1224-KM C/3 Bearing Product Overview & Core Advantages
The 1224-KM C/3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precision. This metric bearing features a 1:12 tapered bore for secure shaft mounting and is optimized to handle significant combined loads, including radial and axial forces. Its double row construction provides a compact, high-capacity solution, making it an excellent choice for high-reliability machinery where space and performance are critical. The bearing is pre-lubricated for immediate use and operates effectively within a wide temperature range.
1224-KM C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| KM | Indicates a tapered bore (1:12) and a withdrawal sleeve for mounting. |
| C | Designates the internal clearance group. "C" corresponds to a CN (Normal) radial internal clearance. |
| /3 | Specifies the cage type. In this case, it indicates a brass cage, which offers excellent strength and is suitable for high-speed operation. |
1224-KM C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design significantly increases the bearing's rigidity and its ability to support substantial radial dynamic loads (26,775 lbf) and radial static loads (11,925 lbf). This makes it exceptionally resistant to deformation under heavy combined loads.
- Precision Tapered Bore: The 1:12 tapered bore ensures a precise and secure interference fit on the shaft, eliminating slippage and maintaining accurate rotational alignment under high torque and load conditions.
- Optimized for Performance: The brass cage (C/3) ensures stable operation at the specified limiting speed of 4,000 rpm. The CN internal clearance provides an optimal balance for most industrial applications, accommodating thermal expansion while maintaining precision.
- Durable Material Construction: Manufactured from chrome steel for both rings and balls, the bearing delivers high wear resistance and long service life. The open design allows for customized re-lubrication strategies to suit specific operational needs.
1224-KM C/3 Bearing Typical Application Areas
This bearing is ideally suited for heavy-duty industrial equipment requiring robust performance and high reliability. Key applications include:
- Industrial Gearboxes and power transmission systems.
- Vibrating Screens and other material handling equipment.
- Heavy-duty Pumps and Compressors.
- Machinery with tapered shaft mountings, such as certain types of agricultural and construction equipment.
