S682zz Bearing Product Overview & Core Advantages
The S682zz is a miniature deep groove ball bearing designed for applications demanding compact size and reliable performance. As a metric shielded single row bearing, it excels in handling primarily radial loads with high efficiency. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include a compact design for space-constrained assemblies, a high limiting speed of 76,500 rpm for dynamic applications, and the inclusion of integrated shields (zz) to protect against contamination, making it a robust and durable choice for precision instruments and small machinery.
S682zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| S | Stainless Steel | Provides excellent corrosion resistance, suitable for harsh environments. |
| 68 | Series Designation (Extra Small & Thin Section) | Indicates a very compact bearing design. |
| 2 | Bore Diameter Code (2 mm) | Specifies the precise internal diameter. |
| zz | Shielded on Both Sides | Offers effective protection against dust and debris, retaining lubricant and extending service life. |
S682zz Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for high-capacity radial load support, ensuring smooth rotation and low running torque.
- Full Complement Stainless Steel Construction: All components, including rings, balls, and cage, are made from stainless steel, providing uniform thermal expansion and superior corrosion resistance.
- High-Speed Capability: The lightweight stainless steel cage and optimized internal geometry contribute to a very high limiting speed of 76,500 rpm, making it suitable for high-speed applications.
- Shielded Protection: The zz shields are non-contact, minimizing friction while effectively sealing the bearing against contaminants, enhancing reliability and reducing maintenance needs.
- Precision ABEC1 Class: Manufactured to ABEC1 precision tolerances, ensuring consistent performance, low noise, and vibration for smooth operation.
