6002-ZZ Ball Bearing

The 6002-ZZ Ball Bearing is a deep groove ball bearing engineered for compact equipment requiring fast rotational response, low friction, and efficient operation in high-speed applications.

Equipped with double metal shields (ZZ), this model supports lower rolling resistance compared to rubber-sealed bearings, making it a common choice for electromechanical systems operating continuously at elevated RPM. Its deep groove design contributes to smooth rotation, reduced vibration, and dependable operational stability even in compact equipment.

Manufactured from chrome steel and supplied factory pre-lubricated, the 6002-ZZ is widely used in small motors, industrial ventilation systems, and automated equipment.
