F679 2rs Bearing Product Overview & Core Advantages
The F679 2RS is a metric miniature ball bearing designed for compact applications requiring reliable performance. This single row deep groove ball bearing features integral rubber seals (2RS) on both sides, providing excellent protection against contamination. Its primary advantages include a compact design with a 9mm bore, capable of handling radial loads efficiently, and sealed construction for long-term operation in various environments. It is an ideal choice for applications demanding high reliability and minimal maintenance in confined spaces.
F679 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| F679 | Basic bearing designation, indicating a specific series of miniature deep groove ball bearings. |
| 2RS | Contact Nitrile Rubber Seals on both sides. This provides superior protection against dust and moisture ingress, preserving lubrication and extending bearing service life. |
F679 2rs Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from Chrome Steel rings and balls with a Stainless Steel cage, ensuring durability and corrosion resistance.
- Effective Sealing: The double-sided rubber seals (2RS) effectively retain lubricant and exclude contaminants, making the bearing suitable for environments where dirt or moisture is present.
- Precision & Smooth Operation: Built to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring consistent and smooth running performance.
- High-Speed Capability: The optimized design and stainless steel cage contribute to a high limiting speed of 36,000 rpm, suitable for demanding miniature applications.
- Flanged Design: The integrated flange (15.5mm outer diameter) simplifies mounting and positioning, enhancing axial location stability in housings.
