6801 2RS Deep Groove Ball Bearing 12×21×5 mm | ISO 18 Series – Extra Light | Double Rubber Sealed
This precision bearing incorporates a reliable deep groove design and full-contact rubber seals, making it suitable for applications where environmental sealing is as critical as performance. The 6801-2RS supports moderate radial loads and can accommodate light axial loads in both directions. Its slim profile, combined with effective sealing, makes it a preferred choice for small drives, medical devices, office automation equipment, and other applications exposed to dust or occasional moisture.

Engineered for a diverse range of compact and precision-focused applications requiring both protection and performance:
Lip-type rubber seals on both sides create a reliable barrier against dust, moisture, and grime. This contact sealing design significantly extends lubricant life and bearing service intervals, making it ideal for maintenance-sensitive or dirty environments.
Built to extra-light series dimensions (12×21×5 mm), this bearing offers a favorable balance of load capacity and compactness. It handles radial loads effectively and is suitable for applications where axial space is at a premium.
Manufactured to standard precision grades with consistent internal geometry, the 6801-2RS ensures low noise and vibration levels, contributing to the smooth and reliable operation of sensitive mechanical and electronic systems.
