Description

Technical Field

[0001] This utility model relates to the technical field of bearing sealing testing equipment, and specifically to a bearing sealing performance testing device. Background Technology

[0002] Sealed bearings are based on ordinary bearings with the addition of sealing components. They mainly consist of an inner ring, an outer ring, rolling elements (balls or rollers), a cage, and a seal. With industrial development, product manufacturing specifications are becoming increasingly higher, and there are strict mandatory requirements for the quality and sealing performance of bearings.

[0003] In related technologies, the sealing ring in a sealed bearing plays a sealing role, preventing the internal lubricating grease from flowing out and preventing external particulate matter and moisture from entering, thus providing a good working environment for the bearing and playing an important role in extending the life of rolling bearings.

[0004] If the bearing seal is poor during production, external impurities and moisture will enter the bearing after subsequent assembly, causing wear on the rolling elements, raceways, and cage, thus affecting the bearing's rotational accuracy. Therefore, how to develop a device to detect the bearing's sealing performance to ensure good bearing sealing and improve bearing quality is a problem that many bearing manufacturers urgently need to solve.
