Timken Test Machine
The extreme pressure friction testing machine mainly consists of a main frame, a spindle transmission system, a test force loading mechanism, a lubricant supply and recovery mechanism, a sample fixture, and a control and measurement sensing system. Under the precise closed-loop control of the computer measurement and control system, the testing machine can achieve uniform and constant loading of test force, precise rotation of the spindle, and precise oil supply.
Application
Alemken extreme pressure friction testing machine is mainly used to evaluate the extreme pressure performance and abrasion resistance of various tear oil and grease, etc. Its specific uses include but are not limited to:
Evaluating the extreme pressure bearing capacity of lubricating media: The Timken testing machine can evaluate the bearing capacity of lubricating media such as lubricating oil and grease under extreme conditions by simulating the friction and wear process under extreme pressure conditions. This is of great significance to the research and specification of industrial oils and fats.
Distinguish the performance of EP additives: Through the test of Timken testing machine, it is possible to distinguish the low, medium and high extreme pressure performance of different EP(extreme pressure) additives, which provides a scientific basis for the optimization of lubricant formulation.
Material properties research: In addition to lubricating media, Timken testing machine can also be used for a variety of coatings, coatings, metal, non-metal and other materials performance research, especially their wear resistance and friction coefficient.
Testing Standards
ASTM D 2509:Standard Test Method for Measurement of Load-Carrying Capacity of Lubricating Grease (Timken Method)
ASTM D 2782:Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Fluids (Timken Method)
GB/T3142:Standard test method for determination of load-carrying capacity of lubricants—Four-ball method
SH/T0204:Test Method for Determining Anti-wear Properties of Lubricating Grease (Four-ball Machine Method)
Timken extreme pressure friction testing machines are usually tested in accordance with the following standards and specifications:
ASTM D2509: This is a standard developed by the American Society for Materials and Testing (ASTM) to evaluate the performance of lubricants and lipids under extreme pressure conditions. The test methods and results evaluation of Timken testing machines shall be carried out in accordance with this standard.
ASTM D2782: Also developed by ASTM to evaluate the performance of certain types of lubricants under extreme pressure conditions.
Other relevant standards; Depending on the specific application area and test requirements, other relevant standards and specifications may also be involved. For example, in China, the testing of the Timken testing machine may also require compliance with relevant national standards such as GBT or industry standards.
In addition, different types of Timken testing machines may have different technical parameters and scope of application, so before testing, you should carefully read the equipment manual to understand the specific performance and test requirements of the equipment to ensure the accuracy and reliability of the test results.

Accessoriess
The core components of the Timken testing machine (Timken wear and lubricant testing machine) include bearing components (such as cylindrical roller bearings, deep groove ball bearings, tapered roller bearings, mounted bearing units, flat belt idlers, etc.) and special testing components (such as wear testing modules and lubricant supply system components).
Test Procedures
Sample Preparation: Preheat the sample to 37.8℃ ± 2.8℃.
Test Start: A steel test ring rotates in close contact with a steel test block at a speed of 123.71 m/min ± 0.77 m/min (405.88 ft/min ± 2.54 ft/min).
Determining Scratch Value and OK Value: The minimum mass (weight) required for the oil film between the rotating test ring and the stationary test block to rupture, causing seizure or scratching, is the scratch value. The maximum mass (weight) required for the oil film between the rotating test ring and the stationary test block to not rupture, without causing seizure or scratching, is the OK value.
Test Result Analysis: Analyze the extreme pressure performance of the lubricating oil based on the test results, including indicators such as wear, friction, and abrasion resistance.
