Abstract：In order to analyze and evaluate the loading capability of bearings proir to their use under specific working conditions， based on a certain type of high speed angular contact ball bearings in the performance of the specific conditions， conducts simulation research respectively in terms of sharp deceleration process， unsteady lubrication state， maintained dynamic characteristics and strength and best pre-tightening force. The phenomenons affecting steady working of the bearrings are analyzed and the rationalisation proposals for the actual engineering use of the bearings of this type are given.

Keywords：bearing；high-speed；performance；pre-tightening force；vibration
