Product Overview and Core Advantages
The 6208-2Z/C3 is a single row deep groove ball bearing designed for exceptional reliability in demanding industrial applications. This shielded bearing excels at handling significant radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a robust construction for high rigidity, a generous C3 radial internal clearance suitable for applications with thermal expansion, and integrated shields that protect against contamination, contributing to a long service life and reduced maintenance needs.
6208-2Z/C3VT127 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6208 | Standard bore diameter of 40 mm, outside diameter of 80 mm, and width of 18 mm. | Defines the core bearing dimensions for interchangeability and fit. |
| 2Z | Bearing is equipped with non-contact shields on both sides. | Offers effective protection against solid contaminants while allowing for high-speed operation. |
| C3 | Radial internal clearance greater than Normal (CN) group. | Accommodates thermal expansion in the shaft or housing, preventing preload and ensuring stable operation in varying temperature conditions. |
Structural Features and Performance Benefits
- Robust Single Row Design: Manufactured from high-grade chrome steel for rings, balls, and cage, this bearing provides a balanced combination of strength and durability, ensuring consistent performance under radial dynamic loads up to 6542 lbf.
- Optimized for Contaminated Environments: The non-contact 2Z shields act as a physical barrier against dust and debris, significantly enhancing bearing life in harsh conditions without the torque drag associated with contact seals.
- Thermal Stability with C3 Clearance: The C3 radial internal clearance is a critical feature for applications where operational heat causes expansion of adjacent components, preventing binding and maintaining smooth rotation.
- High-Speed Capability: With a limiting speed of 8,300 rpm, this bearing is suitable for a wide range of high-velocity applications. The pressed steel cage and optimized geometry contribute to its stable high-speed performance.
6208-2Z/C3VT127 Bearing Typical Application Areas
This versatile bearing is ideally suited for a broad spectrum of industrial machinery, including:
- Electric Motors and Generators
- Industrial Gearboxes and Power Transmission Systems
- Agricultural Machinery
