1315-K C/3 Bearing Product Overview & Core Advantages
The 1315-K C/3 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and precision. Featuring a tapered bore (1:12), this bearing is designed for precise interference fits on adapter sleeves or withdrawal sleeves, ensuring secure shaft mounting. Its double row design provides superior radial load capacity and can accommodate combined loads, making it an ideal choice for robust industrial machinery. Manufactured from high-grade chrome steel and featuring a stainless steel cage, it delivers reliable performance in demanding environments.
1315-K C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| K | Indicates a tapered bore with a 1:12 ratio, facilitating precise mounting and dismounting. |
| C/3 | Specifies the radial internal clearance group (CN - Normal clearance), optimized for typical operating conditions. |
1315-K C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides exceptional stiffness, enabling it to handle significant radial loads (17,842 lbf dynamic rating) and moderate combined loads, ensuring stable operation under stress.
- Precision Tapered Bore: The 1:12 tapered bore allows for precise axial positioning and a secure fit on the shaft, minimizing slippage and vibration, which is critical for high-speed applications (limiting speed of 5,600 rpm).
- Optimized Material Selection: Components made from chrome steel and a stainless steel cage offer excellent durability, corrosion resistance, and longevity, suitable for a wide temperature range (-30°C to 110°C).
- Standard Internal Clearance: The C3 (CN) radial internal clearance is suited for most industrial applications, providing a balance between fit, thermal expansion, and operational smoothness.
1315-K C/3 Bearing Typical Application Areas
This double row angular contact ball bearing is widely used in heavy-duty and precision machinery, including:
- Industrial Gearboxes and power transmission systems
- Vibrating Screens and material handling equipment
- Pump & Compressor shafts requiring high radial load support
- Agricultural Machinery and construction equipment
- Paper & Pulp Processing machinery
