6204-2Z/C3 GJN Bearing Product Overview & Core Advantages
The 6204-2Z/C3 GJN is a single row deep groove ball bearing designed for robust performance in demanding applications. This shielded bearing excels at handling radial loads and offers enhanced operational reliability. Its key advantages include a generous C3 radial internal clearance for thermal expansion management in high-temperature environments, and non-contact shields (2Z) that protect against contamination while minimizing friction. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent precision and is an ideal ready-to-install component for a wide range of industrial machinery.
6204-2Z/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6204 | Standard bearing series designation with 20mm bore. | Defines core bearing dimensions and geometry. |
| -2Z | Bearing is equipped with non-contact steel shields on both sides. | Provides effective contamination protection without significant speed penalty. |
| /C3 | Specifies a radial internal clearance greater than Normal (CN). | Accommodates thermal expansion, ideal for applications with elevated operating temperatures. |
| GJN | Indicates a light preload or specific internal geometry for higher rigidity. | Enhances running accuracy and system stiffness. |
6204-2Z/C3 GJN Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry (GJN): The specific internal design contributes to superior running accuracy and reduced vibration, making it suitable for precision applications.
- Robust Load Capacity: With a dynamic load rating of 2878 lbf and a static load rating of 1495 lbf, this bearing reliably handles significant radial loads.
- High-Speed Capability: The combination of a chrome steel cage and optimized internal design supports a limiting speed of 15,000 rpm.
- Shielded & Maintenance-Free: The 2Z shields retain the factory-fresh internal environment, preventing ingress of contaminants and offering a long service life without re-lubrication.
- Thermal Stability: The C3 clearance ensures stable performance and prevents seizure in applications where operational heat causes expansion of the inner ring.
6204-2Z/C3 GJN Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
