The NJ307ECP is a type of cylindrical roller bearing. Here’s a breakdown of its specifications and features:
1. Leje 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. Dimensioner:
- 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. Key Features:
- 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. Applications:
- Commonly used in industrial machinery, gearboxes, Elektromotorer, 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.
If you need further details, such as load ratings, exact dimensions, or specific application guidance, consult the manufacturer’s datasheet or a bearing supplier.
