What should be paid attention to when disassembling deep groove ball bearings?

What should be paid attention to when disassembling deep groove ball bearings? During the maintenance of mechanical equipment, how many mechanical deep groove ball bearings need to be disassembled, maintained and reinstalled for use, and what should be paid attention to when disassembling the bearings? In the face of this problem, tell us what to pay attention to when disassembling deep groove ball bearings

1. To ensure the cleanness of the bearing and the assembly and disassembly environment, the bearing is a precision part. The entry of dust will damage the integrity of the lubricating oil film and cause contact potential difference corrosion, which is a common factor causing wear, fatigue and corrosion and has a very bad impact. Therefore, the bearing itself, the installation position, the tools used, the cleaning oil, the lubricating oil, and the surrounding environment should be kept highly clean, and special assembly and disassembly sites should be set up.

2. Do a good job of rust prevention and dust prevention of the bearing. Before the installation of precision bearing, open the package and clean it. If the precision bearing is still valuable for further use after it is removed from the machine, it should be cleaned and sealed immediately or installed in the machine for further use. If it is really necessary to keep it until the next day, it must be placed in a clean place or sealed.

3. Strictly ensure the anti rust conditions of the bearing. It is forbidden to touch the precision bearing directly without cleaning it. You can hold the bearing with a piece of clean white paper without corrosion, or you can directly touch the bearing with your hand after fully washing away the sweat and grease and coating it with mineral oil.

4. Proper assembly and disassembly methods and tools shall be used according to the type characteristics and matching tightness of precision bearings. Appropriate assembly and disassembly methods and tools shall be selected, and special tools shall be used. Pay attention not to use cloth, yarn or short fiber materials that are easy to drop silk strands to wipe precision bearings or tools.

5. The assembly and disassembly shall be carried out in a civilized manner. As the bearing is a precision mechanical element with high surface hardness, and the contact part is point to line contact, it is very easy to cause indentation and bruise on the rolling surface during rough loading and unloading, which must be strictly prevented.
