62800-2Z

The 62800-2Z is a 628 series small double-sided dust-proof sealed deep groove ball bearing (with an inner diameter of 10mm specification). Its core function is to provide low friction, high stability, and long life rotational support for small precision equipment with limited space and clear requirements for cleanliness protection. With its compact structure size of 10mm inner diameter, 19mm outer diameter, and 5mm width, it inherits the basic advantage of deep groove ball bearings that can simultaneously withstand radial loads and a small amount of bidirectional axial loads. Through the dual protective design of the 2Z type double-sided stamped steel dust cover, it can effectively prevent dust and impurities from entering the bearing interior, avoid lubricant leakage, significantly reduce the risk of wear caused by contaminants, and extend the maintenance-free period and overall service life of the bearing. It is made of high-carbon chromium bearing steel (GCr15) for the rings and rolling elements, and after professional quenching and heat treatment, its hardness reaches HRC60-64, possessing excellent wear resistance, fatigue resistance, and dimensional stability. Combined with lightweight stamped steel cages and high-performance lithium-based lubricating grease, it has a low friction coefficient and low operating noise, and can meet the high-speed operation requirements under medium to low loads without complex maintenance, ensuring the smooth operation of the equipment. This bearing is precisely matched with "compact size + double-sided dust-proof + precise performance", and is widely used in small motors, precision instruments and meters, automated micro-components, power tools, office equipment, handheld portable devices, laboratory small equipment, light industrial machinery, and medical devices (portable models), providing efficient and long-lasting support and protection for various rotating mechanisms with requirements for installation space, cleanliness, and operational stability.
