Benchtop Four Ball Wear and EP Tester

Benchtop Four Ball Wear and EP Tester

The K93170 Four Ball Wear and EP Tester is designed as per ASTM standards to conduct tests to determine the coefficient of friction of lubricants, wear preventative (WP) and extreme pressure (EP) properties of lubricating oils and greases under a variety of test conditions. This instrument can also be used to determine load carrying properties by the load wear index and the weld point method.

 

The test load is directly controlled through a software-based close loop servo-pneumatic drive, which enables precise control over the load application. The user can choose between different loading sequences, such as constant load test, progressive loading in increment or decrement, and also step-wise loading in increment or decrement. This dynamic load control system with speed control can also be used for understanding the Stribeck curve phenomena, which is not possible with the conventional dead weight loading technique.

latest addition to the Koehler Flash Tester family of products.
This unit is robustly designed using state-of-the-art technology to
allow for seamless testing in accordance with ASTM procedure.
The system software runs on an integrated processor PC running
the latest Windows operating system. The 10.4” touch screen
interface fully displays all operator parameters and results on a
single screen. Data results can be stored on the local hard drive.
An integrated Dual Fan System directly cools the test cup and the
environment around the cup.

Test Method

A ball of specified diameter (12.7 mm) rotates at a particular velocity and comes in contact with three similar stationary steel balls immersed in the lubricant. As per ASTM standards, the upper ball is rotated up to 2000 RPM and the lubricant can be heated up to 200 degrees C. An axial force up to 1000 kg is applied through servo-pneumatic close loop loading mechanisms. Friction force between the rotating ball and the three stationary balls is measured through a digital load cell mounted in precise location for better resolution, and all the process variables like lubricant temperature, normal load, friction force, coefficient of friction, and rpm are measured and acquired through online data acquisition software through an integrated PC.
