The 6703-2RS is a high-performance, extra-light series ball bearing designed for mechanical assemblies that demand a balance between compact dimensions and superior protection. Equipped with dual-lip synthetic rubber seals (2RS), this model excels in shielding the internal raceways against moisture, grit, and lubricant leakage. Its thin-wall profile, featuring a 17mm bore and a 23mm outer diameter, makes it an essential component for outdoor robotics, bicycle hubs, and industrial sensors operating in challenging environments.
