Այն NU209EM գլանաձև գլանակիրների տեսակ է. Ահա դրա առանձնահատկությունների եւ առանձնահատկությունների խզումը:
1. Առանցքակալի տեսակը:
- ՉԻ: 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. Չափերը:
- Այն 209 in NU209EM refers to the bearing’s size according to the ISO standard.
- Հորատանցքի տրամագիծը (դ): 45 մմ
- Արտաքին տրամագիծը (Դ): 85 մմ
- Լայնությունը (Բ): 19 մմ
3. Suffix:
- ԷՄ: The suffix indicates specific design features or modifications:
- Ե: Optimized internal design for higher load capacity.
- M: Machined brass cage (ամուր փողային վանդակ), which provides better strength and durability compared to stamped steel cages.
4. Բեռի հզորությունը:
- 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. Ծրագրեր:
- NU-type cylindrical roller bearings are commonly used in applications where high radial loads and axial displacement need to be accommodated, such as:
- Electric motors
- Gearboxes
- Machine tools
- Pumps
- Industrial machinery
6. Քսում:
- Proper lubrication is essential for optimal performance. Grease or oil lubrication can be used depending on the operating conditions.
7. Mounting and Maintenance:
- Ensure proper mounting and alignment to avoid premature failure.
- Regular maintenance, including lubrication and monitoring for wear, is recommended.
