6308/VW514 Bearing Product Overview & Core Advantages
The 6308 is a single row deep groove ball bearing designed for optimal performance in general industrial applications. This metric bearing excels at handling primarily radial loads and offers reliable operation due to its robust construction. Its key advantages include a high limiting speed of 7,500 rpm, a substantial radial dynamic load rating of 9,150 N, and compliance with ABEC 1 | ISO P0 tolerance standards, ensuring consistent quality and interchangeability. Manufactured entirely from chrome steel, it provides excellent durability and is suitable for a wide operating temperature range.
6308/VW514 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 63 | Series designation indicating medium duty and specific dimensional series. |
| 08 | Bore diameter code, corresponding to a 40 mm bore. |
| Open (Seal Type) | No seals or shields, allowing for higher speeds and easier re-lubrication. |
| CN (Radial Clearance) | Standard normal radial internal clearance group, suitable for most common operating conditions. |
6308/VW514 Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and continuous ring construction provide high radial load capacity and can accommodate moderate axial loads in both directions.
- High-Speed Capability: The open design and chrome steel cage minimize friction and allow for a high limiting speed, making it suitable for demanding applications.
- Precision & Interchangeability: Manufactured to ABEC 1 | ISO P0 tolerance class, ensuring dimensional accuracy and reliable performance in a wide range of machinery.
- Material Integrity: All core components (rings, balls, cage) are made from high-grade chrome steel, offering excellent resistance to wear and fatigue, contributing to a long service life.
