دی NJ210ECP 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 is a cylindrical roller bearing with a single rib on the outer ring and two ribs on the inner ring. دی “NJ” design allows for axial displacement in one direction.
2. ابعاد:
- 210: This refers to the bearing’s size designation.
- Bore Diameter (d): 50 ملی میٹر
- Outer Diameter (D): 90 ملی میٹر
- چوڑائی (B): 20 ملی میٹر
3. ECP Designation:
- EC: Stands for “Optimized Internal Design,” which means the bearing has a higher load capacity due to an increased number of rollers and improved roller guidance.
- P: Indicates the bearing is made of high-quality, heat-treated steel (typically SUJ2 or equivalent) for enhanced durability and performance.
4. Load Capacity:
- High radial load capacity due to the cylindrical roller design.
- Moderate axial load capacity in one direction (due to the NJ design).
5. Applications:
- Commonly used in applications requiring high radial loads and moderate axial loads, such as:
- Gearboxes
- Electric motors
- Industrial machinery
- Automotive components
6. Lubrication:
- Typically lubricated with grease or oil, depending on the application and operating conditions.
7. Cage:
- Usually made of steel or brass, depending on the manufacturer and specific model.
