Та NJ207E is a type of cylindrical roller bearing. Here’s a breakdown of its specifications and features:
1. Басу:
- NJ: This indicates the bearing is a cylindrical roller bearing with a single rib on the outer ring and two ribs on the inner ring. Та “NJ” design allows for axial displacement in one direction.
2. Өлшемдер:
- Саңылау диаметрі (г): 35 мм
- Сыртқы диаметрі (D): 72 мм
- Ені (Б): 17 мм
These dimensions are standardized for the NJ207E bearing.
3. Тор:
- The bearing typically uses a steel or brass cage to separate the rollers, ensuring smooth operation and reducing friction.
4. Жүктеме сыйымдылығы:
- Cylindrical roller bearings like the NJ207E are designed to handle high radial loads. They are not suitable for axial loads unless combined with another bearing.
5. E-Suffix:
- Та “Е е” in NJ207E indicates an optimized internal design with increased load-carrying capacity. This is achieved through improved roller and raceway profiles.
6. Қолданбалар:
- Cylindrical roller bearings are commonly used in applications requiring high radial load capacity, сияқты:
- Электр қозғалтқыштары
- Беріліс қораптары
- Machine tools
- Automotive transmissions
7. Майлау:
- Proper lubrication is essential for optimal performance. Grease or oil lubrication can be used depending on the application and operating conditions.
8. Орнату:
- The NJ207E bearing is typically mounted with an interference fit on the shaft and a loose fit in the housing. Proper installation is crucial to prevent misalignment and premature failure.
9. Эквивалентті подшипниктер:
- Other bearings with similar dimensions and load capacities include:
- NJ207
- NJ207ECP
- NJ207ECJ
