698ZZ Water Pump Bearing 8×19×6mm

In the precision - oriented realm of industrial transmission, each bearing type serves as the cornerstone for ensuring equipment operates with peak efficiency. Our company, deeply rooted in the bearing manufacturing industry, leverages cutting - edge technological R&D and stringent quality control measures. The comprehensive product portfolio, encompassing Stainless steel bearing, Ball bearing, Deep groove ball bearing, Non - standard bearing, Small bearing, and Water pump bearing, is designed to deliver reliable transmission solutions to diverse industries worldwide.​

 

The 698ZZ Water pump bearing, with dimensions of 8×19×6mm, stands as an exemplary model among Water pump bearings. Despite its classification as a Small bearing, its compact 8×19×6mm size belies its formidable performance capabilities. The double dust cover (ZZ) shielding structure, fabricated from high - strength stamped steel, is meticulously joined to the bearing's inner and outer rings through precision welding techniques. With an IP54 protection rating, it acts as an impregnable barrier, effectively repelling dust, sand, and other contaminants. Whether deployed in sewage pumps with high particulate content or in the humid and dusty environments of industrial pumping operations, it safeguards the integrity of internal precision components, significantly reducing the risk of equipment failure and minimizing maintenance costs associated with impurity - induced wear.​

 

Crafted from high - carbon chromium bearing steel of the same premium quality as our Stainless steel bearings, the 698ZZ undergoes a series of meticulous processes, including vacuum quenching, tempering, and deep cryogenic treatment. This results in a surface hardness of HRC60 - 62, forming a dense wear - resistant layer that confers exceptional abrasion and corrosion resistance. As a distinguished member of the Ball bearing family, it is equipped with precision - grade G10 steel balls and features the classic symmetrical Deep groove raceway design characteristic of Deep groove ball bearings. Through extensive mechanical testing and advanced simulation optimization, it has been proven capable of stably supporting a radial load of 1.2kN and an axial load of 0.45kN. With a friction coefficient as low as 0.006, the bearing operates with remarkable efficiency. Even at high rotational speeds of 8000r/min, it maintains a vibration value ≤8m/s² and a noise level ≤43dB, ensuring stable and efficient power transmission for the high - speed rotation of water pump impellers. This not only enhances the operational efficiency of water pumps but also extends their service life.​

 

For projects with unique specification requirements, our Non - standard bearing customization service offers comprehensive support. Staffed by a team of experienced professional engineers and leveraging state - of - the - art CAD/CAM design systems, we provide personalized solutions. From optimizing material properties and innovating sealing structures to precisely controlling tolerance grades, we can meet a wide range of demands, including special size requirements and the use of specialized materials for transporting highly corrosive liquids.​

 

From the reliable water supply of household small water pumps to the high - volume fluid transportation of industrial large - scale pumps, the 698ZZ water pump bearing, with its exceptional performance, collaborates seamlessly with our full range of core products. Together, they form a solid foundation for the stable operation of water pump equipment, propelling industries towards new heights of efficiency and stability in the field of fluid transportation.
