SS 686 ZZ/2RS stainless steel deep groove ball bearings

A balanced material system and precision manufacturing; the raceway uses a variety of stainless steel materials to meet the balanced requirements of corrosion resistance and mechanical strength under different working conditions; the internal G10 grade high-precision stainless steel balls ensure smooth rotation characteristics with low friction and low noise, improving the operating quality of the micro transmission system; the small radial cross section and high space utilization make it suitable for miniaturized and integrated mechanical structures; the deep groove raceway design can effectively withstand radial loads and a certain bidirectional axial load; the metal dust cover (ZZ) provides basic dust protection, and the rubber seal ring (2RS) effectively prevents moisture and fine impurities from entering, maintaining the performance of the internal grease and the cleanliness of the bearing.

Choosing the SS686 bearing is primarily about its precise dimensional fit for miniature devices. Its slim 6x13x3.5 mm cross-section provides reliable rotational support in extremely compact machine layouts, making it an ideal solution for optimizing space utilization in miniature devices. Our manufacturing expertise ensures the inherent quality of our products. The bearings are machined from solid stainless steel bars supplied by specialized steel mills, rather than using tubular stock, resulting in a denser and more uniform material structure for the raceways. Our one-stop production model allows for rigorous quality control throughout the entire process, from raw materials to finished products. We offer high configuration flexibility. You can choose from a variety of materials, including AISI 420, 440, and 304, as well as different specifications of industrial or food-grade greases and NBR or FKM seals, depending on specific corrosion resistance requirements, operating temperatures, and lubrication conditions. Furthermore, we support non-standard machining, such as grooved outer rings or V-grooved inner rings, to meet special installation or sensing requirements.
