1207KTNGC3 Bearing Product Overview & Core Advantages
The 1207KTNGC3 is a metric double row angular contact ball bearing engineered for applications requiring high radial load capacity and precise operation. Featuring a 1:12 tapered bore for secure shaft mounting and C3 radial internal clearance for optimal performance under thermal expansion, this bearing delivers exceptional rigidity and stability. Its nylon cage construction and factory-applied lubrication ensure smooth operation across a wide temperature range (-30° to 110°C), making it ideal for demanding industrial environments where reliability is critical.
1207KTNGC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1207 | Basic bearing designation (35mm bore, 72mm OD) |
| K | 1:12 tapered bore for precise shaft fitting |
| TN | Nylon cage for reduced friction and quiet operation |
| C3 | Greater radial internal clearance for thermal expansion compensation |
1207KTNGC3 Bearing Structural Features & Performance Benefits
Double Row Design: The dual angular contact configuration provides enhanced rigidity and moment load capacity, significantly improving system stability compared to single row bearings.
Optimized Load Distribution: With a radial dynamic load rating of 4275 lbf and precise bearing dimensions (35mm bore × 72mm OD × 17mm width), this bearing efficiently handles substantial radial loads while maintaining dimensional accuracy.
High-Speed Capability: The nylon cage (TN) and factory lubrication enable operation at limiting speeds up to 13,000 rpm, making it suitable for high-speed applications requiring minimal vibration.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances (bore: -0.012mm to 0), this bearing ensures consistent performance and long service life in precision machinery.
1207KTNGC3 Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Machine Tool Spindles requiring high precision and rigidity
- Agricultural Machinery and heavy-duty equipment
