Si NU205 EM is a type of cylindrical roller bearing. Here’s a breakdown of its specifications and features:
1. Bearing Type:
- NU: Indicates the bearing type. NU refers to a cylindrical roller bearing with two fixed ribs on the outer ring and no ribs on the inner ring. This design allows the inner ring to move axially relative to the outer ring, making it suitable for applications with axial displacement.
2. Dimensi:
- 205: This number indicates the size of the bearing. For a 205 bantalan:
- Bore Diameter (d): 25 Mm
- Outer Diameter (D): 52 Mm
- Lebar (B): 15 Mm
3. Suffix:
- EM: The suffix provides additional information about the bearing’s design or internal features. In this case:
- E: Indicates an optimized internal design with increased load-carrying capacity.
- M: Indicates that the bearing is made of brass (copper alloy) cage, which is suitable for high-speed applications and offers better wear resistance.
4. Key Features:
- High Radial Load Capacity: Cylindrical roller bearings are designed to handle high radial loads.
- Axial Displacement: The NU design allows for axial displacement of the shaft relative to the housing, making it suitable for applications where thermal expansion or misalignment occurs.
- Brass Cage (M): The brass cage provides better durability and performance at high speeds compared to steel or polymer cages.
5. Applications:
- NU205 EM bearings are commonly used in:
- Electric motors
- Gearboxes
- Industrial machinery
- Pumps
- Conveyors
- Any application requiring high radial load capacity and axial displacement.
6. Lubrication:
- 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 to avoid misalignment.
- Regularly check and maintain lubrication to extend bearing life.
