6708 2rs Bearing Product Overview & Core Advantages
The 6708 2RS is a metric single row deep groove ball bearing designed for reliable performance in demanding applications. Its core advantage lies in its sealed design (2RS), which provides robust protection against contamination, making it suitable for environments where cleanliness is critical. Engineered with precision ABEC-1 tolerances, this bearing offers consistent operation and is capable of handling significant radial loads. Its compact cross-section, with a 6 mm width, allows for space-saving designs without compromising on load capacity or durability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6708 | Basic bearing series, indicating a metric, single row deep groove design with a 40 mm bore and 50 mm outside diameter. |
| 2RS | Contact rubber seals on both sides. This provides superior sealing effectiveness compared to non-contact shields, retaining lubricant and excluding contaminants. |
6708 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing: The dual contact rubber seals (2RS) effectively prevent the ingress of moisture, dust, and other contaminants, significantly extending bearing service life and reducing maintenance needs.
- High-Quality Materials: Constructed from chrome steel rings and balls with a stainless steel cage, this bearing offers excellent resistance to wear and corrosion, ensuring long-term reliability.
- Precision Performance: Manufactured to ABEC-1 tolerance class with a C0 radial internal clearance, it delivers smooth and quiet operation, which is essential for applications requiring consistent performance.
- Optimized Load Capacity: With a dynamic load rating of 565 lbf and a static load rating of 502 lbf, it is well-suited for applications with substantial radial forces.
6708 2rs Bearing Typical Application Areas
This sealed deep groove ball bearing is ideal for a wide range of applications across various industries, including:
- Electric Motors and Generators
- Small Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Conveyor System Idlers
- Medical and Dental Equipment
- Food Processing Machinery (where seals prevent contamination)
- Office Automation Equipment
