1306 K Bearing Product Overview & Core Advantages
The 1306 K is a double row angular contact ball bearing designed for applications requiring high rigidity and the ability to support combined loads. Its metric design features a tapered bore (1:12) for secure shaft mounting, contributing to precise operation. This precision bearing is characterized by its compact cross-section, offering a robust solution in a minimal space. Manufactured from high-grade chrome steel and featuring a lightweight nylon cage, it is engineered for reliable performance in demanding environments.
1306 K Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| K | Indicates a tapered bore with a 1:12 taper ratio. This allows for precise axial positioning and a tight interference fit on the shaft, enhancing overall system rigidity. |
| (Open) | The bearing is supplied without seals or shields, making it suitable for applications where the operating environment is clean or where custom sealing is implemented. This allows for higher potential speeds. |
1306 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides significantly greater radial and moment load capacity compared to single row bearings, making it ideal for applications with significant combined loads.
- Tapered Bore Advantage: The K suffix denotes a tapered bore. When mounted on a matching adapter sleeve or withdrawal sleeve, it ensures a secure, interference fit that eliminates internal clearance, further increasing system rigidity and rotational accuracy.
- Optimized for Performance: The use of a nylon cage reduces weight and friction, contributing to smoother operation and lower operating temperatures, which is beneficial for the bearing's limiting speed of 13,000 rpm.
- Precision Ground: Manufactured with tight dimensional tolerances on the bore diameter, outside diameter, and width, ensuring consistent performance and ease of installation.
- Standard Clearance & Lubrication: Supplied with a standard CN radial internal clearance and pre-lubricated, ready for immediate use in a wide range of standard applications.
1306 K Bearing Typical Application Areas
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Agricultural Machinery
- Material Handling Equipment (e.g., conveyor pulleys)
