ද NU312 සිලින්ඩරාකාර රෝලර් දරණ වර්ගයකි. Here’s a breakdown of its key features and specifications:
1. දරණ වර්ගය:
- නැත: This indicates the bearing type. In this case, නැත එයින් අදහස් වන්නේ එය පිටත වළල්ලේ ෆ්ලැන්ජ් දෙකක් සහ අභ්යන්තර වළල්ලේ ෆ්ලැන්ජ් නොමැති සිලින්ඩරාකාර රෝලර් දරණ බවයි. This design allows the inner ring to move axially relative to the outer ring, making it suitable for applications with axial displacement.
2. මාන:
- ද 312 in NU312 refers to the bearing’s size according to the ISO standard.
- Inner Diameter (ඈ): 60 මි.මී
- පිටත විෂ්කම්භය (ඩී): 130 මි.මී
- පළල (බී): 31 මි.මී
3. පැටවීමේ ධාරිතාව:
- Cylindrical roller bearings like the NU312 are designed to handle high radial loads. They are not suitable for axial loads unless combined with another bearing type.
- The dynamic and static load ratings depend on the manufacturer and specific design, but typical values are:
- ගතික පැටවුම් ශ්රේණිගත කිරීම (සී): ~108 kN
- ස්ථිතික පැටවුම් ශ්රේණිගත කිරීම (C0): ~102 kN
4. යෙදුම්:
- NU312 bearings are commonly used in applications where high radial loads and moderate speeds are present, ආදි:
- විදුලි මෝටර
- ගියර් පෙට්ටි
- කාර්මික යන්ත්රෝපකරණ
- පොම්ප
- Compressors
5. ද්රව්ය:
- Typically made from high-quality chrome steel (උදා., SAE 52100) for durability and wear resistance.
- Optional materials like stainless steel or special coatings may be available for corrosive or high-temperature environments.
6. කූඩුව:
- The cage (which separates the rollers) is usually made of steel, brass, or polyamide (plastic), depending on the application requirements.
7. ලිහිසි කිරීම:
- Proper lubrication is essential for optimal performance. Grease or oil lubrication can be used, depending on the operating conditions.
8. Mounting and Maintenance:
- NU312 bearings are typically mounted with an interference fit on the shaft and a loose fit in the housing.
- Regular maintenance, including lubrication and monitoring for wear, is necessary to ensure long service life.
