1301 ETN9 Bearing Product Overview & Core Advantages
The 1301 ETN9 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing excels at handling combined loads, supporting significant radial forces while managing axial loads in both directions. Its compact design, featuring a 12 mm bore and 37 mm outside diameter, makes it ideal for space-constrained, high-performance assemblies. Manufactured from chrome steel and equipped with a nylon cage, it delivers exceptional durability and smooth operation.
1301 ETN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1301 | Basic bearing designation indicating the bearing size and series. |
| E | Optimized internal design for enhanced load capacity and reduced noise/vibration. |
| TN9 | Nylon (polyamide) cage, glass fiber reinforced. This design is lightweight, promotes lower friction, and is ideal for high-speed operation. |
1301 ETN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry provide superior high rigidity, enabling the bearing to withstand substantial combined loads (radial and bidirectional axial).
- High-Speed Performance: The lightweight TN9 nylon cage reduces centrifugal forces, lowers operating temperatures, and allows for a high limiting speed of 28,000 rpm, making it a true high-speed bearing.
- Precision & Durability: Manufactured from high-grade chrome steel with tight dimensional tolerances, this bearing ensures consistent performance and long service life in demanding applications.
- Pre-lubricated: The bearing comes pre-lubricated, ensuring immediate readiness for operation and reliable performance within its specified temperature range.
1301 ETN9 Bearing Typical Application Areas
The 1301 ETN9 is engineered for high-performance machinery and precision equipment, including:
- Electric Motors and Small Spindles
- Precision Gearboxes and Transmission Systems
- High-Speed Pumps and Compressors
- Office Automation Equipment and Precision Instruments
