1310 ETN9/C3 Bearing Product Overview & Core Advantages
The 1310 ETN9/C3 is a double row angular contact ball bearing designed for applications requiring high load capacity and robust performance. This precision bearing excels at simultaneously handling significant combined loads, including radial forces and bidirectional axial loads, thanks to its optimized contact angle and double row design. Its compact bearing dimensions (50 mm bore, 110 mm OD, 27 mm width) make it an ideal choice for space-constrained, high-reliability machinery. The bearing comes pre-lubricated and features a nylon cage for smooth, high-speed operation.
1310 ETN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| E | Optimized internal design | Enhanced load rating and performance |
| TN9 | Nylon cage, stabilizer designation | Reduced friction, excellent high-speed capability, and quieter operation |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with high operating temperatures or heavy loads |
1310 ETN9/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior rigidity and enables the bearing to support substantial combined loads (radial and axial) from both directions, making it more compact than using two single-row bearings.
- High-Speed Performance: The lightweight TN9 nylon cage ensures stable operation and minimal centrifugal forces, contributing to a high limiting speed of 8,000 rpm. The pre-applied lubrication further supports smooth high-speed running.
- Operational Reliability: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers excellent durability and fatigue resistance. The C3 clearance provides operational stability under varying thermal conditions.
1310 ETN9/C3 Bearing Typical Application Areas
This bearing is engineered for demanding industrial environments, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
