द NU209EM is a type of cylindrical roller bearing. Here’s a breakdown of its specifications and features:
1. असर प्रकार:
- होइन: Indicates the type of cylindrical roller bearing. NU bearings have two fixed ribs on the outer ring and no ribs on the inner ring, allowing the inner ring to move axially relative to the outer ring. This design is suitable for applications where axial displacement needs to be accommodated.
2. आयामहरू:
- द 209 in NU209EM refers to the bearing’s size according to the ISO standard.
- बोर व्यास (d): 45 mm
- बाहिरी व्यास (D): 85 mm
- चौडाइ (बि): 19 mm
3. प्रत्यय:
- EM: The suffix indicates specific design features or modifications:
- इ: उच्च लोड क्षमताको लागि अनुकूलित आन्तरिक डिजाइन.
- M: Machined brass cage (solid brass cage), which provides better strength and durability compared to stamped steel cages.
4. लोड क्षमता:
- Cylindrical roller bearings like the NU209EM are designed to handle high radial loads but are not suitable for axial loads (except for slight axial guidance).
5. अनुप्रयोगहरू:
- NU-type cylindrical roller bearings are commonly used in applications where high radial loads and axial displacement need to be accommodated, जस्तै:
- इलेक्ट्रिक मोटर्स
- गियरबक्सहरू
- मेसिन उपकरणहरू
- पम्पहरू
- औद्योगिक मेसिनरी
6. स्नेहन:
- Proper lubrication is essential for optimal performance. Grease or oil lubrication can be used depending on the operating conditions.
7. माउन्टिङ र मर्मतसम्भार:
- Ensure proper mounting and alignment to avoid premature failure.
- नियमित मर्मतसम्भार, including lubrication and monitoring for wear, is recommended.
