ASTM D4172 ADDITION Auto Lubricant Anti Wear Performance Tester ASTM D2596 Four Ball Wear Test Machine

Auto Lubricant Anti-Wear Performance Tester

(Four-Ball Wear Test Machine) 　

Product model: JF3142

Product Introduction

This machine adopts four ф 12.7mm standard steel balls, in the form of sliding friction, under the condition of point contact pressure, evaluate the bearing capacity and anti-wear performance of lubricant (including oil film strength PB, sintering load PD, comprehensive wear value ZMZ, long-term wear D and other indicators). It can also determine the influence of temperature on lubricant lubrication performance.
