2205 ETN9/C3 Bearing Product Overview & Core Advantages
The 2205 ETN9/C3 is a double row angular contact ball bearing engineered for applications requiring high precision and reliable performance under combined loads. This metric bearing features an open design with a nylon cage and is pre-lubricated for immediate operation. Its primary advantage lies in its ability to simultaneously support significant radial loads and moderate axial loads in both directions, making it an ideal, compact solution for machinery demanding high rigidity and operational stability. The C3 radial internal clearance further enhances its suitability for applications with thermal expansion or demanding operating conditions.
2205 ETN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
The model number 2205 ETN9/C3 is decoded as follows:
- 2205: Basic designation indicating a double row angular contact ball bearing with a 25 mm bore and 52 mm outside diameter.
- E: Designates an optimized internal design, typically featuring reinforced construction and increased load capacity.
- TN9: Signifies the cage material and type. T indicates a glass fiber reinforced polyamide (Nylon) cage, and N9 denotes a specific cage design and locking mechanism, contributing to low friction, quiet operation, and suitability for high-speed applications.
- C3: Specifies a greater than normal radial internal clearance. This is beneficial for applications where thermal expansion of the shaft and housing is expected, or where heavy interference fits are used, preventing pre-load and potential bearing seizure.
2205 ETN9/C3 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The double row design provides a significantly wider effective contact area compared to single row bearings. This results in superior rigidity and the ability to handle substantial combined radial and axial loads from both directions, ensuring stable shaft support and reduced deflection.
- Optimized High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces and reduces friction, allowing for a high limiting speed of 18,000 rpm. This makes the bearing an excellent choice for demanding, high-rotation applications.
- Pre-Lubricated for Longevity: The bearing comes pre-lubricated, ensuring immediate startup and smooth initial operation. This, combined with the open design, allows for easy re-lubrication to extend service life in continuous operation.
- Precision Manufacturing: Manufactured from high-grade chrome steel for both rings and balls, the bearing offers high durability and wear resistance. The tight dimensional tolerances on the bore, outside diameter, and width guarantee precise fit and reliable performance in high-precision assemblies.
