686 ZZ Miniature Deep Groove Ball Bearing for Compact Drive Systems | 6×13×5 Mm

The 6801-2RS is a Compact and Sealed Deep Groove Ball Bearing designed for applications requiring reliable, maintenance-free operation in challenging environments. Featuring integrated double rubber seals (2RS) on both sides, this bearing provides excellent protection against dust, moisture, and fine contaminants. The effective sealing retains lubricant, minimizes friction, and ensures smooth, long-lasting performance. With its slender 12mm bore and narrow 5mm width, it is an ideal solution for space-constrained designs in small electric motors, gearboxes, and precision instruments.

The 685-ZZ is a Compact Double-Shielded Deep Groove Ball Bearing designed for reliable performance in small-scale mechanical applications. Featuring the standard deep groove raceway, this miniature bearing efficiently handles moderate radial loads and light axial loads in both directions. With a 5 mm bore, 11 mm outer diameter, and a square-type 5 mm width profile, it offers a robust yet space-efficient design. Equipped with double metal shields (ZZ) for contamination protection, it is well-suited for small electric motors, light-duty mechanisms, and precision devices requiring smooth operation with minimal maintenance.

The 686-ZZ is a High-Performance Miniature Deep Groove Ball Bearing developed for precision applications demanding reliable operation within a slim profile. Featuring dual metal shields (ZZ) on both sides, this bearing offers advanced protection against airborne particles and debris while ensuring smooth, low-torque rotation. With a 6 mm bore and a compact 5 mm width, it is engineered for small motors, compact fans, and electromechanical devices where space efficiency and contamination resistance are essential.

The 688-ZZ is a Reliable Miniature Deep Groove Ball Bearing designed for applications that require a balance of compact cross-section, contamination protection, and smooth operation. Equipped with double metal shields (ZZ), it offers effective two-side defense against dust and debris while maintaining low rotational torque. With an 8 mm bore and a slim 5 mm width, this bearing is particularly suited for small electric motors, compact fans, and precision mechanisms where radial space is limited and environmental protection is valued.

The 6806-2RS is a Double Rubber-Sealed Extra-Light Series Deep Groove Ball Bearing designed for applications where space constraints and contamination protection are critical. Equipped with two rubber contact seals (2RS) on both sides, it efficiently blocks dust, moisture, and debris while maintaining internal lubrication. Featuring a 30 mm bore and a slim 7 mm width, this bearing is ideal for compact assemblies, small precision instruments, and light-duty mechanical systems where reliable sealing and smooth operation are essential.

The 6804-2RS is a Double Rubber-Sealed Extra-Thin Deep Groove Ball Bearing developed for compact assemblies requiring reliable protection against contaminants. Fitted with two rubber contact seals (2RS) on both sides, it effectively blocks dust, moisture, and fine particles while retaining grease for extended service. With a 20 mm bore and a slim 7 mm width, this bearing is especially suitable for applications where radial space is limited and sealing performance cannot be compromised.

The 6803-2RS is a Double Rubber-Sealed, Extra-Thin Series Deep Groove Ball Bearing engineered for applications where minimal axial space and reliable contamination protection are paramount. Featuring two integrated rubber contact seals (2RS), it provides an effective barrier against dust, moisture, and fine particulates while securing internal lubrication. With a compact 17 mm bore and an exceptionally slim 5 mm width, this bearing is the ideal choice for highly space-constrained mechanisms requiring dependable sealed performance.

The 6802-ZZ is a Double Metal-Shielded, Extra-Thin Series Deep Groove Ball Bearing designed for applications requiring high-speed capability and basic contamination protection in a minimal axial space. Equipped with two pressed steel shields (ZZ), it effectively guards against larger dust particles and debris while maintaining low internal friction. With a 15 mm bore and an ultra-slim 5 mm width, this bearing is an optimal choice for precision mechanisms where space is limited and lower torque is preferred over full sealing.
