1222 K Bearing Product Overview & Core Advantages
The 1222 K is a double row angular contact ball bearing designed for applications requiring high radial load capacity and rigid shaft support. This precision bearing features an open design and is pre-lubricated, offering reliable performance in a compact form factor. Its construction is optimized to handle significant radial loads, making it an excellent choice for demanding industrial environments where high rigidity and operational reliability are paramount.
1222 K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1222 | Standard bearing designation indicating a metric series double row bearing with a 110 mm bore diameter. |
| K | Denotes a tapered bore (conicity 1:12), enabling precise axial adjustment and secure mounting on adapter sleeves or withdrawal sleeves. |
1222 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide superior radial stiffness, enabling the bearing to support high radial loads with minimal deflection.
- Precision Tapered Bore (K-designation): The conical bore allows for precise clearance adjustment during mounting, ensuring optimal preload and alignment for enhanced running accuracy.
- Optimized Cage Design: The nylon cage contributes to smooth operation, reduced friction, and is suitable for the bearing's limiting speed of 4,300 rpm.
- Material & Compliance: Manufactured from chrome steel for both rings and balls, ensuring high durability and fatigue resistance. The bearing is compliant with ROHS and REACH regulations.
1222 K Bearing Typical Application Areas
This bearing is ideally suited for machinery and systems requiring robust radial support and a tapered bore for secure mounting. Common applications include:
- Industrial Gearboxes
- Vibrating Screens and Conveyors
- Agricultural Machinery
- Material Handling Equipment
- Pump and Compressor Systems
