Abstract. This work presents a study of the technology of bearings heat treatment for mining machinery is an important scientific problem, the solution of which will increase their service life. Bearings are often subjected to significant loads. They work in polluted humid atmosphere and at high temperatures.

The main cause of bearing damage is the development of contact fatigue processes. The paper suggests ways of solving the problem of improving the contact endurance of corrosion-resistant ball bearings.

Keywords: ball bearings, bearing corrosion-resistant steels, vacuum heat treatment, hardness, contact endurance.
