Product Overview: The 687 Miniature Deep Groove Ball Bearing
The 687 bearing is a compact, high-precision component belonging to our 6800 Series of thin-section bearings, also known as Miniature Deep Groove Ball Bearings. With its precise dimensions of a 7mm bore diameter, 14mm outer diameter, and 5mm thickness, this bearing is engineered for applications where space is extremely limited but high rotational performance is essential. Its single-row deep groove geometry allows it to handle both radial and moderate axial loads in both directions, making it a versatile choice for a wide range of compact machinery and devices.
As a premier supplier of industrial components, we ensure our 687 bearings are manufactured from high-quality bearing steel, offering low friction, minimal noise, and a long service life. This bearing is a fundamental part of many small mechanical systems, from hobbyist electronics to sophisticated medical equipment.
