Lubricant Anti-Wear Performance Tester (Four-Ball Wear Test Machine)  
Product model: JF3142

Product Introduction
This machine uses four Ф12.7mm standard steel balls to evaluate the load-bearing capacity and anti-wear performance of lubricants (including oil film strength PB, sintering load PD, comprehensive wear value ZMZ, Long-term wear D and other indicators). The influence of temperature on the lubricating performance of lubricants can also be measured.
