628/6-2Z

The 628/6-2Z 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 multi-scenario applications in industrial production and civilian settings where there are clear requirements for cleanliness and low maintenance. This bearing maintains a compact size of 6mm inner diameter, 13mm outer diameter and 5mm width, perfectly fitting the narrow installation space of miniature motors, small transmission mechanisms and other equipment; the rings 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 core upgraded double-sided metal dust-proof cover (with the 2Z code) design can effectively prevent dust, fibers, debris and other impurities from entering the bearing interior, firmly locking in pre-filled lubricating grease and avoiding lubrication failure and rolling element wear, significantly extending the maintenance-free period and service life. It has good radial and bidirectional axial load-bearing capacity, low friction design ensuring smooth operation, excellent vibration and noise control, moderate rotational speed performance meeting 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 basic requirements for working environment cleanliness.
