MULTI-FOUR BALL TEST MACHINE

The Multi-Four Ball Test Machine incorporates both the Four Ball EP (extreme pressure) and the Four Ball Wear testers into one computer operated machine. Increasing demands in Tribology testing have required the need for higher accuracy of controlled variables, increased reproducibility and repeatability, more dynamic ways to uncover data, and more control capacity. This new machine is based on a revolutionary new concept, which linearizes the specimen-applied load in both wear and extreme pressure thresholds. This linear loading concept broadens the machine's capabilities, accuracies and the spectrum of test evaluation. Test variables include: load, RPM, time, and temperature. The M-4 can run other specimen configurations. PTI, Inc. latest specimen geometry is referred to as the Twist Compression Test for evaluating forming fluids. This adapter can also be used as a thrust washer test for evaluating a wide range of lubricants and materials.

EPSILON LINEAR PRECISION TEST MACHINE

We have been using PTIs Multi-Four Ball Test Machine and their Epsilon Linear Precision Test Machine for over 5 years. PTI instruments have provided us with product developments that we could not have achieved any other way. These are the most wonderful instruments in the world because they have saved us a considerable amount of time and money. In addition, the graphing capabilities of PTIs machines have greatly enhanced our product presentations. Everyone in our industry should have these wear testers. They are simply the best.

PTI is one of the most knowledgeable tribological and analytical companys in our industry. We recently purchased PTIs Multi-Four Ball Test Machine and have been very happy with the results. PTI has responded to any and all of our questions about the machine and the in-house training they provided has been very helpful. PTI is the only company that has come up with any innovations in lubricant testing equipment during the past 15 years. The fact that PTIs machines are fully-integrated with a computer system gives us real-time data acquisition. This allows us to be more efficient with our time and provides us with data that can be used for both marketing and technical purposes.
