이 NU208E.MI is a specific type of cylindrical roller bearing. Here’s a breakdown of its designation and features:
1. NU208E.MI Breakdown:
- NU: Indicates the bearing type. “NU” means it is a cylindrical roller bearing with two flanges on the outer ring and no flanges 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.
- 208: Refers to the bearing size. 이 “2” indicates the series (light or medium duty), and “08” represents the bore diameter. For metric bearings, the bore diameter is calculated as 08 × 5 = 40 밀리미터.
- E: Indicates an optimized internal design with a larger roller set, providing higher load-carrying capacity compared to standard designs.
- MI: Specifies the bearing’s cage material and design. “MI” typically means the cage is made of machined brass, which is durable and suitable for high-speed or high-temperature applications.
2. Key Features:
- 형: Cylindrical roller bearing (NU type).
- Bore Diameter: 40 밀리미터.
- Outer Diameter: 80 밀리미터.
- Width: 18 밀리미터.
- Load Capacity: High radial load capacity due to the “E” design.
- Cage: Machined brass cage (MI) for strength and durability.
- Axial Displacement: Allows axial displacement of the shaft relative to the housing.
3. Applications:
- Suitable for applications with high radial loads and moderate axial displacement.
- Commonly used in:
- Electric motors.
- Gearboxes.
- Industrial machinery.
- Pumps and compressors.
4. Advantages:
- High radial load capacity.
- Accommodates axial displacement.
- Durable brass cage for high-speed or high-temperature environments.
- Long service life with proper lubrication.
5. Maintenance:
- Ensure proper lubrication with grease or oil suitable for the operating conditions.
- Regularly check for wear, misalignment, or contamination.
