6203-ZTN9/C3LHT23 Bearing Product Overview & Core Advantages
The 6203-ZTN9/C3LHT23 is a single row deep groove ball bearing engineered for high performance and reliability in demanding applications. This metric bearing is characterized by its ability to accommodate significant radial loads and moderate axial loads in both directions. Its precision construction and optimized internal geometry ensure smooth operation, low noise, and low torque, making it an ideal choice for applications requiring high rotational accuracy and operational efficiency. The combination of a nylon cage (TN9) and a generous C3 radial internal clearance further enhances its suitability for applications with potential thermal expansion or high-speed requirements.
6203-ZTN9/C3LHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| Z | Shield on one side | Provides effective protection against contaminants while offering low friction. |
| TN9 | Nylon (Polyamide) cage, glass fiber reinforced | Lightweight cage contributes to high-speed capability, low noise, and excellent acceleration characteristics. |
| C3 | Radial internal clearance greater than Normal (CN) | Accommodates thermal expansion in the shaft or housing, preventing preload and ensuring stable operation under varying thermal conditions. |
| LHT23 | High-temperature grease lubrication | Enables reliable performance within a wide temperature range from -30°C to 120°C, offering long-term lubrication stability. |
6203-ZTN9/C3LHT23 Bearing Structural Features & Performance Benefits
Optimized Internal Design: The deep groove raceway and high-precision chrome steel components provide excellent radial load capacity and reliable operation.
High-Speed Performance: The lightweight TN9 nylon cage reduces centrifugal forces, significantly contributing to the bearing's high limiting speed of 17,000 rpm. This makes it a true high-speed bearing.
Robust Load Handling: With a dynamic load rating of 2147 lbf and a static load rating of 1079 lbf, this bearing is built to withstand demanding operational stresses.
Thermal & Operational Stability: The C3 clearance is a critical feature that prevents binding due to thermal expansion, ensuring consistent performance and longevity in applications with fluctuating temperatures.
Long Service Life & Low Maintenance: The combination of a protective shield and high-temperature LHT23 grease provides a sealed, pre-lubricated environment, resulting in a long service life with minimal maintenance requirements.
