HEF USA Home

 

We have 50 years experience in the study of industrial friction
and wear problems.  Our 2000th study was completed in 2000.

The H.E.F. Tribology study team has skills in mechanics,
components design, materials science, and metallurgy.

In addition to our technical skills, you can expect:

  • Adaptability and reactivity
  • Respect of the objectives
  • Confidentiality
  • Consideration of all possible solutions
    (geometrical design, lubrication, choice of materials,
    surface finish, surface treatments)

CREDENTIALS

  • Over 50 years of experience in providing solutions
    to friction and wear problems
  • Member ASIRDI (Association of Independent
    Research and Development Companies)
  • Over 2000 industrial studies completed
  • Leaders or participants in international cooperatives’
    research programs (BRITE/EURAM, EUREKA, etc.)
