Are the ball bearings able to withstand the sustained workload?

Yes, ball bearings can withstand continuous working loads, especially when selected and maintained appropriately. The following are some key factors that make ball bearings suitable for continuous working loads:
Design and material selection: Ball bearings are usually made of high-strength materials, such as high carbon chromium steel, stainless steel, or ceramics. These materials have high hardness and wear resistance, and can maintain stable performance under long-term loads.
Lubrication: Proper lubrication is crucial to ensure that ball bearings can withstand continuous working loads. Lubricants can reduce friction and wear, prevent overheating, and extend the lifespan of bearings. Regular inspection and replacement of lubricants are necessary steps to maintain bearing performance.
Load distribution: The design of ball bearings ensures that the load is evenly distributed between the ball and raceway, which helps to reduce local stress concentration and extend the life of the bearing.
Pre load and internal clearance: By correctly pre load and controlling internal clearance, ball bearings can maintain stable performance under working loads, reduce vibration and noise, and prevent sliding or slipping between the balls and raceways.
Heat treatment and surface treatment: Many ball bearings undergo heat treatment and surface treatment to improve their wear resistance and fatigue resistance. These processing methods can significantly enhance the performance of bearings under continuous working loads.
Proper installation and alignment: Proper installation and alignment can ensure smooth operation of bearings under working load, avoiding additional stress and wear caused by improper installation.
Sealing and protection: Ball bearings are usually equipped with seals or protective devices to prevent dust, dirt, and other pollutants from entering the interior of the bearing. These measures help maintain the cleanliness and lubrication of bearings in harsh environments, thereby improving their performance and lifespan under continuous loads.
In summary, ball bearings have multiple advantages in design, material selection, lubrication, and maintenance, enabling them to withstand continuous working loads. Through proper selection and maintenance, ball bearings can provide long-term reliable performance in various applications.
