The disassembly of the bearing is carried out regularly, and it is carried out when the bearing is replaced. After disassembly, if you continue to use it, or if you need to check the condition of the bearing, the disassembly must be carried out as carefully as during installation. Then when disassembling the bearing, you need to pay attention not to damage the bearing parts. The Jiangsu bearing manufacturers will tell you how to properly disassemble the bearing.

It is also important to design and make disassembly tools as needed. When disassembling, study the disassembly method, sequence, and investigate the matching conditions of the bearings according to the drawings to find the foolproof operation.

Disassembly of the outer ring The outer ring with interference fit is provided with several outer ring extrusion screw screws on the circumference of the casing in advance, and the screws are evenly tightened on one side while being disassembled. These screw holes are usually covered with separate bearings such as blind plugs, tapered roller bearings, etc. Several cutouts are set in the housing blocking shoulder, and they are disassembled with a press using a pad or lightly tapped.

Disassembly of the inner ring can be pulled out easily with a press. At this time, pay attention to the inner ring to withstand its pulling force. Moreover, the pull-out clamps shown are also mostly used, no matter which kind of clamps, they must be firmly clamped to the side of the inner ring. For this reason, it is necessary to consider the size of the shaft shoulder, or to study the groove on the shoulder so as to use a drawing clamp.


The inner ring of large bearings is disassembled by hydraulic method. Oil pressure is provided through the oil hole provided in the bearing to make it easy to pull. For bearings with large widths, the hydraulic method is used in combination with the pull-out clamp for disassembly.

The inner ring of NU and NJ cylindrical roller bearings can be disassembled by induction heating. A method of heating the local part in a short time to expand the inner ring and then drawing. Where a large number of bearing inner rings need to be installed, induction heating is also used.
