Product Overview: The 689 Miniature Deep Groove Ball Bearing
The 689 bearing is a compact, high-precision component belonging to our 6800 Series of extra-thin section Deep Groove Ball Bearings. With its miniature dimensions of 9mm bore diameter, 17mm outer diameter, and 4mm thickness, this bearing is specifically engineered for applications where space is extremely limited but reliable rotational performance is essential. Its single-row deep groove geometry enables it to handle both radial and light axial loads in both directions, making it a versatile choice for a wide range of compact machinery and devices.
As a key part of our Miniature Deep Groove Ball Bearings collection, the 689 is manufactured from high-quality bearing steel to ensure durability and a long service life, even in high-speed operations. Its design minimizes rotational friction, contributing to greater energy efficiency and reduced heat generation. This makes it an ideal solution for intricate mechanical systems requiring smooth and quiet operation.
