이 NJ211ECP is a type of cylindrical roller bearing, commonly used in various industrial applications. Here’s a breakdown of its specifications and features:
1. Bearing Type:
- NJ: This indicates the bearing type. “NJ” refers to a cylindrical roller bearing with a single rib on the outer ring and a double rib on the inner ring. This design allows for axial displacement in one direction.
2. 차원:
- 211: This number specifies the size of the bearing.
- Bore Diameter (d): 55 밀리미터
- Outer Diameter (D): 100 밀리미터
- Width (B): 21 밀리미터
3. ECP Designation:
- EC: Stands for “Enhanced Capacity.” This means the bearing has an optimized internal design with more or larger rollers, increasing its load-carrying capacity.
- P: Indicates the use of glass fiber reinforced polyamide (PA66) as the cage material. This cage material is lightweight, durable, and suitable for high-speed applications.
4. Key Features:
- High radial load capacity due to the cylindrical roller design.
- Suitable for axial loads in one direction.
- Enhanced capacity (EC) design for higher performance.
- Polyamide cage (P) for reduced friction and high-speed operation.
5. Applications:
- Commonly used in gearboxes, electric motors, pumps, and other machinery where high radial loads and moderate axial loads are present.
6. Lubrication:
- Requires proper lubrication to ensure smooth operation and longevity. Grease or oil lubrication can be used depending on the application.
If you need further details, such as load ratings, speed limits, or installation instructions, consult the manufacturer’s datasheet or technical documentation.
