The 687-ZZ is a highly specialized thin-section miniature bearing engineered for demanding electromechanical systems where radial space is strictly limited but high rotational accuracy is mandatory. Equipped with dual non-contact metal shields (ZZ), this compact component effectively repels particulate contamination while retaining its internal lubrication. Featuring a 7mm bore, a 14mm outer diameter, and a 5mm width, it delivers exceptional operational stability for advanced robotics, high-speed UAV motors, and automated industrial tooling.
