1306KTN Bearing Product Overview & Core Advantages
The 1306KTN is a metric double row angular contact ball bearing engineered for exceptional performance in demanding applications. Featuring a 1:12 tapered bore for precise shaft mounting, this bearing delivers high rigidity and reliable operation under combined radial loads. Its optimized internal geometry and nylon cage contribute to smooth, high-speed operation up to 13,000 rpm, making it an ideal solution for precision machinery requiring superior running accuracy and stability.
1306KTN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1306 | Standard bearing series designation indicating bearing dimensions (30mm bore, 72mm OD, 19mm width) |
| K | Identifies tapered bore with 1:12 taper ratio for secure shaft fitting |
| TN | Specifies nylon cage construction for reduced weight, lower friction, and superior high-speed performance |
1306KTN Bearing Structural Features & Performance Benefits
Double Row Design: The dual ball complement arrangement provides enhanced radial load capacity and superior rigidity compared to single row bearings, ensuring stable operation under demanding conditions.
Precision Tapered Bore: The 1:12 taper enables precise interference fit on tapered shafts, eliminating clearance and improving running accuracy while facilitating installation and removal.
High-Speed Nylon Cage: The TN nylon cage offers excellent strength-to-weight ratio, reducing centrifugal forces and enabling higher limiting speeds while providing quiet operation and corrosion resistance.
Optimized Internal Clearance: Standard CN radial clearance ensures proper preload conditions and thermal expansion compensation, delivering consistent performance across the operating temperature range.
