High-Speed Hybrid Angular Contact Ball Bearings Lubricated by Kerosene Mist

Abstract

This paper presents some experimental research, carried-out on 7206C hybrid angular contact ball bearings lubricated by oil and kerosene mist. The monitored parameters are the friction moment of the testing bearing, and the testing device house temperature. The developed tests proved that the hybrid ball bearings lubricated by kerosene mist run with no problems at light load (200 N) and high speed (20,000 rpm). An equilibrium temperature less than 480 C was reached at 200 N axial load and 20 000 rpm. At 40,000 rpm, the friction moment and the temperature within bearings are continuously increasing, the test being stopped when a temperature of 60 0 C was reached on the house of the testing device.
