1224-M-C3 Bearing Product Overview & Core Advantages
The 1224-M-C3 is a double row angular contact ball bearing designed for demanding industrial applications. This precision bearing excels at simultaneously handling significant combined loads, including radial forces and bidirectional axial loads. Its compact double row construction provides exceptional high rigidity and stability, making it ideal for machinery requiring high operational reliability and precision. The bearing comes pre-lubricated and features a generous C3 radial internal clearance, accommodating thermal expansion in high-speed or high-temperature environments.
1224-M-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1224 | Standard bearing designation indicating bore diameter (120mm), outside diameter, and width series. |
| M | Indicates the use of a brass cage (machined), which provides superior strength and guidance at high speeds. |
| C3 | Specifies a greater than normal radial internal clearance. This is critical for applications with high thermal gradients or where interference fits are used, preventing preload and potential seizure. |
1224-M-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball design and robust construction provide significantly higher rigidity and load-carrying capacity compared to single row bearings. It is engineered to support substantial combined radial and axial loads from both directions.
- Optimized for Demanding Conditions: The machined brass cage (M) ensures reliable performance and stability at the bearing's limiting speed of 4000 rpm. The C3 clearance is a key feature that accommodates shaft expansion, making it suitable for high-speed and high-temperature operations.
- Durability and Precision: Manufactured from chrome steel for both rings and balls, the bearing offers high fatigue life and wear resistance. The precision bearing dimensions and tight tolerances ensure consistent performance in high-precision applications.
1224-M-C3 Bearing Typical Application Areas
This bearing is commonly specified in heavy-duty industrial machinery where high rigidity and the ability to handle complex loads are paramount. Key sectors include:
- Industrial Gearboxes and Transmissions
- Heavy-Duty Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural and Construction Machinery
- Mining Equipment
