The NJ307ECP is a type of cylindrical roller bearing. 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 flange on the outer ring and a double flange on the inner ring. This design allows for axial displacement in one direction.
2. Dimenzije:
- 30: The first two digits (30) represent the bore diameter. To calculate the bore diameter in millimeters, multiply by 5:
30×5=150 mm. - 07: The next two digits (07) represent the series, indicating the width and outer diameter of the bearing. This is a medium series bearing.
3. Suffixes:
- EC: This suffix indicates an optimized internal design with more and/or larger rollers, providing higher load-carrying capacity.
- P: This suffix indicates that the bearing is made of high-quality steel (typically higher purity) and has improved fatigue life.
4. Ključne karakteristike:
- High Radial Load Capacity: Cylindrical roller bearings are designed to handle high radial loads.
- Axial Displacement: The NJ design allows for axial displacement in one direction, making it suitable for applications where thermal expansion or shaft misalignment occurs.
- Precision and Durability: The “ECP” designation ensures high precision and durability, making it suitable for demanding applications.
5. Aplikacije:
- Commonly used in industrial machinery, mjenjači, electric motors, and other applications requiring high radial load capacity and moderate axial displacement.
6. Lubrication and Maintenance:
- Proper lubrication is essential for optimal performance. Grease or oil lubrication can be used depending on the application.
- Regular maintenance and monitoring are recommended to ensure long service life.
