1222KJC3 Bearing Product Overview & Core Advantages
The 1222KJC3 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 shaft mounting, enabling it to accommodate significant combined loads—both radial and axial forces. Its double row construction provides enhanced stability and stiffness, making it an ideal choice for machinery where precision and reliability are paramount. The bearing is pre-lubricated and features a generous C3 radial internal clearance, suitable for applications with thermal expansion or heavy loads.
1222KJC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1222 | Standard bearing series designation, indicating a metric double row angular contact ball bearing with a 110mm bore and 200mm outside diameter. |
| K | Indicates a tapered bore with a 1:12 ratio, facilitating precise and secure interference fit on adapter sleeves or withdrawal sleeves. |
| J | Specifies the internal design and cage material, in this case, a pressed steel cage (window-type). |
| C3 | Denotes a greater than normal radial internal clearance. This is crucial for applications involving thermal expansion, high speeds, or heavy loads to prevent binding and ensure optimal performance. |
1222KJC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides superior rigidity and can support substantial radial dynamic loads (19,890 lbf) and static loads (8,775 lbf), effectively handling combined loads.
- Precision Tapered Bore: The K-suffix tapered bore ensures a tight, concentric fit on the shaft, minimizing slippage and vibration under heavy loads or sudden torque changes.
- Optimized for Challenging Conditions: The C3 clearance accommodates thermal expansion and heavy-duty operation, while the standard lubrication ensures immediate readiness for service and reduces initial wear.
- Robust Material Construction: Manufactured from chrome steel for both rings and balls, this bearing offers excellent durability, wear resistance, and a long operational lifespan.
1222KJC3 Bearing Typical Application Areas
This bearing is engineered for robust machinery and systems, including:
- Industrial Gearboxes and power transmission systems
- Vibrating Screens and other material handling equipment
- Agricultural Machinery such as tractors and harvesters
- Pump and Compressor shafts
- Heavy-duty industrial fans and blowers
