The NJ211ECP is a type of cylindrical roller bearing, commonly used in various industrial applications. Here’s a breakdown of its specifications and features:
1. Mataqali iSema:
- 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. Na kena levu:
- 211: This number specifies the size of the bearing.
- Bore Diameter (d): 55 mm
- Outer Diameter (D): 100 mm
- Rabailevu (B): 21 mm
3. ECP Designation:
- EC: E tutaka na “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. iVolakerekere:
- Commonly used in gearboxes, electric motors, pamu, 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.
