628/5-2Z

The 628/5-2Z is a small-sized general-purpose double-sided dust-proof deep groove ball bearing. Its core function is to provide dust-proof, wear-resistant, long-lasting and stable rotational support for small-sized equipment in compact spaces, suitable for various scenarios in industrial production and civilian use that have basic requirements for cleanliness and low maintenance. This bearing maintains a compact size of 5mm inner diameter, 11mm outer diameter and 3.5mm width, perfectly fitting the narrow installation space of miniature motors, small transmission mechanisms and other equipment. The raceway and balls are made of high-carbon chromium bearing steel, combined with a metal thin plate cage, featuring high hardness, wear resistance and structural stability, capable of handling regular loads and slight vibrations. The key upgraded double-sided metal dust-proof cover (2Z code) design can effectively prevent dust and impurities from entering the bearing interior, firmly locking the pre-filled lubricating grease, avoiding lubrication failure and component wear, and significantly extending the maintenance-free period. It has good radial and bidirectional axial load-bearing capacity, low friction design ensures smooth operation, moderate rotational speed performance meets the routine operation requirements of most small-sized equipment, and with its core advantages of simple structure, convenient installation, dust-proof durability, and high cost-effectiveness, it becomes the preferred support solution for general mechanical scenarios with clean environment requirements.
