Product Description
The four-ball tribometer is used to determine the friction and wear properties of lubricant, including oil and grease, under varying load conditions. It accurately assesses the load-bearing capacity of lubricants through several key metrics: maximum non-seizure load (Pb), sintering load (Pd), and comprehensive wear value (ZMZ). This machine allows for long-term wear tests without compromising the precision of the Pb measurement, even after multiple Pd tests. It can also measure the coefficient of friction while recording friction force and temperature curves. For enhanced precision, the system can be equipped with high-accuracy measuring devices to calculate and display wear scar diameters on-screen. With specialized attachments, these friction and wear testing machines can perform end-face wear tests and simulate material behavior under specific conditions.

Applications
This friction and wear tester is widely used in evaluating lubricating oils, greases, and components such as tapered roller bearings.
Features
The four ball friction and wear testing machine (referred to as the four ball machine) is the most commonly used instrument for evaluating the extreme pressure anti-wear and anti friction properties of various lubricating materials, as well as for conducting frictional research. It has outstanding advantages such as simple operation, low experimental cost, and fast measurement speed. It is widely used in the performance evaluation of base oils, additives, compound formulations, and oil quality supervision and inspection. It is also the most commonly used tool for conducting frictional theory research.
Basic Functional Characteristics
- Test the maximum non stick load Pb, sintering load Pd, comprehensive wear value ZMZ, D value and other indicators of the lubricant
- Long term wear resistance test of lubricants, determination of friction coefficient
- Special test for lubricating oil: friction coefficient step test (SH0762/ASTM5183)
- Rapid expansion of KRL lubricant shear test (SH0845)
- Improve lubricating oil process and control the optimal economic ratio of formula
- Fully automatic: with a high degree of automation, after installing the sample, you can enter the fully automatic test (only 2 keys are needed)
- Accuracy: load and friction force can be self calibrated during startup, and friction force can also be equipped with dual sensors to improve absolute accuracy
- Grinding spot: the grinding spot diameter directly displays the reference value and quickly locks the level (without the need for a microscope)
- Judgment: PB and PD multi-directional online judgment to improve accuracy and equipment service life (ms level protection)
- Extension function: it can quickly carry out step tests for friction coefficient (SH0762/ASTM5183) and convert KRL lubricating oil shear tests (SH0845)
- Quick comparison: develop new oil products without the need for a microscope, quickly calculate the comprehensive wear performance ZMZ index

This machine is suitable for dynamic balancing of disc-shaped rotating parts on a single surface. It is an ideal equipment for dynamic balancing of fan blades, ventilation fan blades, automobile flywheels, clutches, brake discs, brake hubs, hydraulic couplings and other parts. You only need to replace the fixtures for installing the workpieces to perform balancing checks. The industrial control computer processes data, and the color screen displays the unbalance value, phase angle and real-time speed in real time. It is equipped with an industrial cabinet and the balancing machine system composed of the mechanical part is convenient for parameter storage and printing.
