Дар NU320EM cylindrical roller bearing is a specific type of bearing designed to handle high radial loads and moderate axial loads. Here’s a breakdown of its key features and specifications:
Хусусиятҳои асосӣ:
- Навъи: NU320EM
- НЕ indicates the bearing type: a cylindrical roller bearing with two flanges on the outer ring and no flanges on the inner ring. This design allows for free axial displacement of the shaft relative to the housing, онро барои барномаҳо бо тавсеаи гармӣ мувофиқ месозад.
- 320 is the size designation, indicating the bore diameter and overall dimensions.
- ЭМ refers to the internal design and cage material. In this case, “ЭМ” typically denotes a machined brass cage, which is robust and suitable for high-speed applications.
- Load Capacity:
- High radial load capacity due to the cylindrical rollers.
- Limited axial load capacity (can only handle axial loads in one direction or as a guide bearing).
- Cage Material:
- Дар “ЭМ” suffix indicates a machined brass cage, which provides better strength, durability, and performance at high speeds compared to stamped steel or polymer cages.
- Барномаҳо:
- Commonly used in heavy machinery, қуттиҳои редуктор, electric motors, насосхо, and industrial equipment where high radial loads and moderate speeds are present.
Андозаҳо (Standard Metric):
- Диаметри сӯрох (г): 100 мм
- Диаметри беруна (Д): 215 мм
- Васеъ (Б): 47 мм
- Roller Dimensions: Specific to the bearing design (exact dimensions can be found in manufacturer catalogs).
Advantages:
- High radial load capacity.
- Suitable for high-speed applications due to the brass cage.
- Allows for axial displacement of the shaft, accommodating thermal expansion.
Насб ва нигоҳдорӣ:
- Proper mounting and alignment are critical to ensure optimal performance.
- Regular lubrication is necessary to reduce friction and wear.
- Monitor for signs of wear, such as noise or vibration, to prevent failure.
Manufacturer Variations:
- Different manufacturers may have slight variations in tolerances, internal clearances, or surface finishes. Always refer to the manufacturer’s datasheet for precise details.
