جي NU312 سلنڈر رولر بيئرنگ جو هڪ قسم آهي. هتي هن جي اهم خاصيتن ۽ وضاحتن جي خرابي آهي:
1. برداشت جو قسم:
- NU: اهو ظاهر ڪري ٿو بيئرنگ جو قسم. In this case, NU means it is a cylindrical roller bearing with two flanges on the outer ring and no flanges on the inner ring. This design allows the inner ring to move axially relative to the outer ring, making it suitable for applications with axial displacement.
2. طول و عرض:
- جي 312 in NU312 refers to the bearing’s size according to the ISO standard.
- اندروني قطر (ڊي): 60 ايم ايم
- ٻاهرين قطر (ڊي): 130 ايم ايم
- وني ترقي (ب): 31 ايم ايم
3. لوڊشيڊنگ جي گنجائش:
- 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:
- متحرڪ لوڊ ريٽنگ (چار): ~108 kN
- جامد لوڊ ريٽنگ (C0): ~102 kN
4. درخواستون:
- NU312 bearings are commonly used in applications where high radial loads and moderate speeds are present, such as:
- اليڪٽرڪ موٽرز
- Gearboxes
- صنعتي مشينري
- پمپس
- Compressors
5. مواد:
- عام طور تي اعلي معيار جي ڪروم اسٽيل مان ٺهيل آهي (مثال طور., 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. Cage:
- The cage (which separates the rollers) is usually made of steel, brass, or polyamide (plastic), depending on the application requirements.
7. لبنان:
- Proper lubrication is essential for optimal performance. Grease or oil lubrication can be used, آپريٽنگ حالتن تي منحصر آهي.
8. چڙهڻ ۽ سار سنڀال:
- NU312 bearings are typically mounted with an interference fit on the shaft and a loose fit in the housing.
- باقاعده بحالي, including lubrication and monitoring for wear, is necessary to ensure long service life.
