684 2RS 4x9x4 Rubber Sealed Bearing
684 2RS sealed ball bearings, the bearings are made of chrome steel, the bearings are sealed with rubber seals to protect the bearings from dust or any possible contamination, this is a self-lubricating bearing (the bearing is already lubricated).
The miniature ball bearing 684 2RS is small enough to fit in confined spaces and on thin shafts. It can withstand very high speeds. Main dimensions according to DIN 625-1.
This metric size miniature ball bearing has a deep groove geometry. It is suitable for applications involving combined radial and axial loads and where high running accuracy at high rotational speeds is required. For example, 684 2RS are commonly used in motors, ATMs and card readers. The 684 2RS are also popular in the food and beverage industry.
More specifically, 684 2RS miniature bearings are widely used in industrial and scientific applications such as medical and industrial handpieces, flow meters, fuel controls, gyroscopes, synchronizers, servo systems, electric motors, cryocoolers, pulmonary assist devices, and more.
