The 671-2RS is a double-sealed miniature deep groove ball bearing engineered for applications demanding reliable protection in ultra-compact spaces. With its 1mm bore and 3mm outer diameter, this micro-bearing incorporates rubber contact seals to provide permanent lubrication retention and effective barrier against fine contaminants. The deep raceway geometry ensures smooth handling of light radial loads while the integrated sealing solution makes it particularly suitable for medical handpieces, precision instruments, and small electric motors where maintenance access is limited and operational reliability is paramount.
