S682 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S682 | Basic bearing series designation, indicating a specific miniature bearing size with a 2mm bore. |
| 2RS | Signifies that the bearing is equipped with contact rubber seals (RS) on both sides (2). This provides superior protection against contaminants and retains lubricant effectively. |
S682 2rs Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of just 2mm (bore) x 5mm (OD) x 2.3mm (width) and a weight of only 0.15g, this bearing is ideal for ultra-compact assemblies.
- High-Speed Capability: The optimized design and stainless steel cage contribute to a high limiting speed of 76,500 rpm, suitable for demanding rotational applications.
- Effective Sealing: The 2RS rubber seals effectively shield the internal components from dust, moisture, and other contaminants, extending the bearing's service life and reducing maintenance needs.
- Corrosion Resistance: The use of stainless steel for the rings, balls, and cage ensures reliable performance in humid or mildly corrosive environments.
- Precision Internal Clearance: The MC3 radial internal clearance (0.002mm to 0.013mm) is suited for applications requiring precise running accuracy and minimal vibration.
