TRIS USA is globally recognized for manufacturing carbon brushes for DC motors, and for over 31 years! Our worldwide reputation is supported by our continuous efforts in Research & Development. We start early in research, using the science/technology of Tribology, which is the study in surface friction, abrasion, and lubrication. TRIS, whose name is derived from the word Tribology System, manufactures small, but essential, electric motor components. We recognize our responsibility as a global citizen, and are continually striving to reduce the environmental impact of the work we do to achieve an environmentally-friendly business with the products we create.
