Дар NU209EM як навъи подшипникҳои силиндрӣ мебошад. Дар ин ҷо тавсифи мушаххасот ва хусусиятҳои он:
1. Навъи подшипник:
- НЕ: 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. Андозаҳо:
- Дар 209 in NU209EM refers to the bearing’s size according to the ISO standard.
- Диаметри сӯрох (г): 45 мм
- Диаметри беруна (Д): 85 мм
- Васеъ (Б): 19 мм
3. Suffix:
- ЭМ: The suffix indicates specific design features or modifications:
- Э: Optimized internal design for higher load capacity.
- M: Machined brass cage (қафаси сахти биринҷӣ), which provides better strength and durability compared to stamped steel cages.
4. Load Capacity:
- 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. Барномаҳо:
- NU-type cylindrical roller bearings are commonly used in applications where high radial loads and axial displacement need to be accommodated, such as:
- Моторхои электрики
- Gearboxes
- Machine tools
- Насосҳо
- Мошинҳои саноатӣ
6. Молидани:
- 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.
Агар ба шумо тафсилоти бештар лозим бошад, such as dynamic/static load ratings or specific operating conditions, consult the manufacturer’s datasheet or technical documentation.
