1226 KM Bearing Product Overview & Core Advantages
The 1226 KM metric ball bearing is a double row angular contact ball bearing designed for robust performance in demanding applications. Its double row construction provides superior high rigidity and enables it to accommodate significant combined loads, including radial and bidirectional axial loads. Manufactured with precision-ground chrome steel components and a lightweight nylon cage, this bearing is engineered for reliable operation, making it an excellent choice for high-precision and high-reliability industrial environments.
1226 KM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1226 | Standard bearing designation indicating a double row bearing with a 130mm bore. |
| KM | Indicates a specific design and tolerance class for the bearing assembly. |
1226 KM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides a significantly stiffer structure compared to single row bearings, offering excellent support against moment loads and high combined loads.
- Optimized Cage Design: The nylon cage ensures smooth operation at high speeds, contributes to lower operating temperatures, and is suitable for the specified temperature range of -30° to 110 °C.
- Precision Ground Components: Manufactured from high-grade chrome steel, the rings and balls guarantee long service life and consistent performance under the dynamic load rating of 28,575 lbf and static load rating of 13,162 lbf.
- Open Design & Lubrication: The open seal type allows for easy re-lubrication, extending service intervals and maintaining performance up to the limiting speed of 3,600 rpm.
1226 KM Bearing Typical Application Areas
This bearing is ideally suited for applications requiring high rigidity and the ability to handle complex loading conditions. Key industries and machinery include:
- Industrial Gearboxes and Transmissions
- Medium-duty Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- General Industrial Machinery with demanding bearing dimensions (130mm bore x 230mm OD).
