1222J Bearing Product Overview & Core Advantages
The 1222J metric double row angular contact ball bearing is engineered for applications requiring exceptional rigidity and the capacity to handle significant radial loads. Its double row design provides a compact and robust solution, offering higher load capacity and greater stiffness compared to single row bearings in a similar envelope. Manufactured from high-grade chrome steel, this bearing ensures reliable performance and long service life, making it an ideal choice for demanding industrial environments.
1222J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1222 | Standard bearing series designation indicating the bore diameter (110 mm), outside diameter (200 mm), and width (38 mm). |
| J | Suffix denoting a moderate internal radial clearance (CN group), optimized for general operating conditions. |
1222J Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction significantly increases radial stiffness and enables the bearing to support substantial radial dynamic loads up to 19,890 lbf. This design is inherently more rigid than single row alternatives.
- Optimized Internal Geometry: Precision-ground raceways and balls ensure smooth operation and consistent performance. The specified shoulder diameters on the inner and outer rings facilitate precise axial location.
- Steel Cage & Material Integrity: The pressed steel cage provides robust ball guidance and is suitable for the bearing's limiting speed of 4,300 rpm. Both rings and balls are made from chrome steel (AISI 52100 equivalent), offering excellent wear resistance and durability.
- Standard Radial Clearance (CN): The J-suffix indicates a "Normal" internal clearance, which is versatile for a wide range of applications and typical operating temperatures.
1222J Bearing Typical Application Areas
This bearing is well-suited for machinery and equipment where high radial load capacity and rigidity are paramount. Common applications include:
- Industrial Gearboxes and Transmissions
- Material Handling Conveyor Systems
- Medium-duty Electric Motors
- Agricultural Machinery
- Pumps and Compressors
