In order to solve the problem of cushion packaging of high precision bearing, HL-1029 organic silica gel was used to make the cup cushion of the high precision bearing. First, the HL-1029 organic silica gel material test piece was made, and its uniaxial tensile test was carried out. The test results were analyzed and calculated, and it was found that the least thickness of HL-1029 organic silica gel used as cushion packing liner of the high precision bearing should be 12 mm. Then, the drop simulation test was carried out with the high-precision bearing packed with 12 mm and 17 mm thick organic silica gel cushion, and the stress and strain nephogram of the shaft during the drop was obtained. According to the test results, the HL-1029 organic silica gel cushion could effectively protect the high-precision bearing.
