1318KJC3 Bearing Product Overview & Core Advantages
The 1318KJC3 is a double row angular contact ball bearing designed for demanding industrial applications requiring high load capacity and rigidity. This metric bearing features a tapered bore (1:12) for secure mounting on adapter sleeves or withdrawal sleeves, ensuring precise shaft fixation. Its double row construction enables it to support significant combined loads—simultaneously handling substantial radial loads and axial loads in both directions. With a C3 radial internal clearance, it is optimized for applications with thermal expansion or where interference fits are used, making it a robust choice for high-performance machinery.
1318KJC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1318 | Standard bearing series designation, indicating the basic dimensions: 90mm bore, 190mm OD, 43mm width. |
| K | Indicates a tapered bore with a 1:12 taper ratio. |
| J | Specifies the internal design and rolling element guidance. |
| C3 | Denotes a greater than normal radial internal clearance, suitable for applications with thermal gradients or heavy interference fits. |
1318KJC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides superior stiffness and enables the bearing to handle high radial dynamic load ratings of 26,325 lbf and static load ratings of 9,900 lbf. This makes it exceptionally capable of managing combined loads in demanding operational environments.
Optimized for Challenging Conditions: The specified C3 clearance accommodates thermal expansion and interference fits, preventing premature failure. The steel cage ensures reliable performance at the specified limiting speed of 4,500 rpm.
Durability and Precision: Manufactured from chrome steel for both rings and balls, the bearing offers excellent wear resistance and longevity. The open seal type allows for easy re-lubrication, while the pre-lubrication extends service life within the operating temperature range of -30°C to 110°C.
1318KJC3 Bearing Typical Application Areas
The 1318KJC3 is ideally suited for heavy-duty industrial machinery where high load capacity and rigidity are paramount. Key applications include:
- Industrial Gearboxes and power transmission systems
- Vibrating Screens and other material handling equipment
- Pump and Compressor shafts
- Agricultural Machinery and construction equipment
- Heavy-duty Electric Motors requiring a tapered bore fit
