1312 ETN9/C3 Bearing Product Overview & Core Advantages
The 1312 ETN9/C3 is a double row angular contact ball bearing designed for applications requiring high load capacity and rigid support. This precision bearing excels at handling combined loads, simultaneously supporting substantial radial loads and axial loads in both directions. Its compact design, featuring two rows of balls, provides exceptional high rigidity, making it ideal for high-reliability machinery. The optimized internal geometry and C3 radial internal clearance ensure stable performance under varying operational conditions and temperatures.
1312 ETN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1312 | Standard bearing series designation, indicating the bearing dimensions (60mm bore, 130mm OD, 31mm width). |
| E | Optimized internal design for enhanced load capacity and performance. |
| TN9 | Polyamide (Nylon) cage, glass fiber reinforced. This cage material contributes to lower friction, quieter operation, and is suitable for high-speed applications. |
| /C3 | Indicates a radial internal clearance greater than normal (C0). This is beneficial for applications with thermal expansion or where interference fits are used. |
1312 ETN9/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior rigidity and enables the bearing to handle significant combined loads (radial and axial) effectively, making the system more stable.
- High-Speed Performance: The lightweight and robust TN9 nylon cage minimizes centrifugal forces and ensures smooth operation, supporting the high limiting speed of 6,300 rpm.
- Precision & Durability: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers excellent wear resistance and long service life under demanding conditions.
- Operational Flexibility: The C3 clearance allows for accommodation of thermal expansion and press fits, reducing the risk of premature failure due to excessive preload.
1312 ETN9/C3 Bearing Typical Application Areas
This bearing is engineered for robust performance in a wide range of industrial sectors, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
