די 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. די “2” indicates the series (light or medium duty), and “08” represents the bore diameter. פֿאַר מעטריק בערינגז, the bore diameter is calculated as 08 × 5 = 40 mm.
- 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. שליסל פֿעיִקייטן:
- טיפּ: Cylindrical roller bearing (NU type).
- נודנע דיאַמעטער: 40 mm.
- ויסווייניקסט דיאַמעטער: 80 mm.
- ברייט: 18 mm.
- מאַסע קאַפּאַציטעט: High radial load capacity due to the “E” פּלאַן.
- קאַגע: Machined brass cage (MI) for strength and durability.
- Axial Displacement: Allows axial displacement of the shaft relative to the housing.
3. אַפּפּליקאַטיאָנס:
- Suitable for applications with high radial loads and moderate axial displacement.
- Commonly used in:
- עלעקטריק מאָטאָרס.
- גירבאַקס.
- ינדוסטריאַל מאַשינערי.
- פּאַמפּס און קאַמפּרעסערז.
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.
