The NU226ECM is a specific type of cylindrical roller bearing. Here’s a breakdown of its key features and specifications:
1. Bearing Type: NU Design
- The “NU” indicates that this is a cylindrical roller bearing with two flanges on the outer ring and no flanges on the inner ring. This design allows for axial displacement of the shaft relative to the housing, making it suitable for applications with thermal expansion or misalignment.
2. Dimensions:
- Bore Diameter (d): 130 mm
- Outer Diameter (D): 230 mm
- Width (B): 40 mm
3. ECM Designation:
- EC: Stands for “Optimized Internal Design,” which means the bearing has a higher load-carrying capacity due to improved roller and raceway profiles.
- M: Indicates that the bearing has brass or bronze cages (machined). These cages are robust and suitable for high-speed applications.
4. Load Capacity:
- Dynamic Load Rating (C): Typically around 500 kN (exact value depends on the manufacturer).
- Static Load Rating (C0): Typically around 600 kN (exact value depends on the manufacturer).
5. Speed Rating:
- The bearing is suitable for high-speed applications due to its optimized internal design and brass cage.
6. Applications:
- NU226ECM bearings are commonly used in heavy-duty industrial applications such as:
- Gearboxes
- Electric motors
- Pumps
- Compressors
- Rolling mills
7. Lubrication:
- Proper lubrication is essential for optimal performance. Grease or oil lubrication can be used depending on the operating conditions.
8. Manufacturer Variations:
- Different manufacturers may have slight variations in specifications, so always refer to the manufacturer’s datasheet for precise details.
