1319KJ Bearing Product Overview & Core Advantages
The 1319KJ is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and the ability to support combined loads. Featuring a tapered bore (1:12 ratio) and an open design, this precision bearing is engineered for robust performance in radial load scenarios. Its double row construction provides enhanced stability and load-carrying capacity compared to single row designs, making it an ideal choice for machinery where space constraints and high reliability are critical.
1319KJ Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1319 | Standard bearing series designation, indicating the core dimensions (95mm bore, 200mm OD). |
| K | Denotes a tapered bore with a 1:12 ratio, allowing for precise interference fit on adapter sleeves or tapered shafts. |
| J | Indicates the protrusion of the balls from the bearing side faces, a feature of this specific design. |
1319KJ Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust steel cage provide superior stiffness, enabling the bearing to handle significant radial dynamic loads (29,925 lbf) and radial static loads (11,475 lbf).
- Optimized Internal Geometry: The design, including the specified shoulder diameters and protrusion of the balls, ensures optimal load distribution and operational stability.
- Precision Tapered Bore: The 1:12 tapered bore facilitates a secure and precise mounting, minimizing internal clearance and enhancing overall system accuracy.
- Material & Compliance: Manufactured from high-grade chrome steel for both rings and balls, ensuring durability and long service life. The bearing is compliant with ROHS and REACH regulations.
- Standard Radial Clearance & Lubrication: Supplied with CN group radial internal clearance and pre-lubricated, making it ready for immediate installation in a wide range of industrial applications.
1319KJ Bearing Typical Application Areas
This bearing is suited for heavy-duty machinery and equipment where high radial load capacity and rigidity are paramount. Typical applications include:
- Industrial Gearboxes
- Vibrating Screens and other material handling equipment
- Large Electric Motors
- Pump Systems
- Construction and Mining Machinery
