W 6208 Bearing Product Overview & Core Advantages
The W 6208 is a metric single row deep groove ball bearing engineered for high performance in demanding applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance and is designed to primarily handle radial loads. Its open design allows for versatile lubrication options and facilitates high-speed operation. This bearing is characterized by its high precision (P0 tolerance class) and reliable operation within a wide temperature range, making it a robust and durable solution for various industrial settings.
W 6208 Bearing Model Code Explained, Specifications & Naming Convention
The model number W 6208 can be broken down as follows, with key specifications detailed in the table.
| W | Manufacturer's prefix/series identifier. |
| 62 | Series code, indicating a medium-duty deep groove design. |
| 08 | Bore diameter code, corresponding to a 40 mm bore. |
| (Implied "Open") | No seal/shield suffix, indicating an open bearing. |
The absence of specific suffixes for seals or special grease highlights its standard, open configuration, providing maximum flexibility for application-specific lubrication.
W 6208 Bearing Structural Features & Performance Benefits
The performance of the W 6208 is a direct result of its precise engineering and material selection.
- All-Stainless-Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and enabling use in harsh environments, from food processing to chemical exposure.
- Optimized Load Capacity: The deep groove raceway and single-row design are optimized to carry significant radial dynamic load ratings (5643 lbf) and radial static load ratings (3957 lbf).
- High-Speed Capability: The open structure and stainless steel cage contribute to a high limiting speed of 12,000 rpm, minimizing friction and heat generation.
- Standard Precision & Clearance: Manufactured to P0 tolerance class with CN group radial internal clearance, ensuring consistent performance, smooth operation, and easy interchangeability.
