1306 EKTN9/C3 Bearing Product Overview & Core Advantages
The 1306 EKTN9/C3 is a metric double row angular contact ball bearing engineered for high-performance applications requiring robust support for combined radial loads. Featuring a 1:12 tapered bore for precise shaft mounting, this bearing delivers exceptional rigidity and stability. Its open design, combined with a nylon cage (TN9) and C3 radial internal clearance, makes it suitable for demanding industrial environments where high precision and reliability are paramount.
1306 EKTN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1306 | Standard bearing designation indicating metric dimensions (30mm bore, 72mm OD, 19mm width) |
| EK | Optimized internal design with 1:12 tapered bore for enhanced mounting precision |
| TN9 | Glass fiber reinforced nylon cage providing excellent high-speed capability and reduced friction |
| C3 | Greater radial internal clearance than normal group, suitable for applications with thermal expansion or heavy loads |
1306 EKTN9/C3 Bearing Structural Features & Performance Benefits
Double Row Construction: The dual raceway design provides significantly higher radial load capacity and superior rigidity compared to single row bearings, making it ideal for applications with substantial radial forces.
High-Speed Capability: The TN9 nylon cage ensures smooth operation at elevated speeds (up to 13,000 rpm) while maintaining dimensional stability and reducing centrifugal forces.
Tapered Bore Design: The 1:12 tapered bore enables precise interference fit on tapered shafts, ensuring secure mounting and eliminating inner ring creep under heavy loads.
Optimized Internal Clearance: The C3 radial clearance accommodates thermal expansion in high-temperature applications and provides optimal performance under heavy load conditions.
Premium Materials: Manufactured from chrome steel for both rings and balls, ensuring high durability, wear resistance, and consistent performance across the operating temperature range of -30°C to 110°C.
