ද NJ207E සිලින්ඩරාකාර රෝලර් දරණ වර්ගයකි. මෙන්න එහි පිරිවිතර සහ විශේෂාංග බිඳවැටීමක්:
1. ටයිප් කරන්න:
- 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. ද “NJ” design allows for axial displacement in one direction.
2. මාන:
- බෝර විෂ්කම්භය (ඈ): 35 මි.මී
- පිටත විෂ්කම්භය (ඩී): 72 මි.මී
- පළල (බී): 17 මි.මී
These dimensions are standardized for the NJ207E bearing.
3. කූඩුව:
- The bearing typically uses a steel or brass cage to separate the rollers, ensuring smooth operation and reducing friction.
4. පැටවීමේ ධාරිතාව:
- 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:
- ද “ඊ” in NJ207E indicates an optimized internal design with increased load-carrying capacity. This is achieved through improved roller and raceway profiles.
6. යෙදුම්:
- Cylindrical roller bearings are commonly used in applications requiring high radial load capacity, ආදි:
- විදුලි මෝටර
- ගියර් පෙට්ටි
- Machine tools
- Automotive transmissions
7. ලිහිසි කිරීම:
- Proper lubrication is essential for optimal performance. Grease or oil lubrication can be used depending on the application and operating conditions.
8. සවි කිරීම:
- 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. සමාන ෙබයාරිං:
- Other bearings with similar dimensions and load capacities include:
- NJ207
- NJ207ECP
- NJ207ECJ
