Lewis Research, Inc. is a tribological testing facility and test equipment manufacturer providing high quality tribology equipment and service to clients worldwide. Lewis Research, Inc. was founded in 1985, but our staff has been involved in the tribology field for over 50 years. LRI has clients in 31 US states and 9 countries including machines in Netherlands (3 locations), Germany, Italy, Belgium, United Kingdom, China (2 locations), India, and Mexico.

Our machines are built to test the friction and wear of plastics and other materials for use as bearings, seals, piston rings, gears and other sliding applications. We stake our reputation on the results we produce and the tribological machines we use to achieve them.

Our team can provide both standardized tribological testing and unique tests that are customized to fit your specific project - if one of our existing machines isn't equipped to deliver what you need, we can adapt it or design a new piece of equipment all together. Our staff welcomes the opportunity to customize both equipment and programs to meet your tribological needs.

Lewis Research, Inc. also offers a number of tribometer machines for sale - interested parties should contact us for more information.

To learn more about tribometer testing or to start talking about what Lewis Research, Inc. can do for you, please contact us today.


1) We can supply equipment requiring up to 25,000 pounds of applied load.  This higher loading is achieved through the use of hydraulics.  We have delivered two machines using hydraulic loading for two different applications.

2) Thrust bearing and/or pin-on-disc testing in flammable liquids or gases.  We have completed two programs for clients on the LRI-1a.  One was conducted in Jet A Fuel and the other was run in a Natural Gas environment.
