2205 ETN9/W64 Bearing Product Overview & Core Advantages
The 2205 ETN9/W64 is a double row angular contact ball bearing engineered for high-performance applications demanding exceptional rigidity and reliability. This precision bearing is designed to accommodate combined loads—simultaneously handling significant radial loads and axial loads in both directions. Its compact design, featuring two rows of balls, provides a high load-carrying capacity within a minimal cross-section. Pre-lubricated for long-term performance, it is an ideal solution for high-rigidity and high-speed applications where operational stability is critical.
2205 ETN9/W64 Bearing Model Code Explained, Specifications & Naming Convention
- 2205: Basic designation indicating a double row angular contact ball bearing with a 25 mm bore diameter and 52 mm outside diameter.
- E: Denotes an optimized internal design, typically featuring a larger ball complement and modified raceway geometry for increased load capacity.
- TN9: Signifies the cage material and type. The TN9 suffix indicates a glass fiber reinforced polyamide (Nylon) cage, which is lightweight, promotes smooth operation, and is suitable for high-speed applications.
- W64: Indicates that the bearing is pre-lubricated with a specific, high-performance synthetic grease. This grease is formulated for a wide temperature range and extended service life.
2205 ETN9/W64 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness compared to single row bearings, making it exceptionally resistant to deflection under combined loads. This ensures precise shaft positioning and stable operation.
High-Speed Performance: The lightweight TN9 polymer cage reduces centrifugal forces and inertial mass, enabling higher limiting speeds and smoother rotation with less friction and heat generation.
Reduced Maintenance & Long Service Life: Being pre-lubricated with W64 grease, the bearing is effectively lubricated for life under normal operating conditions within its specified temperature range. This eliminates the need for re-lubrication, reducing maintenance requirements and downtime.
Precision & Reliability: Manufactured from high-grade chrome steel and held to strict dimensional tolerances, this bearing ensures consistent performance, low noise, and high operational reliability in demanding environments.
2205 ETN9/W64 Bearing Typical Application Areas
