6004-2Z/C3 GJN Bearing Product Overview & Core Advantages
The 6004-2Z/C3 GJN is a single row deep groove ball bearing engineered for high-performance industrial applications. This shielded bearing features a C3 radial internal clearance, making it exceptionally suitable for applications with thermal expansion or where interference fits are used. Its design excels at handling high radial loads while accommodating moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable precision and operational consistency. The inclusion of integral shields ensures contaminant protection and preserves lubrication integrity, offering a robust solution for demanding environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6004 | Basic bearing series, indicating a metric deep groove ball bearing with a 20mm bore, 42mm OD, and 12mm width. |
| 2Z | Bearing is equipped with non-contact steel shields on both sides. This provides effective protection against contamination while allowing for high-speed operation. |
| C3 | Specifies a greater than normal radial internal clearance. This is critical for applications subject to thermal expansion or heavy interference fits, preventing operational issues due to clearance reduction. |
| GJN | Indicates the bearing is pre-lubricated with a specific, high-quality polyurea grease. This grease offers excellent performance across the specified temperature range and contributes to long service life. |
6004-2Z/C3 GJN Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway and high-grade chrome steel construction provide a high dynamic load rating of 2113 lbf, ensuring reliable performance under significant radial stresses.
- Enhanced Operational Stability: The C3 clearance is a key feature that accommodates dimensional changes from heat or press-fits, maintaining smooth operation and preventing seizure in challenging conditions.
- Contamination Resistance and Longevity: The 2Z shields effectively seal the bearing from dust and debris without the high friction of contact seals, supporting a limiting speed of 17,000 rpm. Combined with the GJN polyurea grease, this creates a long-lasting, low-maintenance bearing solution.
- Precision Engineering: Conformance to ABEC 1 precision class guarantees consistent running accuracy and low vibration, which is essential for the smooth operation of motors and precision machinery.
6004-2Z/C3 GJN Bearing Typical Application Areas
- Electric Motors and Generators: A primary application due to its high-speed capability, effective sealing, and robust load handling.
- Industrial Gearboxes and Transmissions: Used where reliable performance under radial load and moderate axial loads is required.
- Material Handling Equipment: Conveyor rollers, pulleys, and other components benefit from its durability and contamination protection.
- Agricultural and Automotive Auxiliary Machinery: Fans, pumps, and idlers in demanding environments utilize its sealed and pre-lubricated design for extended service intervals.
