1313 K Bearing Product Overview & Core Advantages
The 1313 K is a metric double row angular contact ball bearing designed for exceptional performance in demanding applications. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing excels at handling combined radial and axial loads simultaneously. Its double-row construction provides high rigidity and stability, making it an ideal choice for precision machinery requiring robust support and reliable operation under significant stress.
1313 K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1313 | Standard bearing series designation, indicating the core dimensions (65mm bore, 140mm OD). |
| K | Denotes a tapered bore with a 1:12 taper ratio, enabling precise interference fit on adapter sleeves or withdrawal sleeves for simplified mounting and dismounting. |
1313 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides superior stiffness, effectively supporting combined loads (radial and axial) and moment loads, ensuring stable shaft positioning.
- Optimized Internal Geometry: Precision-ground raceways and high-quality chrome steel components contribute to smooth operation and extended service life.
- Nylon Cage: The lightweight cage reduces centrifugal forces, minimizes friction, and is suitable for the specified temperature range, contributing to reliable high-speed performance.
- Standard Internal Clearance: The CN radial internal clearance is suitable for a wide range of common operating conditions and fits.
- Pre-lubricated: Comes with initial lubrication for immediate operation, reducing initial setup time.
