Learning Objectives

  • Upon completion of the course, participants will be able to:
  • understand the main points on grease: structure, properties, production modes, testing methods and performance characterization, different types of greases and criteria for the choice according to the applications,
  • know the applications of grease other than bearings (gears, automotive and industrial transmissions, couplings),
  • recommend a bearing grease according to the operating conditions and to calculate the lubrication intervals and the life time,
  • recognize the bearing failures and identify the origins.

Ways & Means

  • Interactive exercises with the teacher for the determination of a bearing grease, the lubrication intervals, the lifetime calculation of bearings according to the operating conditions.
  • Interactive exercises of questions-answers between the participants using sets of play cards to synthetize the essential points of the lectures.
