6204-2Z/C4 Bearing Product Overview & Core Advantages
The 6204-2Z/C4 is a metric single row deep groove ball bearing engineered for high-performance applications requiring reliable radial load capacity. This shielded bearing features a C4 radial internal clearance, making it exceptionally suitable for applications with thermal expansion or where interference fits are used. Its ABEC 1 precision class ensures consistent operation, while the integral steel shields protect against contamination, offering a robust solution for industrial machinery.
6204-2Z/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6204 | Basic bearing series designation, indicating a medium-duty, single row deep groove ball bearing with a 20mm bore. |
| 2Z | Signifies contact-type steel shields on both sides. This provides effective protection against solid contaminants while allowing for higher limiting speeds compared to sealed types. |
| C4 | Indicates a greater than normal radial internal clearance. This is critical for applications involving significant temperature gradients or heavy press fits to prevent operational issues. |
6204-2Z/C4 Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove raceway geometry is optimized to support high radial loads (dynamic: 2878 lbf / static: 1495 lbf) and moderate axial loads in both directions, providing stable and rigid support for shafts.
- Optimized for Demanding Environments: The C4 clearance accommodates thermal expansion and interference fits, preventing excessive preload and potential bearing seizure, thereby enhancing operational reliability.
- Contamination Protection: The 2Z steel shields effectively retain the factory-applied lubrication and exclude larger particulate contaminants, contributing to a longer service life in dusty or dirty conditions.
- Precision Performance: Manufactured to ABEC 1 (ISO P0) tolerance class, this bearing ensures smooth and quiet running, minimizing vibration for consistent performance in general industrial applications.
6204-2Z/C4 Bearing Typical Application Areas
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Conveyors
- Agricultural Machinery
