1320KJ Bearing Product Overview & Core Advantages
The 1320KJ is a metric double row angular contact ball bearing engineered for demanding applications requiring high precision and reliability. Featuring a tapered bore (1:12) for precise mounting on tapered shafts, this bearing excels at handling significant radial loads. Its double row ball construction provides superior rigidity and stability, making it an ideal choice for machinery where accurate rotational motion is critical. The open design allows for customizable sealing and lubrication solutions to meet specific operational environments.
1320KJ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1320 | Standard bore diameter code (100 mm) and series designation. |
| K | Indicates a tapered bore with a 1:12 ratio for secure, interference-fit mounting. |
| J | Specifies the internal radial clearance group is CN (Normal). |
1320KJ Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design provides exceptional stiffness, enabling the bearing to support substantial radial loads (Dynamic: 32,175 lbf / Static: 12,825 lbf) without significant deformation.
- Precision Tapered Bore: The 1:12 tapered bore ensures a tight, concentric fit on mating shafts, minimizing runout and enhancing rotational accuracy.
- Optimized Material & Construction: Manufactured from chrome steel for rings and balls, and a steel cage, this bearing offers excellent durability and wear resistance under high-stress conditions.
- Standard Internal Clearance: The CN (Normal) radial internal clearance is suitable for a wide range of operating conditions and ensures consistent performance.
1320KJ Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for heavy-duty industrial equipment, including:
- Industrial Gearboxes and power transmission systems
- Machine Tool Spindles requiring high precision and rigidity
- Vibrating Screens and other material handling machinery
- Pump and Compressor shafts
