Everyone knows that in the process of using the bearing, regular maintenance work must be carried out in order to achieve the expected effect of the bearing. However, in the maintenance work, it is very likely that the bearing needs to be disassembled and installed, so that the bearing continues to operate well, in order not to Let the bearing get damaged, we must use the correct method when disassembling the bearing.

Analysis of bearing inner and outer ring removal method

To remove the interference fit outer ring of the outer ring, install a few outer ring extrusion screw screws on the circumference of the outer casing. For example, the printing machine bearings are equally tightened on one side and disassembled. These screw holes are usually covered with blind plugs, tapered roller bearings and other separate bearings. The printing machine bearings are provided with several cuts on the shoulders of the outer casing. Use the spacers, disassemble them with a press, or gently tap and disassemble them.

The removal of the inner ring is the easiest to pull out with a press. At this time, pay attention to let the inner ring withstand its pulling force. Moreover, the pull-out fasteners shown are also mostly used, and regardless of the type of fixture, they must be firmly stuck on the side of the inner ring. To do this, consider the size of the shaft shoulder or study the groove at the shoulder to use the pull fixture.

Large bearing and cylindrical roller bearing removal method

The inner ring of large bearings is dismantled by hydraulic method. By placing oil pressure on the oil hole of the bearing, the press bearings are made to make it easy to draw. The bearing with a large width is used in combination with the hydraulic chucking method and the drawing device.

The inner ring of the cylindrical roller bearing can be removed by induction heating. A method of heating a part in a short time to expand the inner ring and then pull it. In the case where a large number of such bearing inner rings are required to be installed, induction heating is also used.
