1317K Bearing Product Overview & Core Advantages
The 1317K metric ball bearing is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precision. Its double row construction enables it to support significant combined loads, handling both radial and axial forces simultaneously. Featuring a tapered bore (1:12) for secure shaft mounting and manufactured from high-grade chrome steel, this bearing is engineered for high reliability and long service life in precision machinery.
1317K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1317 | Standard bore diameter code (85 mm) and series designation. |
| K | Indicates a tapered bore with a 1:12 ratio, facilitating precise interference fits on adapter sleeves or withdrawal sleeves. |
1317K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides superior rigidity, effectively supporting heavy combined loads and moment loads. The radial dynamic load rating of 21,938 lbf ensures robust performance under demanding conditions.
- Precision Tapered Bore: The K-suffix tapered bore ensures a tight, secure fit on the shaft, minimizing slippage and maintaining precise alignment for high-precision applications.
- Optimized for Speed: The stainless steel cage and optimized internal geometry contribute to a high limiting speed of 4,800 rpm, making it suitable for high-speed operation.
- Standard Internal Clearance: The CN radial internal clearance is the standard group, offering a versatile balance for most general applications.
- Pre-lubricated & Ready-to-Use: The bearing comes lubricated from the factory, ensuring immediate operation and reducing initial setup time.
1317K Bearing Typical Application Areas
This 1317K bearing is ideally suited for industrial machinery where high precision, rigidity, and reliability are paramount. Key application areas include:
- Machine Tool Spindles
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Precision Agricultural Machinery
