1224 M C/3 Bearing Product Overview & Core Advantages
The 1224 M C/3 is a metric double row angular contact ball bearing engineered for exceptional performance in demanding applications. This precision bearing is designed to accommodate combined loads, simultaneously handling significant radial forces and moderate axial loads in both directions. Its double row construction provides high rigidity and stable rotational accuracy, making it ideal for applications requiring robust support and precise shaft guidance. Manufactured from high-grade chrome steel with a brass cage, it offers reliable operation and is pre-lubricated for immediate use.
1224 M C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1224 | Standard bearing series designation, indicating the bearing dimensions (120mm bore, 215mm OD). |
| M | Indicates the bearing is manufactured from brass (messing) for the cage. |
| C/3 | Specifies the radial internal clearance group. C3 denotes a clearance greater than normal (CN), suitable for applications with thermal expansion or interference fits. |
1224 M C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide superior stiffness, enabling the bearing to support substantial radial dynamic load ratings of 26,775 lbf and effectively manage combined loads.
- Optimized for Precision: The machined brass cage ensures precise ball guidance, reduces friction, and contributes to smooth operation at the limiting speed of 4,000 rpm.
- Controlled Internal Clearance: The C3 radial clearance is engineered for applications where shaft and housing fits, or operational heat, may reduce internal clearance, preventing premature failure due to pre-load.
- Robust Material Construction: Components made from chrome steel offer high load capacity and durability, while the open design allows for customized lubrication regimes.
1224 M C/3 Bearing Typical Application Areas
This bearing is suited for a wide range of industrial machinery requiring robust performance and high reliability. Key sectors include:
- Industrial Gearboxes and Transmissions
- Medium-duty Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- General Industrial Machinery with demanding load conditions
