Accurately Assess Lubricant Anti-Wear Performance – Empowering Quality Upgrades
In the field of lubricant development and quality control, anti-wear performance is a key indicator of product excellence. The DFYF-907 Lubricating Oil & Grease Anti-Wear Tester (Four-Ball Method) strictly complies with multiple national and international standards. Based on the classic four-ball friction pair principle, it provides reliable and repeatable test data for the load-carrying capacity, anti-wear performance, and temperature characteristics of lubricants.
Core Advantages
✔ Multi-standard, Multi-function
Complies with GB/T 3142, SH/T 0189, SH/T 0202, SH/T 0204 and similar standards. Measures maximum non-seizure load (PB), welding load (PD), combined wear value (ZMZ), and long-term wear data of lubricating oils, as well as anti-wear performance of greases.
✔ Wide Adjustable Speed Range – Simulates Real Operating Conditions
Spindle speed continuously adjustable from 1000 to 2800 r/min with an accuracy of ±40 r/min, meeting friction and wear test requirements under various speeds.
✔ Lever-type Manual Loading – Accurate and Reliable Force Application
Lever-type loading system with axial test force range of 60N to 8kN, force accuracy ±1%. Intuitive operation and excellent repeatability.
✔ Intelligent Temperature Control – Study Temperature Effects
Temperature adjustable from ambient to 200°C using a rod-type heater. Enables evaluation of temperature influence on lubricant performance, providing data support for high-temperature applications.
✔ Easy Wear Scar Measurement – Clear Results
Equipped with a dedicated high-precision microscope for rapid reading of wear scar diameter on steel balls, reducing human error and improving test efficiency.
✔ Flexible Timing Settings – Adapts to Various Test Cycles
Timer range from 1 second to 99 hours 99 minutes, suitable for everything from short-term extreme pressure tests to long-term wear procedures.
