Precautions for maintenance of self aligning roller bearing after installation

According to the relevant data, the damage during bearing installation accounts for 20% of the bearing damage. How can we reduce the damage during bearing installation? Here is a detailed introduction.
When installing self-aligning roller bearings, there are specific requirements for the site. The site must be kept dry and clean, and iron filings, sand, dust, moisture, etc. must be strictly prevented from entering the bearing.
The common installation tools of bearings include hammer, copper bar, sleeve, special base plate, screw clamp, press, etc. the measuring tools include vernier caliper, micrometer, dial indicator, etc., but different tools should be selected according to different bearing models.
After selecting the right tools, the bearing can be installed. During installation, attention should be paid to whether there are bumps, rust layers, wear debris, sand particles, dust and soil. If there are any, it will cause installation difficulties. It is necessary to keep the assembly surface of self-aligning roller bearing and the surface of parts matched with it clean.
In addition to cleaning the surface of bearing assembly and mating parts, it is also necessary to pay attention to whether there is corrosion layer on the surface of journal, bearing housing hole, shoulder end face, and connecting parts such as bushing, washer, end cover, etc? If there is any, it can be filed off, polished with fine emery cloth, and then installed.
Rolling bearing is a precision part, so its use should be carried out with corresponding caution. No matter how high performance bearings are used, if they are not used properly, the expected high performance will not be obtained. Precautions for the use of self-aligning roller bearings are as follows:
1. Use with care
In the use of the bearing to give a strong impact, will produce scars and indentation, become the cause of the accident. In serious cases, it will crack and fracture, so we must pay attention to it.
2. Keep bearings and their surroundings clean
Even the small dust that can't be seen by the eyes will bring bad effect to the bearing. Therefore, to keep the surrounding clean, so that the dust does not invade the bearing.
3. Use proper operation tools
Instead of using existing tools, appropriate tools must be used.
4. Pay attention to the corrosion of the bearing
When operating the bearing, the sweat on the hand can be the cause of rust. To pay attention to use clean hands, it is best to wear gloves.
