The NJ205ECP cylindrical roller bearing is a specific type of rolling-element bearing designed to handle high radial loads and moderate axial loads. Here’s a breakdown of its key features and specifications:
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 two ribs on the inner ring. This design allows the bearing to accommodate axial displacement in one direction.
2. มิติ:
- The “205” in the bearing code specifies its dimensions according to ISO standards:
- Bore Diameter (d): 25 มิลลิเมตร
- Outer Diameter (D): 52 มิลลิเมตร
- ความกว้าง (B): 15 มิลลิเมตร
3. ECP Designation:
- EC: Stands for “Enhanced Capacity.” This means the bearing has an optimized internal design with more and/or larger rollers, increasing its load-carrying capacity.
- P: Indicates that the bearing is made of high-quality, heat-treated steel (typically SUJ2 or equivalent) and is designed for high-performance applications.
4. Features:
- High radial load capacity.
- Can accommodate moderate axial loads in one direction.
- Suitable for high-speed applications due to its precision design.
- Often used in applications like gearboxes, electric motors, and industrial machinery.
5. Cage Type:
- The cage (which holds the rollers in place) is typically made of pressed steel or brass, depending on the manufacturer and application requirements.
6. Lubrication:
- These bearings are usually lubricated with grease or oil, depending on the operating conditions.
7. Applications:
- Commonly used in:
- Automotive transmissions
- Industrial gearboxes
- Electric motors
- Pumps and compressors
