S679zz Bearing Product Overview & Core Advantages
The S679zz is a metric miniature ball bearing designed for applications requiring compact dimensions and reliable performance. As a single row deep groove ball bearing, it is primarily engineered to support radial loads efficiently. Constructed entirely from stainless steel, it offers excellent corrosion resistance. The integrated shielded (ZZ) design protects against contaminant ingress, enhancing operational longevity. Its compact size (9mm bore, 14mm OD, 4.5mm width) and ABEC1 precision make it an ideal choice for high-speed, space-constrained applications demanding consistent accuracy and durability.

| Code Segment | Technical Meaning |
|---|---|
| S | Stainless Steel construction for enhanced corrosion resistance. |
| 679 | Bore size code indicating a 9mm bore diameter. |
| zz | Specifies shielded seals on both sides for protection against dust and debris. |
S679zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a width of just 4.5mm and a weight of 1.98g, this bearing is engineered for applications where space and weight are critical constraints.
- Robust Load Capacity: Features a radial dynamic load rating of 158 lbf and a radial static load rating of 76 lbf, providing reliable performance under significant stress.
- High-Speed Capability: The optimized design, including 12 precision balls and a stainless steel cage, enables a high limiting speed of 32,400 rpm.
- Enhanced Service Life: The stainless steel shields (ZZ) effectively retain lubrication and exclude contaminants, reducing maintenance needs and extending bearing life.
- Stable Operation: Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance (0.002mm to 0.013mm), ensuring smooth, low-vibration, and precise rotation.
S679zz Bearing Typical Application Areas
This bearing is widely used in precision instruments and compact machinery, including:
- Small Electric Motors and DC Micromotors
- Precision Medical Devices and Dental Handpieces
- Office Automation Equipment (e.g., printers, scanners)
- Robotics and Small Gearboxes
