1322K Bearing Product Overview & Core Advantages
The 1322K metric bearing is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precise operation. Featuring a 1:12 tapered bore for secure shaft mounting, this open-type bearing delivers exceptional performance under combined radial and axial loads. Its double row ball construction provides superior stiffness and load-carrying capacity, making it ideal for high-precision machinery where reliable, long-term performance is critical. The bearing comes pre-lubricated and is manufactured from high-grade chrome steel for durability.
1322K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1322 | Standard bearing series designation indicating bore diameter (110mm), outside diameter (240mm), and width (50mm). |
| K | Denotes a tapered bore with a 1:12 taper ratio for precise interference fit on tapered shafts. |
1322K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball design provides significantly increased radial stiffness compared to single row bearings, enabling superior performance under combined loads and moment loads.
- Optimized Internal Geometry: Precision-engineered raceways and ball complement ensure smooth operation and extended service life under demanding conditions.
- Nylon Cage: The lightweight polymer cage reduces centrifugal forces, contributes to lower operating temperatures, and enables higher limiting speeds (3,600 rpm).
- Standard Radial Clearance (CN): Provides optimal internal fit for most industrial applications, balancing temperature management and running precision.
- Tapered Bore Mounting: The 1:12 taper allows for precise axial positioning and creates a secure interference fit when properly mounted, eliminating inner ring creep.
1322K Bearing Typical Application Areas
The 1322K bearing is engineered for heavy-duty industrial equipment requiring robust performance:
- Industrial Gearboxes and power transmission systems
- Material Handling Equipment including conveyor pulleys
- Mining and Construction Machinery components
- Vibrating Screens and processing equipment
