1313 ETN9 Bearing Product Overview & Core Advantages
The 1313 ETN9 is a double row angular contact ball bearing engineered for applications requiring high precision and reliability. This precision bearing is designed to accommodate combined loads, simultaneously handling significant radial loads and moderate axial loads in both directions. Its compact double-row design offers high rigidity, making it an ideal solution for machinery demanding stable and accurate rotational performance. Manufactured with chrome steel components and featuring a nylon cage, it delivers excellent durability and operational efficiency.
1313 ETN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1313 | Standard bearing series designation, indicating specific internal geometry and dimensions. |
| E | Indicates optimized internal design, often for increased load capacity. |
| TN9 | Specifies the cage type: a glass fiber reinforced nylon cage. This design is lightweight, promotes lower friction, and is suitable for high-speed operation. |
1313 ETN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and contact angle provide superior high rigidity, enabling the bearing to effectively support combined loads (radial and axial). This robust construction ensures minimal deflection under load, critical for precision applications.
High-Speed Performance: The TN9 nylon cage is instrumental in achieving a high limiting speed of 6000 rpm. Its lightweight nature reduces centrifugal forces, while its inherent lubricity minimizes friction and heat generation.
Precision & Durability: Manufactured from high-grade chrome steel, the bearing rings and balls offer excellent wear resistance and long service life. The open seal type allows for easy re-lubrication, facilitating maintenance in demanding operational environments within the specified temperature range of -30°C to 110°C.
1313 ETN9 Bearing Typical Application Areas
The 1313 ETN9 is suited for a wide range of industrial machinery where precision, speed, and rigidity are paramount. Key applications include:
- Machine Tool Spindles
- Industrial Gearboxes
- Pumps and Compressors
- Material Handling Equipment
- Precision Agricultural Machinery
