What is the service life of CC Tiebao self-aligning roller bearings

The service life of CC type stamped steel cage self-aligning roller bearings is a relatively complex issue, which is influenced by various factors. The following is a detailed analysis of its service life and influencing factors:

1、 Prediction of service life

It is crucial to scientifically predict the service life of CC type self-aligning roller bearings, taking into account various factors such as mechanical type, diversity of working conditions, and reliability requirements. The service life of bearings may vary for different types of machinery and application scenarios. Here are some common estimates of service life:

Instruments and equipment that are not frequently used: The recommended lifespan is between 300 and 3000 hours.

Short term use or intermittent operation of machines, such as manual machinery, installation cranes, and automatic feeding devices, are recommended to have a service life of 3000 to 8000 hours.

Machinery that is used intermittently but will cause serious consequences, such as auxiliary equipment in power plants, assembly line transmission devices, belt conveyors, and workshop cranes, are recommended to have a service life of 8000 to 12000 hours.

Machines that run for 8 hours a day but not at full load, such as motors, general gear units, crushers, cranes, and other general machinery, are recommended to have a service life between 10000 and 25000 hours.

Machinery that works at full load for 8 hours a day, such as machine tools, construction machinery, and centrifuges, are recommended to have a service life of 20000 to 30000 hours.

Machinery that works continuously 24 hours a day, such as compressors, pumps, motors, and gear devices, are recommended to have a lifespan of up to 40000 to 50000 hours.

2、 Factors affecting service life

Lubrication situation: Insufficient or improper lubrication may cause component scratches or severe bearing deformation. Therefore, improving the lubrication system and timely and appropriate replenishment or replacement of lubricants are key to extending the life of bearings.

Operation specifications: Improper installation, operation, or disassembly of bearings may cause deformation or damage to the cage. Using appropriate operating, installation, and disassembly tools, as well as using qualified and standardized genuine bearings, can avoid such problems.

Rust and corrosion: Contact with water may cause bearing components to corrode and rust, and bearings damaged by rust may peel off during operation. Regular inspection of the seal to ensure good sealing effect, as well as proper storage of bearings, can effectively prevent rust and corrosion.

External materials: abrasive particle contamination and debris intrusion may cause wear, scratches, and dents on the bearing working surface. Removing invading particles and debris, replacing lubricants, and inspecting sealing systems can reduce such damage.

Bearing eccentricity: Eccentricity, tilting, or excessive load may cause geometric stress concentration or surface peeling. The use of precision machined bearing seats and shoulders, as well as the use of thermal sensors to monitor the working temperature of bearings, can prevent such problems.

In addition, the material, manufacturing process, and usage environment of bearings can also affect their service life. Therefore, when selecting and using CC type self-aligning roller bearings, the above factors should be comprehensively considered to ensure the normal operation of the bearings and extend their service life.

3、 Maintenance suggestions

Regular inspection: Regularly inspect the bearings, including lubrication, sealing, wear, etc.

Timely replacement: When cracks, fractures, jamming, severe wear and other problems are found in the bearings, new bearings should be replaced in a timely manner.

Proper storage: For unused bearings, they should be stored in a dry, ventilated, and non corrosive environment.

In summary, the service life of CC type stamped steel cage self-aligning roller bearings is affected by various factors, but through scientific prediction, reasonable use, and maintenance, its service life can be extended and its reliability can be improved.
