The 682-ZZ is a precision-engineered, double-shielded miniature deep groove ball bearing designed for high-velocity applications where minimal friction is a critical requirement. With its compact 2 mm bore and 5 mm outer diameter, this bearing provides exceptional rotational stability in micro-scale assemblies. Equipped with two non-contact metal shields (ZZ), it effectively prevents the ingress of larger debris and retains factory-applied grease without the frictional drag associated with contact seals, making it ideal for high-RPM micro-motors.
