A common way of preloaded roller bearing

When is preloaded bearing assembly, give a axial force bearing inner and outer ring, to eliminate the bearing clearance, and make contact with the inner and outer ring roller early deformations. Preloaded can improve bearing stiffness and rotation accuracy at work. Pre-tightening load size, should according to the requirement of load condition and use: if the main purpose is to reduce the vibration of the supporting system and improve the rotation accuracy, select small pre-tightening force; If in order to increase the stiffness of the supporting system, should choose larger pre-tightening force. Usually, when we are in the rolling bearing preloaded will adopt the following four ways: 1, with the bearing inner and outer washer thickness difference preloaded. 2, narrow the two bearing inner ring or outer ring. 3, adjust bearings taper hole inner ring axial position preload. Four, spring preload.
