F682 2rs Bearing Product Overview & Core Advantages
The F682 2RS is a miniature deep groove ball bearing designed for compact, high-precision applications. Engineered with a single row construction and integral rubber seals (2RS), this metric bearing excels in providing reliable radial load support while offering protection against contamination. Its small bore diameter of 2 mm and overall compact dimensions make it an ideal solution for applications where space is at a premium and consistent performance is critical. The bearing is pre-lubricated, ensuring immediate operation and contributing to its high reliability in demanding environments.
F682 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Significance |
|---|---|---|
| F682 | Bearing series and size designation | Identifies this specific miniature bearing series with a 2mm bore, 5mm OD, and 2.3mm width. |
| 2RS | Double-sided contact rubber seals | Provides excellent contamination protection from both sides, retaining lubricant and excluding moisture and debris. This contributes to the bearing's long service life and suitability for various environments. |
F682 2rs Bearing Structural Features & Performance Benefits
Compact & Robust Design: The single row deep groove raceway and chrome steel construction provide high radial load capacity relative to its miniature size. With a radial dynamic load rating of 32 lbf, it offers reliable performance in compact assemblies.
Enhanced Sealing & Protection: The Nitrile Rubber (NBR) seals (2RS) effectively shield the internal components from contaminants while retaining the lubricant. This design is crucial for maintaining performance in applications where dust or small particles are present.
Precision & Smooth Operation: Manufactured to ABEC1 tolerance class and featuring a stainless steel cage, the bearing ensures smooth rotation and consistent performance. The MC3 radial internal clearance (0.002mm to 0.013mm) is optimized for a wide range of operating conditions.
High-Speed Capability: With a limiting speed of 85,000 rpm, this bearing is suitable for high-speed miniature applications, supported by its balanced design and effective sealing.
