In the ever - evolving landscape of industrial motion, the 608ZZ High - Speed Deep groove ball bearing stands as a pinnacle of engineering excellence within our diverse bearing portfolio. With dimensions of 8mm inner diameter, 22mm outer diameter, and 7mm width, it firmly positions itself as a notable member of our Small bearing series, while embodying the quintessential features that define Deep groove ball bearings as the cornerstone of countless mechanical systems.

Engineered for velocity, the 608ZZ is a testament to precision and performance. Its double - shielded (ZZ) structure, crafted from high - strength stainless steel through advanced stamping technology, forms a robust barrier against dust, debris, and contaminants. This design, certified to IP54 protection standards, ensures the integrity of internal components even in the most demanding environments. The precision - engineered symmetrical deep groove raceways, combined with the optimized contact angles, enable the bearing to operate with minimal friction, achieving an impressive rotational speed of up to 25,000 revolutions per minute. Capable of handling a radial load of 1.05kN and an axial load of 0.4kN, it offers reliable performance in high - speed, high - precision applications, making it an ideal choice for everything from the intricate drives of precision optical instruments to the rapid - spinning components of miniature drones.

Constructed from high - carbon chromium bearing steel of the same superior quality as our Stainless steel bearing range, the 608ZZ undergoes a meticulous manufacturing process. Through vacuum quenching, tempering, and deep cryogenic treatment, its surface hardness reaches HRC60 - 62, creating a dense and wear - resistant layer that provides excellent abrasion and corrosion resistance. As a classic Ball bearing, it features precision - grade G10 steel balls that roll with unparalleled smoothness within the deep groove raceways, ensuring efficient power transmission and extended service life. Whether subjected to continuous high - speed operation or intermittent heavy loads, the 608ZZ maintains its stability and reliability, reducing maintenance requirements and enhancing overall system efficiency.

For projects with unique specifications, our Non - standard bearing customization service offers tailored solutions. Our team of experienced engineers, leveraging state - of - the - art CAD/CAM design systems and extensive industry knowledge, can modify various aspects of the 608ZZ, from adjusting the seal type for enhanced chemical resistance to customizing the internal clearance for specific temperature conditions. In the realm of Water pump bearing applications, the 608ZZ has proven its mettle. When integrated into micro - water pump systems, it withstands the rigors of continuous operation and vibration, achieving a dynamic load coefficient (C) of 1.2kN. After 1500 hours of rigorous testing, the bearing clearance variation remains within ≤0.005mm, demonstrating stability comparable to our specialized Water pump bearings. This makes it an excellent choice for ensuring the long - term, stable, and efficient operation of water pump systems, whether in residential water filtration setups or compact industrial pumping units.

From the micro - scale operations of precision instruments to the heavy - duty requirements of industrial machinery, the 608ZZ High - Speed Deep Groove Ball Bearing, with its outstanding performance, seamlessly integrates with our comprehensive range of bearings. In synergy with our Stainless steel bearing, Ball bearing, Deep groove ball bearing, Non - standard bearing, Small bearing, and Water pump bearing products, we are committed to providing reliable, high - quality solutions that meet the diverse needs of every project, propelling industries forward with the power of precision engineering.
