Dalian Bearing Maintenance Tips: The Key to Extending Service Life

In the operation of mechanical equipment, Dalian bearings are key components, and their performance directly affects the overall operating status of the equipment. The correct maintenance measures are the key to extending the service life of bearings.

1、 Cleaning work

Cleaning is the foundation of bearing maintenance. If pollutants such as dust, impurities, and metal debris enter the interior of the bearing, they will exacerbate the wear of the bearing.

After running the equipment for a period of time, it is necessary to regularly clean the bearings. Firstly, professional cleaning agents should be used to remove oil and dust from the surface of the bearing. For areas that are difficult to clean, a soft bristled brush can be used to gently scrub them. During the cleaning process, avoid using sharp tools to prevent scratching the surface of the bearing. After cleaning, the bearings should be wiped dry with a clean cloth or blown dry with compressed air to ensure that there is no residual moisture or cleaning agent inside the bearings, as moisture can cause rusting.

2、 Lubrication management

Good lubrication is an important guarantee for the normal operation and extended service life of bearings.

Choosing the appropriate lubricant is crucial. Different types of bearings and working environments require different types of lubricants. For example, in high-temperature environments, high-temperature resistant lubricating grease is needed; In high-speed equipment, lubricants with good shear resistance should be selected.

It is also necessary to regularly check the amount of lubricant. If there is too little lubricant, the bearing will experience dry friction due to lack of lubrication, leading to increased wear; If there is too much lubricant, it can cause unnecessary waste and may lead to lubricant leakage, contaminating equipment. Generally speaking, after a period of operation, it is necessary to supplement an appropriate amount of lubricant to ensure that the bearings are always in good lubrication condition.

3、 Reasonable installation and disassembly

The correct installation and disassembly methods can avoid unnecessary damage to the bearings.

When installing bearings, ensure that the installation tools are clean and in good condition. During the installation process, excessive force or incorrect installation methods should be avoided, such as not directly tapping the outer or inner ring of the bearing. Instead, a specialized installation sleeve or press should be used for installation. At the same time, it is necessary to ensure the positional accuracy of the bearing installation and ensure that the fit between the bearing, shaft, and bearing seat meets the design requirements.

When disassembling bearings, the correct tools and methods should also be used. Firstly, the equipment should be stopped and the components connected to the bearings should be disassembled. Then use professional disassembly tools such as pullers to remove the bearing from the shaft or bearing seat. During the disassembly process, attention should be paid to protecting the raceway and rolling elements of the bearing to avoid damage.

4、 Regular inspection and maintenance

Regular inspection of Dalian bearings is an important means of promptly identifying problems and taking corresponding measures.

The inspection includes checking whether the appearance of the bearing is damaged or cracked; Whether the rolling elements are worn or deformed; Whether the sound of bearing operation is normal, etc. If any abnormal situation is found in the bearing, it should be repaired or replaced in a timely manner.

In addition, it is necessary to inspect and maintain the working environment of the bearings. For example, to ensure good heat dissipation of the equipment and avoid bearing damage due to high temperature; Check whether the sealing device of the equipment is intact to prevent dust, moisture and other pollutants from entering the interior of the bearing.

In short, the maintenance of Dalian bearings is a meticulous and important task. By doing a good job in cleaning, lubrication, reasonable installation and disassembly, as well as regular inspection and maintenance, the service life of bearings can be effectively extended, the operating efficiency of equipment can be improved, the maintenance cost of equipment can be reduced, and strong guarantees can be provided for the production and operation of enterprises.
