1320-K C/4 Bearing Product Overview & Core Advantages
The 1320-K C/4 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 is designed to accommodate combined radial and axial loads simultaneously. Its double-row construction provides high rigidity and stable rotational accuracy, making it an ideal choice for high-precision machinery. Manufactured from high-grade chrome steel and featuring a stainless steel cage, it delivers reliable operation and long service life.
Model Code Breakdown
The 1320-K C/4 model designation provides key technical information:
- 1320: Standard bearing series designation, indicating the basic dimensions (100mm bore, 215mm OD).
- K: Denotes a tapered bore with a 1:12 taper ratio.
- C/4: Indicates the radial internal clearance group. In this case, it corresponds to the "CN" group, which is a standard, normal clearance for general applications.
1320-K C/4 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides superior rigidity and can support significant combined radial and axial loads, ensuring stable operation under heavy-duty conditions.
- Precision Tapered Bore: The 1:12 tapered bore allows for precise axial positioning and secure interference fit on a tapered shaft adapter, minimizing inner ring creep and ensuring optimal performance.
- Optimized Material Selection: The use of chrome steel for rings and balls, combined with a durable stainless steel cage, ensures high strength, corrosion resistance, and reliable operation at the specified limiting speed of 4000 rpm.
- Standard Internal Clearance: The C/4 (CN) radial internal clearance is optimized for a wide range of industrial applications, providing a balance between operational temperature and preload requirements.
1320-K C/4 Bearing Typical Application Areas
This bearing is commonly specified in applications requiring high rigidity and precise mounting, including:
- Industrial Gearboxes and power transmission systems
- Machine Tool Spindles and other precision machinery
- Vibrating Screens and other material handling equipment
- Agricultural Machinery and heavy-duty off-road vehicles
