6308 MC/P52 Bearing Product Overview & Core Advantages
The 6308 is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. As a metric precision bearing manufactured to ABEC 5 | ISO P5 tolerance standards, it delivers high running accuracy and rotational stability. Its primary advantage lies in its ability to efficiently accommodate radial loads, making it a versatile and reliable choice for a wide range of industrial machinery. The open design allows for versatile lubrication options, while the robust construction ensures long service life and high operational reliability.
6308 MC/P52 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 63 | Series Code | Indicates a medium-duty, single row deep groove ball bearing. |
| 08 | Bore Diameter Code | Specifies a standard bore diameter of 40 mm (bore = 08 * 5 mm). |
| [No Suffix] | Standard Design | Denotes an open (unsealed) bearing with a CN radial internal clearance and no pre-lubrication. |
6308 MC/P52 Bearing Structural Features & Performance Benefits
- High-Precision Design: Manufactured to ABEC 5 | ISO P5 tolerance class, this bearing ensures low vibration, minimal noise, and superior rotational accuracy, which is critical for high-speed applications.
- Robust Load Capacity: With a dynamic load rating of 915 lbf and a static load rating of 5395 lbf, it is designed to handle significant radial loads, providing reliable performance under strenuous conditions.
- Optimized for High-Speed Operation: The combination of a machined metal cage and the open structure contributes to a high limiting speed of 7,500 rpm, allowing for smooth operation at elevated rotational velocities.
- Superior Material Construction: Both the rings and balls are made from high-grade chrome steel, offering excellent hardness, wear resistance, and durability. The machined metal cage provides high strength and dimensional stability.
- Versatile Application Range: The standard CN radial internal clearance and the absence of seals or lubricant make it suitable for applications where specific lubrication systems are used or where operating temperatures range from -30°C to 120°C.
