The 6702-2RS is a high-precision, extra-light series bearing engineered for mechanical assemblies where radial space is extremely limited but environmental protection is mandatory. Outfitted with dual contact rubber seals (2RS), this bearing provides a resilient barrier against fine dust, moisture, and lubricant leakage. With a 15mm bore and a slender 4mm width, it is an essential component for high-performance bicycle hubs, robotic joint actuators, and compact medical rotary devices.
