6908 2rs Bearing Product Overview & Core Advantages
The 6908 2RS is a single row deep groove ball bearing designed for reliable performance in demanding applications. This metric bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its sealed construction (2RS) provides robust protection against contaminants, making it an ideal choice for applications requiring long service life and minimal maintenance. With its precise ABEC-1 tolerance class and balanced design, it delivers smooth operation and consistent performance.

| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 6908 | Basic bearing designation indicating a deep groove ball bearing with a 40mm bore, 62mm OD, and 12mm width. | Standardized bearing dimensions for easy interchangeability and sourcing. |
| 2RS | Double rubber contact seals on both sides. | Superior contamination exclusion, retaining lubricant for extended service intervals. |
6908 2rs Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway geometry is engineered to efficiently carry radial loads (Dynamic: 3082 lbf, Static: 2232 lbf) and accommodate axial loads from either direction, providing versatile load-handling capability.
- Robust Sealing & Protection: The dual rubber contact seals (2RS) effectively shield the internal components from dust, moisture, and other contaminants, significantly enhancing bearing life in harsh environments.
- Precision & Smooth Operation: Manufactured to ABEC-1 precision class with a controlled radial internal clearance (C0), this bearing ensures low vibration, quiet running, and consistent performance.
- Durable Material Construction: Components made from chrome steel (rings and balls) and a stainless steel cage offer excellent resistance to wear and corrosion, contributing to overall reliability.
6908 2rs Bearing Typical Application Areas
- Electric Motors and Small Gearboxes
- Industrial Pumps and Fans
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, idlers)
