⚙️product description:
Structural features: A double-sided sealing structure is adopted, usually consisting of double steel plates as dust-proof covers, which can effectively prevent dust and impurities from entering the bearing interior, ensuring the normal operation and service life of the bearing.
Materials: The bearing material is generally high-carbon chromium bearing steel (GCr15), which has good wear resistance and strength, capable of meeting the working requirements of the bearing under high-speed and high-load conditions. The cage material is mostly stainless steel or made by steel plate stamping.

Space adaptability: The ultra-small size of 2×5×2.3mm and the lightweight design of 0.12g make it a "standard bearing" for miniature devices, especially suitable for products that are sensitive to volume and weight such as printers and drones.
Protection and durability: The ZZ dust-proof cover design ensures that the bearing can operate stably in dusty environments (such as textile machinery, food processing equipment), and the stainless steel model can withstand mild corrosion, suitable for medical device disinfection scenarios.
High rotational speed advantage: With grease lubrication, the maximum rotational speed is 85,000 rpm, far exceeding that of ordinary small bearings, meeting the high-speed rotation requirements of miniature motors, gyroscopes, etc.
