. The four ball friction tester can also be used for long-term anti-wear test of lubricant, measuring friction coefficient and recording friction and temperature curves. The four ball friction tester can be equipped with a high-precision measuring device, which can realize the calculation screen display, measurement and recording of friction pairs. With special accessories, the simulation test of end friction and material can also be carried out.
