The NU2205 EM is a specific type of cylindrical roller bearing. Here’s a breakdown of its key features:
1. 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 where thermal expansion or misalignment might occur.
2. Dimensions: 2205
- The “2205” refers to the bearing’s size designation:
- Bore Diameter (d): 25 milimetr
- Outer Diameter (D): 52 milimetr
- Šířka (B): 18 milimetr
3. Suffix: EM
- The “EM” suffix typically indicates the bearing’s internal design and cage material:
- E: Optimized internal design for higher load capacity.
- M: Indicates the cage material, which is usually machined brass or steel. In this case, it likely refers to a machined brass cage, providing good strength and durability.
4. Applications
- NU2205 EM bearings are commonly used in applications where high radial loads are present, such as:
- Electric motors
- Gearboxes
- Industrial machinery
- Pumps and compressors
5. Key Features
- High radial load capacity
- Accommodates axial displacement
- Suitable for high-speed operations
- Robust construction with a machined brass cage
6. Maintenance
- Regular lubrication is essential to ensure long service life.
- Proper installation and alignment are critical to prevent premature failure.
