1222KC3 Bearing Product Overview & Core Advantages
The 1222KC3 is a double row angular contact ball bearing designed for demanding industrial applications requiring high precision and reliability. This metric system bearing features a tapered bore (1:12) for secure mounting on adapter sleeves or withdrawal sleeves. Its double row construction enables it to handle significant radial loads while maintaining high rigidity. Manufactured from premium chrome steel with a stainless steel cage, it offers excellent durability. The bearing comes pre-lubricated and features a generous C3 radial internal clearance, making it suitable for applications with thermal expansion or where a tighter fit is required.
1222KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1222 | Basic bearing designation indicating bore diameter (110 mm), outside diameter (200 mm), and width (38 mm) series. |
| K | Denotes a tapered bore with a 1:12 taper ratio for mounting on adapter sleeves. |
| C3 | Indicates a greater radial internal clearance than normal (C0), suitable for applications with thermal expansion or interference fits. |
1222KC3 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 radial static loads (8,775 lbf), making it ideal for heavy-duty applications.
- Precision Tapered Bore: The K-designation tapered bore ensures precise, secure mounting on shafts using adapter sleeves, reducing slippage and improving operational stability.
- Optimized for Thermal Conditions: The C3 internal clearance accommodates thermal expansion during operation, preventing premature failure due to overheating and ensuring consistent performance.
- Durable Construction: Components made from chrome steel and a stainless steel cage provide excellent corrosion resistance and longevity, even in harsh environments.
- Ready-to-Use: The bearing is pre-lubricated, reducing initial setup time and ensuring smooth operation from installation.
1222KC3 Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Material Handling Equipment such as conveyor pulleys
- Agricultural Machinery including tractor gearboxes
- Mining Equipment requiring robust bearing solutions
