1317 K Bearing Product Overview & Core Advantages
The 1317 K is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precision. This metric bearing excels at supporting substantial radial loads while maintaining operational stability. Its open design, combined with a nylon cage, facilitates high-speed operation, making it a reliable choice for high-performance machinery. The bearing is pre-lubricated for immediate use and features a robust chrome steel construction for enhanced durability and a long service life.
1317 K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1317 | Standard bore diameter code (85 mm) and dimension series. |
| K | Indicates a tapered bore (conicity 1:12), designed for precise mounting on adapter sleeves or withdrawal sleeves for simplified installation and disassembly. |
1317 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior radial stiffness, enabling it to handle significant radial dynamic load ratings of 21,938 lbf. This design is ideal for applications with heavy loads and potential shaft deflections.
- High-Speed Capability: The lightweight nylon cage minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 4,800 rpm, ensuring smooth operation at elevated rotational velocities.
- Precision Tapered Bore: The K-suffix tapered bore ensures a tight, secure fit on the shaft when used with an adapter sleeve, eliminating clearance and enhancing rotational accuracy.
- Pre-Lubricated & Ready-to-Use: Factory-applied lubrication ensures immediate operation and provides protection during the initial run-in period across a wide temperature range from -30°C to 110°C.
1317 K Bearing Typical Application Areas
This bearing is engineered for robust industrial environments. Key applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Vibrating Screens and other heavy-duty machinery
