6310-2Z/GFF/R806 Bearing Product Overview & Core Advantages
The 6310-2Z/GFF/R806 is a high-performance single row deep groove ball bearing engineered for exceptional reliability in demanding applications. This precision bearing features integral shielded protection and a specialized pre-lubrication, making it an ideal solution for applications requiring robust radial load capacity and long-term, maintenance-free operation. Its compact design and high-quality chrome steel construction ensure consistent performance and extended service life.
6310-2Z/GFF/R806 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6310 | Standard bearing series designation, indicating a metric single row deep groove ball bearing with a 50mm bore, 110mm OD, and 27mm width. |
| 2Z | Signifies bearings with shields on both sides. This provides effective protection against contamination while allowing for higher rotational speeds compared to contact seals. |
| GFF | Indicates the bearing is pre-lubricated with a specific, high-performance grease. This ensures optimal performance from the first rotation and contributes to the bearing's maintenance-free characteristics. |
| R806 | Specifies the exact type of lubricating grease used, which is formulated to operate effectively within the specified temperature range of -30°C to 120°C. |
6310-2Z/GFF/R806 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The single row deep groove raceway geometry is optimized to support high radial dynamic load ratings (13,938 lbf), making it suitable for applications with significant radial forces.
- High-Speed Capability: The combination of shielded construction and a high-grade chrome steel cage allows for a high limiting speed of 6,000 rpm, enabling efficient operation in various machinery.
- Precision & Stability: Manufactured to ABEC 1 | ISO P0 tolerance class with a CN radial internal clearance, this bearing offers reliable running accuracy and smooth operation, reducing vibration and noise.
- Durability & Longevity: Constructed entirely from chrome steel for rings, balls, and cage, the bearing provides excellent resistance to wear and fatigue, ensuring a long operational lifespan.
- Maintenance-Free Operation: The 2Z shields and factory-applied GFF/R806 grease create a sealed, lubricated-for-life system, eliminating the need for re-lubrication and reducing total cost of ownership.
