The N316ECM is a specific type of cylindrical roller bearing. Here’s a breakdown of its key features and specifications:
1. Bearing Type:
- Cylindrical Roller Bearing: This type of bearing is designed to handle high radial loads and moderate axial loads. The rollers are cylindrical in shape, providing a larger contact area with the raceways, which allows for high load capacity and rigidity.
2. Bearing Designation:
- N316ECM:
- N: Indicates that the bearing has a snap ring groove on the outer ring. This allows for axial positioning of the bearing in the housing.
- 316: Refers to the bearing size and dimensions. The “3” typically indicates a medium series bearing, and “16” refers to the bore diameter (16 x 5 = 80 mm).
- EC: Stands for “Enhanced Capacity,” which means the bearing has an optimized internal design (e.g., modified roller and raceway profiles) to increase load capacity and reduce stress.
- M: Indicates that the bearing is made from high-quality bearing steel with improved durability and performance.
3. Dimensions:
- Bore Diameter (d): 80 mm
- Outer Diameter (D): 170 mm
- Width (B): 39 mm
4. Load Ratings:
- Dynamic Load Rating (C): The maximum load the bearing can handle while rotating. For N316ECM, this is typically around 300 kN (exact value depends on the manufacturer).
- Static Load Rating (C₀): The maximum load the bearing can handle while stationary. For N316ECM, this is typically around 340 kN.
5. Speed Ratings:
- Limiting Speed: The maximum rotational speed the bearing can handle without failing. This depends on lubrication and operating conditions but is typically around 4000 rpm for grease lubrication and 5000 rpm for oil lubrication.
6. Applications:
- Cylindrical roller bearings like the N316ECM are commonly used in applications requiring high radial load capacity and moderate axial load capacity, such as:
- Gearboxes
- Electric motors
- Pumps
- Industrial machinery
- Wind turbines
7. Advantages:
- High radial load capacity
- Moderate axial load capacity
- Suitable for high-speed applications
- Enhanced internal design for longer service life
8. Manufacturer-Specific Variations:
- Different manufacturers may have slight variations in dimensions, load ratings, and materials. Always refer to the manufacturer’s datasheet for precise information.
