1. The four-ball tester can be used to determine the anti-wear performance of lubricating oil and evaluate the load-bearing capacity of lubricants, including constant wear, maximum non-seizure load(PB), welding load(PD), comprehensive wear value ZMZ, friction coefficient and friction curve, etc.
2. Determines the Wear Preventative (WP) and Extreme Pressure (EP) characteristics of lubricating oils and greases in sliding steel-on-steel applications. The test consists of rotating a steel ball under load against three stationary steel balls coated with lubricant. Measurements are taken at the rotating speeds, temperatures, and duration as specified by published standards. The load-wear index can be calculated from the weld point in EP tests, and lubricant comparisons can be made based upon scar diameters incurred from wear tests.

1. Brand 19-inch high-definition LCD display, mouse and keyboard control.
2. Embedded host system:
The embedded host system includes embedded industrial-grade motherboard, electronic hard disk, memory, USB cable, HDMI cable, external LCD display, external keyboard, and mouse. It has strong versatility and has network and USB external interfaces, which can be Carry out information inquiry, networking and data exchange.
3. The main body of the testing machine adopts bearing steel structure and precision machining. It has the characteristics of rigidity, shock resistance, high hardness and extremely high concentricity. The radial deviation of the steel ball on the upper part of the key component bowl, measured at a distance of 3.5mm from the lowest point of the steel ball, is 0.01mm, which is the latest scientific and accurate design. The operation is stable, the measurement data is accurate, and the repeatability is excellent.
4. Loading control mode: lever type; the loading force is constant and no fluctuation during the test.
5. The speed of the servo motor can be set and the speed can be displayed in real time.
6. The friction force detection is displayed on the LCD screen, and the high-precision thrust sensor is selected for real-time measurement, and the test results are more accurate.
7. The spindle speed system is more accurate, and the speed error can be controlled within ±5r/min.
8. The stopping torque can be set and displayed in real time during the extreme pressure test, which is used to assist the judgment of the PD value or for safety protection.
9. The real-time sample temperature is displayed on the LCD screen with a temperature control resolution of 0.1°C.
10. The test ball bowl automatically heats the oil sample, and when the sample reaches the set temperature, the motor is automatically started. After the test, the temperature control is automatically stopped and the motor is automatically turned off.
11. Simple and convenient operation and intuitive display, coupled with the measurement and automatic calculation software of the electron microscope. Make the test process faster, more accurate, convenient, intelligent and humane.
12. Simple and convenient bowl and chuck loading and unloading structure, labor-saving and durable.
13. Independent research and development of high-definition image data acquisition and processing system. Equipped with high-precision measuring microscope, image adapter mirror, image sensor camera, image processing system software and digital display measurement system. It is convenient to observe, measure, save and print the test results.
