6005 TN9/C3 Bearing Product Overview & Core Advantages
The 6005 TN9/C3 is a single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. This metric bearing features an open design without seals, making it suitable for applications where external sealing is provided separately. Its key advantages include the ability to handle significant radial loads while maintaining stable operation at moderate speeds. The combination of nylon cage construction and C3 radial internal clearance ensures optimal performance in applications with thermal expansion or shaft misalignment. Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing delivers consistent precision for industrial applications.
Model Code Detailed Explanation
| Code Segment | Technical Meaning | Performance Benefit |
| 6005 | Standard deep groove ball bearing series with 25mm bore, 47mm OD, 12mm width | Standard dimensions for easy replacement and interchangeability |
| TN9 | Nylon cage (polyamide) design | Reduced friction, lighter weight, and excellent high-speed capability |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and shaft misalignment, preventing premature failure |
6005 TN9/C3 Bearing Structural Features & Performance Benefits
Optimized Cage Design: The TN9 nylon cage provides superior performance in high-speed applications, offering reduced weight and excellent sliding properties that contribute to the bearing's limiting speed of 15,000 rpm.
Enhanced Load Capacity: With a dynamic load rating of 2,271 lbf and static load rating of 1,315 lbf, this bearing delivers reliable performance under substantial radial loads while maintaining dimensional stability.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance standards with tight dimensional tolerances (bore: -0.01mm to 0, OD: -0.011mm to 0), ensuring consistent performance and easy installation.
Thermal Compensation: The C3 radial clearance allows for thermal expansion in applications with operating temperatures ranging from -30°C to 120°C, preventing binding and ensuring smooth operation.
Material Excellence: Constructed from chrome steel for both rings and balls, providing excellent hardness, wear resistance, and durability in demanding industrial environments.
6005 TN9/C3 Bearing Typical Application Areas
- Electric Motors: Ideal for small to medium-sized motors requiring high-speed operation and reliable radial load support
- Industrial Gearboxes: Suitable for power transmission systems where thermal expansion must be accommodated
- Material Handling Equipment: Conveyor systems, pulleys, and rollers benefiting from the C3 clearance for misalignment compensation
- Agricultural Machinery: Implement drives and auxiliary systems requiring robust radial bearing performance
- Pumps and Compressors: Applications where separate sealing is provided and high-speed capability is essential
- General Industrial Machinery: Various rotating equipment where standard dimension bearings with enhanced clearance are required
