جي N317 ECM is a specific type of cylindrical roller bearing. هتي هن جي اهم خاصيتن ۽ وضاحتن جي خرابي آهي:
1. برداشت جو قسم: سلنڈر رولر بيئرنگ
- Cylindrical roller bearings are designed to handle high radial loads and moderate axial loads. They have high rigidity and are suitable for high-speed applications.
2. Bearing Designation: N317 ECM
- N: Indicates the bearing type. In this case, “N” refers to a cylindrical roller bearing with no flanges on the outer ring, allowing the inner ring and rollers to be displaced axially.
- 317: Represents the size and dimensions of the bearing. جي “3” indicates a medium series, and “17” refers to the bore diameter (17 x 5 = 85 ايم ايم).
- ECM: لاء بيٺو آهي Enhanced Capacity Model. This indicates that the bearing has an optimized internal design, such as improved roller profiles and surface finishes, to increase load-carrying capacity and reduce stress.
3. طول و عرض:
- بور جو قطر (ڊي): 85 ايم ايم
- ٻاهرين قطر (ڊي): 180 ايم ايم
- وني ترقي (ب): 41 ايم ايم
4. Load Ratings:
- متحرڪ لوڊ ريٽنگ (چار): The maximum load the bearing can handle while rotating. For N317 ECM, this is typically around 220 kN (exact value depends on the manufacturer).
- جامد لوڊ ريٽنگ (C0): The maximum load the bearing can handle while stationary. For N317 ECM, this is typically around 240 kN.
5. Speed Ratings:
- رفتار کي محدود ڪرڻ: The maximum rotational speed the bearing can handle. For N317 ECM, this is typically around 4000 rpm for grease lubrication and 5000 rpm for oil lubrication.
6. درخواستون:
- Cylindrical roller bearings like the N317 ECM are commonly used in:
- Industrial gearboxes
- اليڪٽرڪ موٽرز
- پمپس
- Compressors
- مشيني اوزار
- Wind turbines
7. Advantages of ECM Design:
- Higher load-carrying capacity
- Reduced stress on rollers and raceways
- Improved fatigue life
- Better performance under heavy loads and high speeds
8. Manufacturer-Specific Variations:
- Different manufacturers (مثال طور., SKF, NSK, Timken) may have slight variations in dimensions, load ratings, and tolerances. Always refer to the manufacturer’s datasheet for precise details.
