1320K Bearing Product Overview & Core Advantages
The 1320K is a metric double row angular contact ball bearing designed for high-performance industrial applications. Featuring a 1:12 tapered bore for precise shaft mounting, this bearing excels at handling significant radial loads while offering high operational rigidity. Its double row construction provides a compact, space-saving solution with enhanced load-carrying capacity compared to single row designs. Manufactured from high-grade chrome steel with a stainless steel cage, it ensures reliable performance in demanding environments, making it an ideal choice for applications requiring high precision and long service life.
1320K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1 | Series designation, indicating a specific cross-section and size profile. |
| 320 | Bore diameter code (100 mm). |
| K | Indicates a tapered bore with a 1:12 ratio for secure shaft fitting. |
Key Feature: The K suffix is critical, signifying the tapered bore which allows for precise axial positioning and a tight interference fit on the shaft, significantly enhancing system rigidity.
1320K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides superior radial stiffness, enabling the bearing to support heavy radial loads (Dynamic: 32,175 lbf / Static: 12,825 lbf) with minimal deflection. This makes it exceptionally stable under high-stress conditions.
- Optimized for Precision Mounting: The 1:12 tapered bore ensures a precise and secure fit on adapter sleeves or tapered shafts, eliminating internal clearance and maximizing running accuracy.
- Durable Construction: Components made from chrome steel (rings and balls) and a stainless steel cage offer excellent resistance to wear and corrosion, contributing to a long operational lifespan.
- Standard Internal Clearance & Lubrication: Supplied with a standard CN radial internal clearance and pre-lubricated, the bearing is ready for immediate installation and operation within a broad temperature range of -30°C to 110°C.
1320K Bearing Typical Application Areas
The 1320K bearing is engineered for robust machinery and precision systems. Its key characteristics make it suitable for:
- Industrial Gearboxes and Transmissions
- Vibrating Screens and Conveyors
- Agricultural Machinery
- Material Handling Equipment
- Pump and Compressor Systems
Its ability to handle heavy loads and its secure tapered bore fit make it a reliable component in applications where high rigidity and shock resistance are paramount.
