6004 TN9/C4 Bearing Product Overview & Core Advantages
The 6004 TN9/C4 is a single row deep groove ball bearing engineered for high-performance radial load applications. Characterized by its open design and precision ABEC 1 (ISO P0) tolerance, this bearing delivers reliable operation and consistent performance. A key feature is its optimized C4 radial internal clearance, which accommodates thermal expansion in demanding applications, making it suitable for environments with significant temperature variations. Its robust construction from chrome steel ensures durability and long service life.
6004 TN9/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| TN9 | Indicates a glass fiber reinforced nylon cage (PA66-GF25). This cage design contributes to low friction, quiet operation, and is ideal for high-speed applications. |
| C4 | Specifies a greater than normal radial internal clearance. This is critical for applications involving thermal expansion or where fits result in a reduction of internal clearance. |
6004 TN9/C4 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of the low-friction nylon TN9 cage and the open design allows for a high limiting speed of 17,000 rpm, making it an excellent high-speed bearing.
- Radial Load Capacity: Designed primarily for radial loads, it features a dynamic load rating of 2113 lbf and a static load rating of 1135 lbf, providing reliable support in various mechanical systems.
- Thermal Stability: The specified C4 clearance ensures consistent performance by compensating for dimensional changes due to heat generation, preventing binding and premature failure.
- Precision & Reliability: Manufactured to ABEC 1 precision class, it guarantees smooth running and minimal vibration, which is essential for the overall accuracy of the assembly.
6004 TN9/C4 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial applications, including:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Power Tools and Appliance Motors
- Conveyor Systems and Material Handling Equipment
- General machinery requiring a reliable, high-speed radial ball bearing.
