The 6706-2RS is an ultra-slim, single-row deep groove ball bearing specifically designed for high-performance applications that demand both extreme spatial efficiency and superior environmental protection. Outfitted with dual contact rubber seals (2RS) made from high-grade Nitrile (NBR), this bearing prevents the ingress of dust, moisture, and fine particulates while locking in premium synthetic grease for the entire service life of the component. With its 30mm bore, 37mm outer diameter, and a minimal 4mm width, it serves as the essential choice for portable medical instruments, outdoor robotics, and precision sensors where reliability in contaminated environments is non-negotiable.
