1316K Bearing Product Overview & Core Advantages
The 1316K metric ball bearing is a double row angular contact ball bearing engineered for demanding applications requiring high load capacity and rigidity. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing is designed to accommodate significant combined loads, including substantial radial forces. Its robust double row construction provides exceptional stability and stiffness, making it an ideal choice for machinery where precision and reliability are paramount. The open design allows for versatile lubrication options to suit specific operational needs.
1316K Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 1316 | Standard bore diameter (80 mm) and series designation. |
| K | Indicates a tapered bore with a 1:12 ratio for precise interference fit on the shaft. |
1316K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design significantly increases radial load-carrying capacity and provides superior rigidity against moment loads, ensuring stable operation under combined loads.
- Precision Tapered Bore: The 1:12 tapered bore ensures a tight, secure fit on a tapered shaft adapter, eliminating internal clearance and enhancing system precision.
- Optimized Material Selection: Components made from Chrome Steel (rings and balls) and a Stainless Steel cage offer excellent durability, corrosion resistance, and reliable performance.
- Standard Internal Clearance: Supplied with a CN (Normal) group radial internal clearance, providing a versatile balance for a wide range of operating conditions.
1316K Bearing Typical Application Areas
This bearing is suited for heavy-duty industrial applications, including:
- Industrial Gearboxes and power transmission systems.
- Vibrating Screens and other material handling equipment.
- Agricultural Machinery such as tractor wheel hubs.
- Pump and Compressor shafts requiring a secure tapered fit.
