De NU320EM cylindrical roller bearing is a specific type of bearing designed to handle high radial loads and moderate axial loads. Hier is een overzicht van de belangrijkste kenmerken en specificaties:
Belangrijkste kenmerken:
- Type: NU320EM
- NU 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, making it suitable for applications with thermal expansion.
- 320 is the size designation, indicating the bore diameter and overall dimensions.
- EM refers to the internal design and cage material. In this case, “EM” typically denotes a machined brass cage, which is robust and suitable for high-speed applications.
- Laadvermogen:
- 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:
- De “EM” suffix indicates a machined brass cage, which provides better strength, durability, and performance at high speeds compared to stamped steel or polymer cages.
- Toepassingen:
- Commonly used in heavy machinery, gearboxes, electric motors, pumps, and industrial equipment where high radial loads and moderate speeds are present.
Dimensies (Standard Metric):
- droeg diameter (d): 100 Mm
- Buitendiameter (D): 215 Mm
- Breedte (B): 47 Mm
- 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.
Installation and Maintenance:
- 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.
