6205 ETN9 Bearing Product Overview & Core Advantages
The 6205 ETN9 is a single row deep groove ball bearing engineered for precision and reliability in demanding applications. This metric bearing features an open design and is manufactured to P6 tolerance class, ensuring high running accuracy and dimensional stability. Its primary advantage lies in its ability to efficiently handle radial loads while offering a high limiting speed of 18,000 rpm, making it an excellent choice for applications requiring smooth operation and durability. The use of a nylon cage (TN9) contributes to lower friction and quieter running, ideal for high-speed scenarios.
6205 ETN9 Bearing Model Code Explained, Specifications & Naming Convention
- 6205: Basic designation for a single row deep groove ball bearing with a 25mm bore and 52mm outside diameter.
- E: Denotes an optimized internal design, often featuring more and/or larger balls, which increases the radial dynamic load rating.
- TN9: Indicates the cage type. TN9 is a glass fiber reinforced nylon cage, which is lightweight, allows for high speeds, and promotes quiet operation with good compatibility with common lubricants.
6205 ETN9 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The TN9 nylon cage is a key contributor to the bearing's high limiting speed. Its lightweight nature reduces centrifugal forces, while its inherent lubricity minimizes friction and heat generation at high RPMs.
- Robust Load Capacity: The E-type design enhancement increases the complement of balls, significantly boosting the radial dynamic load rating (4002 lbf) and static load rating (2091 lbf), providing a robust solution for applications with significant radial forces.
- Precision Performance: Manufactured to a P6 tolerance class with a CN radial internal clearance, this bearing ensures precise shaft positioning, reduced vibration, and consistent performance in precision machinery.
- Material Integrity: Constructed from chrome steel for both rings and balls, the bearing offers high hardness, wear resistance, and a long operational life under standard temperature conditions (-30°C to 120°C).
