The NUP2204ECP is a specific type of cylindrical roller bearing. Here’s a breakdown of its designation and key features:
1. Bearing Type: Cylindrical Roller Bearing
- Cylindrical roller bearings are designed to handle high radial loads and moderate axial loads. They have high rigidity and are suitable for high-speed applications.
2. NUP2204ECP Designation Breakdown
- NUP: This indicates the design and type of the bearing.
- NUP means the bearing has a solid outer ring, two fixed ribs, and a loose rib on the inner ring. This design allows for axial displacement of the shaft in both directions.
- 22: This refers to the series. The “22” series indicates a medium width and diameter for the bearing.
- 04: This indicates the bore diameter. The bore diameter is calculated as 04 × 5 = 20 milimetr.
- EC: This stands for “Enhanced Capacity,” meaning the bearing has an optimized internal design (e.g., modified roller profiles) to increase load capacity and reduce stress.
- P: This indicates the bearing is made of high-quality steel (typically SUJ2 or equivalent) and has improved durability and performance.
3. Key Features
- High Radial Load Capacity: Suitable for applications with heavy radial loads.
- Moderate Axial Load Capacity: Can handle some axial loads due to the NUP design.
- High-Speed Capability: Suitable for high-speed applications.
- Precision Engineering: The ECP designation ensures high precision and durability.
4. Applications
- Commonly used in:
- Electric motors
- Gearboxes
- Industrial machinery
- Pumps and compressors
- Automotive applications
5. Dimensions (Typical for NUP2204ECP)
- Bore Diameter (d): 20 milimetr
- Outer Diameter (D): 47 milimetr
- Šířka (B): 18 milimetr
6. Lubrication and Maintenance
- Proper lubrication is essential for optimal performance and longevity. Grease or oil lubrication can be used depending on the application.
