6304 TN9/C4 Bearing Product Overview & Core Advantages
The 6304 TN9/C4 is a single row deep groove ball bearing engineered for applications requiring high precision and reliable performance. This metric bearing features a nylon cage (TN9 designation) and enhanced radial internal clearance (C4), making it particularly suitable for applications with thermal expansion considerations. Its open design allows for versatile lubrication options while maintaining excellent radial load capacity and operational stability across a wide temperature range from -30° to 120°C.
6304 TN9/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| TN9 | Nylon cage, glass fiber reinforced | Reduced friction, excellent high-speed capability, and corrosion resistance |
| C4 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications |
6304 TN9/C4 Bearing Structural Features & Performance Benefits
Optimized Cage Design: The TN9 nylon cage provides superior guidance for the balls, reducing friction and enabling higher limiting speeds (14,000 rpm) compared to steel cage alternatives. The cage's lightweight construction minimizes centrifugal forces, contributing to smoother operation.
Enhanced Clearance Configuration: The C4 radial internal clearance allows for thermal expansion in applications where operating temperatures vary significantly, preventing premature failure due to excessive preload.
Precision Manufacturing: Manufactured to ABEC 1/ISO P0 tolerance class with tight dimensional control (bore diameter tolerance: -0.01mm to 0), ensuring consistent performance and easy installation.
Material Excellence: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and durability under radial dynamic load rating of 3574 lbf.
