1309TN Bearing Product Overview & Core Advantages
The 1309TN is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing excels at simultaneously handling significant radial loads and bidirectional axial loads, offering a compact and robust solution. Its construction provides high rigidity and stable operation, making it ideal for machinery requiring high reliability and dimensional accuracy. The optimized internal geometry and high-quality materials contribute to its extended service life and consistent performance.
1309TN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1309 | Standard bearing series designation, indicating the bearing dimensions (45mm bore, 100mm OD). |
| TN | Indicates a Nylon (Polyamide) cage. This lightweight cage is beneficial for high-speed operation, reduces friction, and offers quiet running. |
1309TN Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized contact angle provide superior high rigidity, enabling the bearing to support substantial combined loads (radial and axial) from both directions without sacrificing performance.
- High-Speed Performance: The lightweight TN nylon cage minimizes centrifugal forces, reduces friction, and ensures stable operation, contributing to the high limiting speed of 8,500 rpm.
- Precision & Durability: Manufactured from high-grade Chrome Steel, the bearing rings and balls offer excellent wear resistance and durability. The standard CN radial internal clearance is suited for a wide range of common industrial applications.
- Pre-Lubricated for Immediate Use: The bearing is supplied lubricated, ready for installation and immediate operation, simplifying the mounting process.
1309TN Bearing Typical Application Areas
The 1309TN is engineered for versatility and is commonly specified in:
- Industrial Gearboxes and Transmissions
- Electric Motors and Generators
- Pumps and Compressors
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring robust double row bearings
