6808 Bearing Product Overview & Core Advantages
The 6808 metric ball bearing is a high-performance single row deep groove ball bearing engineered for reliable operation in a wide range of industrial applications. Its fundamental design is optimized to primarily support radial loads, making it a versatile and essential component. Manufactured to ABEC-1 precision tolerances, this bearing offers a robust balance of performance, durability, and cost-effectiveness. Its compact cross-section, with a 7 mm width, allows for space-saving designs without compromising on load capacity or operational integrity.
6808 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Significance |
|---|---|---|
| Basic Designation | 6808 | Denotes a metric, single row deep groove ball bearing with a 40 mm bore and 52 mm outside diameter. |
| Seal Type | Open | No integral seals or shields. Requires external sealing for contaminated environments, allowing for higher limiting speeds and custom lubrication. |
| Tolerance Class | ABEC-1 | Specifies standard precision levels for dimensional accuracy and running performance. |
| Internal Clearance | C0 | Indicates a normal radial internal clearance range of 0.006mm to 0.020mm, suitable for most general operating conditions. |
6808 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The single row deep groove construction and high-quality chrome steel rings and balls provide a dynamic load rating of 1109 lbf and a static load rating of 940 lbf, ensuring reliable performance under significant radial loads.
- High-Speed Capability: The lightweight, durable stainless steel cage effectively retains the balls, contributing to stable operation at high rotational speeds, with a limiting speed of 14,000 rpm.
- Precision Engineering: Adherence to ABEC-1 tolerance class ensures consistent dimensional accuracy and smooth, low-vibration running, which is critical for the longevity of the entire assembly.
- Material Integrity: Components made from chrome steel offer excellent hardness and wear resistance, while the stainless steel cage provides superior corrosion resistance, enhancing the bearing's operational lifespan.
- Compliance & Safety: The bearing is ROHS and REACH compliant, meeting stringent international standards for environmental safety and material restrictions.
