628/8-2Z

The 628/8-2Z is a single-row double-sided dust-proof deep groove ball bearing. Its core function is to provide high-stability, low-maintenance, high-speed rotational support for various small-sized equipment with limited space. With a compact structure of 8mm inner diameter, 16mm outer diameter, and 5mm width, it meets the installation requirements of small components. The -2Z suffix design of the double-sided stamped steel dust-proof cover enables it to effectively prevent dust and other impurities from entering and prevent internal lubricating oil leakage, significantly extending the service life of the bearing in various working conditions, eliminating the need for frequent grease replenishment maintenance. This bearing can withstand both radial loads and small bidirectional axial loads. The deep groove structure, combined with high-quality bearing steel material and suitable lubricating oil, not only has a low friction coefficient, reducing noise and vibration during equipment operation, but also possesses reliable mechanical properties. The reference rotational speed is up to 90,000 r/min, and the maximum rotational speed is up to 45,000 r/min. It can be used in both household motors, small household appliances, and other conventional scenarios, as well as in electric tools, gearboxes, and other components with certain rotational speed requirements. It can also be used in industrial scenarios such as laboratory mixing equipment, plastic and rubber industries, and small machinery in related fields. With high adaptability, it provides efficient and stable support for various small rotating mechanisms.
