1224M Bearing Product Overview & Core Advantages
The 1224M is a double row angular contact ball bearing designed for applications requiring high precision and exceptional rigidity. This precision bearing excels at simultaneously supporting substantial combined loads, including radial forces and bidirectional axial loads. Its compact design, characterized by optimized bearing dimensions (120 mm bore, 215 mm OD, 42 mm width), makes it ideal for space-constrained, high-reliability machinery. Manufactured from chrome steel and featuring a brass cage, it delivers robust performance and long service life.
1224M Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| M | Indicates the bearing is supplied with a specific brass cage, which contributes to high-speed stability and durability. |
| Open (Seal Type) | The bearing features an open design, allowing for custom lubrication schemes to be implemented for optimal performance in specific environments. |
| CN (Radial Clearance) | Specifies the standard radial internal clearance group, providing a balance between operational quietness and thermal expansion management. |
1224M Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide superior high rigidity, enabling the bearing to handle significant radial dynamic load ratings of 26,775 lbf and combined loads effectively.
- Optimized for Performance: The brass cage (M suffix) ensures stable operation at the specified limiting speed of 4,000 rpm, making it suitable for high-speed applications.
- Precision Engineering: Manufactured from chrome steel for both rings and balls, the bearing guarantees high durability and consistent performance. The standard CN radial clearance ensures reliable operation under normal conditions.
- Versatile Lubrication: The open seal type allows for the use of specialized greases or oil systems, providing flexibility to meet specific application temperature ranges (-30°C to 110°C).
1224M Bearing Typical Application Areas
This bearing is ideally suited for demanding industrial environments, including:
- Industrial Gearboxes and Transmissions
- Medium-duty Pump and Compressor Systems
- Material Handling Equipment
- Agricultural and Construction Machinery
