6308-2Z Bearing Product Overview & Core Advantages
The 6308-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered to primarily handle radial loads, it also accommodates moderate axial loads in both directions. Its key advantages include high-speed capability, reliable operation due to its shielded design, and consistent performance backed by P6 tolerance class precision. This bearing offers a compact and robust solution for applications requiring high reliability and long service life with minimal maintenance.
6308-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6308 | Standard series designation indicating a medium-duty, single row deep groove ball bearing with a 40mm bore, 90mm OD, and 23mm width. |
| 2Z | Signifies non-contact shields on both sides. This provides effective protection against contamination while allowing for high limiting speeds and minimal friction. |
6308-2Z Bearing Structural Features & Performance Benefits
- High-Speed Performance: The combination of a stainless steel cage and optimized grease lubrication enables a high limiting speed of 8,500 rpm, making it suitable for demanding rotational applications.
- Robust Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 9,509 lbf and a static load rating of 5,395 lbf, ensuring durability under significant radial stresses.
- Precision & Reliability: Built to P6 tolerance class with a standard CN radial internal clearance, it guarantees precise running accuracy and consistent performance, reducing vibration and noise.
- Low Maintenance & Contamination Protection: The 2Z shields effectively seal the bearing, retaining lubricant and excluding contaminants. The pre-applied grease provides reliable lubrication across a wide temperature range of -30°C to 120°C.
