द NJ207E is a type of cylindrical roller bearing. Here’s a breakdown of its specifications and features:
1. टाइप गर्नुहोस्:
- 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. द “NJ” design allows for axial displacement in one direction.
2. आयामहरू:
- बोर व्यास (d): 35 mm
- बाहिरी व्यास (D): 72 mm
- चौडाइ (बि): 17 mm
These dimensions are standardized for the NJ207E bearing.
3. पिंजरा:
- The bearing typically uses a steel or brass cage to separate the rollers, ensuring smooth operation and reducing friction.
4. लोड क्षमता:
- 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:
- द “इ” in NJ207E indicates an optimized internal design with increased load-carrying capacity. This is achieved through improved roller and raceway profiles.
6. अनुप्रयोगहरू:
- Cylindrical roller bearings are commonly used in applications requiring high radial load capacity, जस्तै:
- इलेक्ट्रिक मोटर्स
- गियरबक्सहरू
- मेसिन उपकरणहरू
- मोटर वाहन प्रसारण
7. स्नेहन:
- Proper lubrication is essential for optimal performance. Grease or oil lubrication can be used depending on the application and operating conditions.
8. माउन्ट गर्दै:
- 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. बराबर बियरिंग्स:
- Other bearings with similar dimensions and load capacities include:
- NJ207
- NJ207ECP
- NJ207ECJ
