Product Overview: The 688 Miniature Deep Groove Ball Bearing
The 688 bearing is a compact, high-precision component from our 6800 Series of extra-thin section bearings. As a type of Miniature Deep Groove Ball Bearing, it is engineered for applications where space is extremely limited but high rotational speed and reliability are essential. With principal dimensions of an 8mm bore diameter, 16mm outer diameter, and 5mm thickness, this bearing provides a robust solution for compact mechanical designs.
As a leading supplier of industrial components, we ensure our 688 bearings are manufactured to the highest standards. Their deep raceway grooves enable them to support both radial and moderate axial loads in both directions, making them incredibly versatile. This bearing is a fundamental component in a wide array of small-scale machinery and electronics, offering smooth, low-friction performance.
