The NU2307ECP is a specific type of cylindrical roller bearing. Here’s a breakdown of its designation and key features:
1. NU Designation:
- NU indicates the type of cylindrical roller bearing. In this case:
- NU means the bearing has two fixed ribs on the outer ring and no ribs on the inner ring. This allows the inner ring to move axially relative to the outer ring, making it suitable for applications where thermal expansion or shaft misalignment might occur.
2. 2307:
- 23 refers to the series of the bearing, which indicates its dimensions and load-carrying capacity.
- 07 specifies the bore diameter. For metric bearings, the bore diameter is calculated as:
- Bore diameter = 07 × 5 mm = 35 χιλ..
3. ECP:
- EC: Stands for Optimized Internal Design. This means the bearing has an enhanced internal geometry, providing higher load capacity and better performance.
- P: Indicates the bearing’s cage type. In this case, P refers to a glass fiber-reinforced polyamide (nylon) cage. This type of cage is lightweight, reduces friction, and is suitable for high-speed applications.
4. Key Features:
- High Radial Load Capacity: Cylindrical roller bearings are designed to handle high radial loads.
- Axial Displacement: The NU design allows for axial displacement of the shaft relative to the housing.
- Suitable for High Speeds: The polyamide cage (ECP) makes it suitable for high-speed applications.
- Optimized Internal Design: The EC designation ensures improved performance and load distribution.
5. Applications:
- NU2307ECP bearings are commonly used in:
- Electric motors
- Gearboxes
- Industrial machinery
- Pumps
- Compressors
- Any application requiring high radial load capacity and axial displacement.
6. Dimensions:
- The exact dimensions (outer diameter, width, etc.) can be found in the manufacturer’s datasheet. For NU2307ECP, typical dimensions are:
- Bore diameter: 35 χιλ.
- Εξωτερική διάμετρος: 80 χιλ.
- Πλάτος: 31 χιλ.
7. Lubrication and Maintenance:
- Proper lubrication is essential for optimal performance and longevity. The bearing can be lubricated with grease or oil, depending on the application.
