1310 EKTN9/C3 Bearing Product Overview & Core Advantages
The 1310 EKTN9/C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and the ability to support combined loads. Featuring a tapered bore (1:12 ratio) and an open design, this precision bearing is engineered for robust performance. Its double row construction provides excellent stability, making it suitable for high-reliability scenarios where space is constrained. Pre-lubricated and featuring a C3 radial internal clearance, it is optimized for operational conditions with thermal expansion considerations.
1310 EKTN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1310 | Basic bearing designation, indicating the bearing size (50mm bore, 110mm OD). |
| EK | Designates an optimized internal design and a tapered bore (1:12). |
| TN9 | Indicates the cage is made of Nylon (Polyamide 66), contributing to lower friction, quieter operation, and suitability for higher speeds. |
| /C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications with significant thermal gradients or where interference fits are used, preventing preload and potential seizure. |
1310 EKTN9/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide high radial and moment load capacity, ensuring stable operation under combined loads.
- Optimized for Mounting: The tapered bore allows for precise axial positioning and secure mounting on adapter sleeves or tapered shafts, simplifying installation and enhancing system accuracy.
- High-Speed Performance: The lightweight Nylon (TN9) cage reduces centrifugal forces, lowers friction, and enables a high limiting speed of 8,000 rpm, making it a capable high-speed bearing.
- Ready-to-Use & Durable: The bearing is pre-lubricated and features an open design, making it immediately ready for service within its specified temperature range of -30°C to 110°C. The Chrome Steel rings and balls ensure long service life and high durability.
