Precautions when assembling and disassembling bearings

(1) Ensure cleanliness of bearing and assembly/disassembly environment

The American bearing industry once emphasized to users that "no dust is allowed in the watch, and the bearing is a much more precise mechanical element". 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 effect. So the bearing itself. The installation position, tools used, cleaning oil, lubricating oil, operators and the surrounding environment shall be kept highly clean, so as to set up a special assembly and disassembly site.

(2) Do a good job of rust prevention and dust prevention of bearings

The bearing can only be opened and cleaned immediately before installation; After the bearing is removed from the host, if it is still valuable for further use, it should be cleaned and sealed immediately or installed in the host to be used. If it is really necessary to keep it until the next day, it must be placed in a clean place or sealed, and the strict cleanliness of relevant tools and oils must continue to be guaranteed.

(3) Strictly ensure the anti rust conditions of bearings

It is absolutely forbidden to touch the bearing with bare hands (the quick corrosion test can clearly show the fingerprint like corrosion trace of the place touched by human hands on the bearing). Only a piece of clean white paper without corrosion can be used to hold the bearing, or the hand can be fully washed off and coated with high-quality mineral oil, and then the bearing can be directly contacted with hands for operation, especially in summer, especially in the rainy season.

(4) Use appropriate assembly and disassembly methods and tools

Select appropriate loading and unloading methods and tools according to the type characteristics and matching tightness of the bearing, and use special tools easily. Pay attention not to use cloth, yarn or short fiber materials that are easy to drop silk strands to wipe the bearing or tools used.

(5) The assembly and disassembly shall be conducted in a civilized manner

As the bearing is a precision mechanical element with high surface hardness, and the contact part is "point line contact", it is very easy to cause indentation and bruise on the rolling surface during rough handling, which must be strictly prevented.

(6) Assembling and disassembling shall be carried out by technicians who are proficient in bearing application
