Bearing Tester

Equipment for fatigue testing and life testing for rolling bearings.

  • JSPS Type Ball Bearing Life Tester It is one of the standard bearing tester in Japan developed by the 126th Committee on Rolling Bearing Life in the Japan Society for the Promotion of Science (currently active as Technical Committee on Life of Rolling Bearings in the Japanese Society of Tribologists). A life test (fatigue test) is performed by applying a constant load to the test radial bearing and rotating it at a constant speed. The life distribution data and other research results obtained by this bearing tester are widely disclosed to the general public through reports, papers, and explanatory articles.
  • Multiple Radial
    Rolling Bearing Life Tester
    A life test (fatigue test) is performed by applying a constant load to multiple test radial bearings and rotating them at a constant speed. It is suitable as a platform for research for diagnosis because it targets versatile radial bearings.
  • Thrust Ball Bearing Life Tester A life test (fatigue test) is performed by applying a load to the test bearing (thrust bearing) and rotating it at a constant speed. Due to the structure of thrust bearings, all rolling elements are operated under a constant load. Therefore, It is suited to reliability assessment for bearing washer materials and rolling element materials because it is sensitive to the number of stress repetitions.
