- Scope
- This method is suitable for evaluating the bearing capacity of lubricants on a four-ball extreme pressure testing machine, including the maximum non-seizing load PB, sintering load PD, and comprehensive wear value ZMZ three indicators. In practical applications, different evaluation indicators can be selected according to various uses of lubricants. Note: ①The maximum non-jamming load is commonly known as PK point (representing oil film strength). ②Comprehensive wear value ZMZ is also called comprehensive wear index, average Hertz load, and load wear index.
