6204-2Z/GJNVQ086 Bearing Product Overview & Core Advantages
The 6204-2Z is a single row deep groove ball bearing designed for outstanding performance in a wide range of industrial applications. Its key advantage lies in its ability to efficiently handle radial loads while also accommodating moderate axial loads in both directions. The inclusion of shielded construction on both sides protects the bearing's interior from contaminants, enhancing its operational reliability and service life. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers a cost-effective solution for applications requiring consistent performance and high reliability.
6204-2Z/GJNVQ086 Bearing Model Code Explained, Specifications & Naming Convention
| Model Suffix | Technical Meaning | Significance & Advantage |
|---|---|---|
| 6204 | Standard bore diameter code (20 mm) | Indicates a standard metric size, ensuring broad interchangeability and availability. |
| 2Z | Non-contact steel shields on both sides | Provides effective protection against dust and other particulate contaminants while maintaining low friction and high-speed capability. |
6204-2Z/GJNVQ086 Bearing Structural Features & Performance Benefits
- Robust Construction: Built entirely from chrome steel for the rings, balls, and cage, this bearing ensures high strength, durability, and resistance to wear.
- Optimized Load Capacity: The deep groove raceway and high-quality steel construction enable a radial dynamic load rating of 2878 lbf and a static load rating of 1495 lbf, making it suitable for demanding applications.
- High-Speed Performance: With a limiting speed of 15,000 rpm, the bearing is capable of operating in high-velocity scenarios. The non-contact shields and steel cage contribute to this performance by minimizing friction and centrifugal forces.
- Standard Internal Clearance: The CN radial internal clearance is a standard fit for most common operating conditions, providing a balance between temperature management and running precision.
- Maintenance Consideration: The bearing is supplied without lubrication, offering flexibility for the user to apply a specific grease or oil suited to their operational environment and temperature range (-30°C to 120°C).
6204-2Z/GJNVQ086 Bearing Typical Application Areas
This versatile deep groove ball bearing is widely used across numerous industries due to its balanced performance characteristics. Common applications include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
