The work aims to solve the problem of vibration and impact in transportation caused to the existing package of precision bearing, which tends to result in the quality deterioration of surface between its contact surfaces. A packaging method for precision bearing in rigid-flexible combination was proposed to eliminate the clearance between rollers and inner ring through pre-tightening force positioning device. The packaging pieces were protected combined with the buffering cushion. Based on stress-strain theory, the pre-tightening force positioning device was designed, and the processing of such device contacting with the bearing was simulated with FEM software. The bearing stress change and the mechanical representation of pre-tightening device during the said process were studied. The simulation results showed that the clearance was eliminated after the positioning device applied pre-tightening force on the bearing, and the elastic deformation of the bearing was acceptable. Through the free-fall test done on the whole packaging pieces, the measured impact acceleration borne by the bearing was less than 50G. According to the detection, the bearing contact surface was not damaged. The proposed packaging method can protect the precision bearing.
