disassemble

The disassembly of bearings is a regular maintenance and is carried out during bearing replacement. After disassembly, if it is necessary to continue using or to check the condition of the bearings, the disassembly should be carried out with the same care as during installation. Be careful not to damage the various parts of the bearing, especially the disassembly of interference fit bearings, which is difficult to operate.

The disassembly of the outer ring with interference fit requires setting several outer ring compression screws on the circumference of the shell in advance, tightening the screws evenly while disassembling. These screw holes are usually covered with blind plugs, tapered roller bearings, and other separable bearings. Several cuts are made on the shoulder of the housing cover, and they can be disassembled using pads, a press, or gently tapped. The disassembly of the inner ring can be easily done by pulling it out with a press. At this point, it is important to ensure that the inner ring bears its pulling force.

At the factory, the bearings are coated with an appropriate amount of anti rust oil and packaged with anti rust paper. As long as the packaging is not damaged, the quality of the bearings will be guaranteed. However, for long-term storage, it is advisable to store on a shelf 30cm above the ground under conditions of humidity below 65% and temperature around 20 ℃. In addition, the storage location should avoid direct sunlight or contact with cold walls.
