S679 Bearing Product Overview & Core Advantages
The S679 is a metric single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This bearing is engineered to handle primarily radial loads and is characterized by its compact design with a minimal cross-section, making it ideal for space-constrained assemblies. Its ABEC1 precision class ensures consistent operation, suitable for various industrial and precision instruments.
S679 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S679 | Standard model number for a specific series of miniature deep groove ball bearings. |
| Open (Seal Type) | The bearing is unsealed, allowing for custom lubrication schemes but requiring a clean operating environment. |
| MC3 (Clearance) | Specifies a radial internal clearance group of 0.002mm to 0.013mm, suitable for most general applications. |
S679 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of 9mm (bore) x 14mm (OD) x 3mm (width) and a weight of just 1.35g, it is perfect for miniaturized and weight-sensitive applications.
- High-Speed Capability: The limiting speed of 32,400 rpm is supported by a stainless steel cage and optimized internal geometry, enabling reliable high-speed operation.
- Stainless Steel Construction: All components (rings, balls, cage) are made of stainless steel, providing superior corrosion resistance and durability in harsh environments.
- Precision Performance: Manufactured to ABEC1 tolerance class with controlled radial internal clearance, ensuring smooth and precise rotation with minimal vibration.
- Load Handling: Features a radial dynamic load rating of 158 lbf and a static load rating of 76 lbf, providing reliable support for radial loads in compact spaces.
