8x16x5mm High-Speed Miniature Ball Bearing 688ZZ

The 688ZZ, a Small bearing and a prime example of our Deep groove ball bearing lineup, with precise dimensions of 8x16x5mm, exemplifies our unwavering commitment to precision engineering. As a standout in our diverse range of Small bearings, it adheres to the same rigorous quality standards as our Stainless steel bearings and other Ball bearings. This ensures exceptional durability and reliability, even in the most demanding operational environments—from dusty industrial workshops to high-humidity manufacturing facilities.​

 

Deep groove ball bearings, including the 688ZZ, represent the most widely used category of rolling bearings worldwide. Their minimal frictional resistance and high-speed capabilities make them indispensable across countless industries. While primarily designed to handle radial loads, they also excel in managing combined radial and axial loads—much like our specialized Water pump bearings, which must perform reliably under varying stress conditions in wet environments. This versatility positions Deep groove ball bearings as the ideal choice for applications ranging from small electric motors in household appliances to precision instruments in medical equipment.​

 

The 688ZZ Deep groove Ball bearing features a robust construction comprising an outer ring, inner ring, precision steel balls, a durable cage, dust cover, and high-performance grease. The ZZ seal provides exceptional protection against contaminants, ensuring long-term lubrication and minimal maintenance. As a member of the 68 series, this thin-walled bearing is optimized for light-load scenarios. Its compact, lightweight design enables seamless integration into a wide array of equipment, including small-power motors, electric tools, toys, household appliances, gearboxes, and general machine tools—where space efficiency and reliable performance are critical.​

 

Our commitment to innovation extends beyond standard products. We specialize in Non-standard bearing customization, offering tailored solutions to meet unique project requirements. Whether you need an outer ring with grooves for enhanced heat dissipation, a widened inner ring for specialized shaft designs, or precise adjustments to inner/outer diameters, our engineering team collaborates closely with you at every stage. Despite the complexities of non-standard production, we prioritize clear communication to ensure each Non-standard bearing meets your exact specifications—from material selection to dimensional tolerances.​

 

As a trusted motor industrial bearing, the 688ZZ delivers consistent reliability. We provide C3 variant samples of the 688 bearing and support both small-scale prototyping and large-volume production runs. Whether you require standard Stainless steel bearings for corrosion-resistant applications, high-performance Deep groove ball bearings for precision machinery, or fully customized Non-standard bearing solutions, our comprehensive portfolio ensures we meet all your bearing needs with unmatched quality and technical expertise.
