READ MOREThe material selection of self-aligning ball bearings is crucial to their performance, durability and reliability:
Outer and inner rings: Usually made of high-carbon chromium bearing steel, such as GCr15 or AISI 52100, these materials have high hardness and good wear resistance.
Rolling elements: High-carbon chromium steel is also used to ensure the wear resistance and load-bearing capacity of the rolling elements.
Cage: A variety of materials can be used, such as steel plate, brass, engineering plastics, etc. The choice depends on the specific requirements of the application and the operating conditions of the bearing.
The choice of different materials affects the corrosion resistance, temperature resistance, weight and cost of the bearing.
Seal and lubrication of self-aligning ball bearings are crucial to extend their service life and reduce maintenance:
Seal: Seals can prevent contaminants from entering the bearing while retaining lubricants. Seal types include metal seals, rubber seals and lip seals.
Lubrication: Lubrication can reduce friction and wear between rolling elements and raceways. Lubrication methods include oil lubrication and grease lubrication. Grease lubrication is generally used for low to medium speed applications, while oil lubrication is suitable for high speed or high temperature applications.
Proper sealing and lubrication can significantly improve the performance and life of bearings.
The installation of self-aligning ball bearings has an important impact on their performance and life:
Alignment: Since the self-aligning ball bearing has the ability to self-align, it can automatically compensate for a certain degree of centering error. However, correct alignment can still improve the life of the bearing and reduce noise.
Installation force: During the installation process, excessive force should be avoided, which may cause damage or deformation of the bearing.
- Installation tools: Use appropriate tools and methods for installation to avoid damaging the seal or cage of the bearing.
Correct installation can ensure the performance and reliability of the bearing during operation.
