Since the first half of 2016, the UTCRS research team composed of faculty and students designed and fabricated an efficient and compact Four Bearing Tester that can be used to perform long‐duration service life tests to characterize bearing performance and assess the quality of the bearing steel. This four bearing tester is housed in a specially designed environmental chamber that can mimic ambient conditions as low as ‐40°F and as high as 150°F. The addition of this tester to the UTCRS infrastructure provides enhanced research capabilities that can accelerate projects of interest to the rail industry.
