6906 2rs Bearing Product Overview & Core Advantages
The 6906 2RS is a single row deep groove ball bearing designed for reliable performance in demanding applications. As a metric sealed bearing, its primary advantage lies in its ability to handle significant radial loads while offering protection from contamination. The inclusion of contact seals (2RS) on both sides ensures the retention of lubricant and exclusion of pollutants, making it a robust and low-maintenance solution for a wide range of industrial machinery.
6906 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6906 | Basic Bearing Series & Size | Indicates a deep groove ball bearing with a 30mm bore, 47mm OD, and 9mm width. |
| 2RS | Double Contact Seals | Features NBR rubber seals on both sides, providing excellent protection against dust and moisture, and retaining lubricant for extended service life. |
6906 2rs Bearing Structural Features & Performance Benefits
Optimized for Radial Load Capacity: The single row deep groove raceway geometry is engineered to support high radial dynamic load ratings (1629 lbf) efficiently. This makes the bearing suitable for applications with significant radial forces.
Sealed for Longevity and Reliability: The contact seals (2RS) are a critical feature, shielding the chrome steel rings and balls from contaminants. This design significantly enhances bearing life in unclean environments and reduces the need for frequent re-lubrication.
Precision and Stability: Manufactured to ABEC-1 tolerance class with a standard C0 radial internal clearance (0.006mm to 0.020mm), this bearing offers consistent performance and running accuracy for general industrial use.
Durable Cage Construction: The stainless steel cage provides high strength and corrosion resistance, contributing to stable operation at the specified limiting speed of 17,000 rpm.
6906 2rs Bearing Typical Application Areas
The 6906 2RS is a versatile component found in numerous sectors due to its balanced performance and sealed design. Common applications include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
