'Ōlelo Nu313 eCJ heʻano hiʻohiʻona o ka cylindrical roller e hāpai. Eia kahi wāwahi o kāna mau hiʻohiʻona kiʻekiʻe a me nā kiko'ī:
1. Ke nānā nei i keʻano:
- NU313: This indicates that it is a cylindrical roller bearing with no ribs on the outer ring and two ribs on the inner ring. 'Ōlelo “AOLE” design allows the inner ring to be separable from the outer ring and the roller cage assembly, which is useful for certain mounting and dismounting applications.
2. Anana:
- 'Ōlelo “313” in the bearing designation refers to its size according to ISO standards.
- ʻO ka diameter Inner (D): 65 mm
- ʻO ka lole o waho (D): 140 mm
- Laulā (Na B): 33 mm
3. ECJ Designation:
- ECJ: Ke kū nei kēia “Enhanced Capacity Journal” Oole “Enhanced Capacity Joint.” It typically refers to a bearing with an optimized internal design, such as a larger number of rollers or a modified roller profile, to increase the load-carrying capacity and improve performance.
4. Nā mea hoʻouka nui:
- ʻO ka helu waihona kālā Dynamic (C): This is the load that the bearing can withstand for a certain number of revolutions before fatigue occurs. For NU313 ECJ, this is typically around 170 k kn.
- ʻO ka helu ukana Static (C0): This is the maximum load the bearing can handle without permanent deformation. For NU313 ECJ, this is usually around 190 k kn.
5. Hoʻoholo wikiwiki:
- Hoʻolālā ʻia ka bearing e hana i nā wikiwiki kiʻekiʻe, with a limiting speed (depending on lubrication and cooling conditions) maʻamau a puni 6000 rpm for oil lubrication and slightly lower for grease lubrication.
6. Noi:
- Cylindrical roller bearings like the NU313 ECJ are commonly used in applications where high radial loads are present, e like me ka in:
- ʻO nā mokuahi uila
- Nā Hāʻewa
- Nā mīkini mīkini
- Pumps
- Nā mea kaomi
7. Waiwai:
- The bearing is usually made from high-quality bearing steel, such as SAE 52100, which is heat-treated for durability and wear resistance.
8. Lubrication:
- Hiki ke hoʻopauʻia ka bound i ka lubricated me ka aila a iʻole aila, ma muli o nā koi noi. Proper lubrication is crucial for maximizing the bearing’s lifespan and performance.
9. Loko:
- ʻO ka pā, ka mea e paa ai na wili, is typically made from steel or brass, depending on the specific variant and application requirements.
10. Ke kau ʻana a me ka mālama ʻana:
- The NU313 ECJ bearing is designed for easy mounting and dismounting, especially in applications where the inner ring needs to be mounted separately from the outer ring.
- Mālama mau, including proper lubrication and monitoring for wear, is essential to ensure long service life.
Hōʻuluʻulu manaʻo:
'Ōlelo Nu313 eCJ cylindrical roller bearing is a high-capacity, high-performance bearing designed for applications with significant radial loads. Its enhanced design allows for greater load-carrying capacity and improved operational efficiency, making it suitable for a wide range of industrial applications.
