The NJ2215ECP is a type of cylindrical roller bearing. Here’s a breakdown of its key features and specifications:
1. Bearing Type:
- NJ: This indicates the bearing type.
- NJ stands for a cylindrical roller bearing with a single rib on the outer ring and two ribs on the inner ring. It is designed to handle radial loads and limited axial loads in one direction.
2. Dimensions:
- The 2215 in the bearing code specifies its dimensions:
- Bore Diameter (D): 75 manm
- Dyamèt eksteryè (D): 130 manm
- Lajè (B): 31 manm
3. ECP Designation:
- EC: Stands for “Optimized Internal Design,” which means the bearing has a higher load-carrying capacity due to improved roller and raceway profiles.
- P: Indicates the bearing’s tolerance class.
- P6: High-precision tolerance class (better than standard).
4. Applications:
- Cylindrical roller bearings like the NJ2215ECP are commonly used in applications requiring high radial load capacity, such as:
- Gearboxes
- Electric motors
- Industrial machinery
- Pumps and compressors
5. Material and Lubrication:
- Typically made from high-quality bearing steel (e.g., SUJ2 or equivalent).
- Lubrication depends on the application but can include grease or oil.
6. Advantages:
- High radial load capacity.
- Suitable for high-speed applications.
- Can accommodate limited axial displacement.
If you need further details, such as load ratings, dynamic/static capacities, or specific application guidance, consult the manufacturer’s datasheet or technical documentation.
