6205 TN9/C4 Bearing Product Overview & Core Advantages
The 6205 TN9/C4 is a single row deep groove ball bearing engineered for high-performance applications requiring precision and reliability. This metric bearing features a C4 radial internal clearance and a TN9 nylon cage, making it particularly suitable for applications with thermal expansion considerations and demanding operational speeds. Its open design allows for versatile lubrication options while maintaining excellent radial load capacity and operational stability across a wide temperature range.
6205 TN9/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| TN9 | Nylon cage, glass fiber reinforced | Enables higher limiting speeds, reduced friction, and excellent acceleration characteristics |
| C4 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with significant temperature variations |
6205 TN9/C4 Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class, ensuring consistent performance and dimensional accuracy for reliable operation in precision applications.
High-Speed Capability: The TN9 nylon cage provides superior high-speed performance with a limiting speed of 13,000 rpm, offering reduced weight and excellent sliding properties for demanding rotational applications.
Thermal Compensation: The C4 radial clearance accommodates differential thermal expansion between shaft and housing, preventing preload conditions that could compromise bearing life in variable temperature environments.
Material Excellence: Constructed from chrome steel for both rings and balls, providing high hardness, wear resistance, and durability under substantial radial dynamic load ratings of 3147 lbf.
