Welcome to Lewis Research, Inc.

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 the 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 altogether. 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.

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 inflammable 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.
