The NJ2214ECP is a specific type of cylindrical roller bearing. Here’s a breakdown of its key features and specifications:
1. Bearing Type:
- NJ: This indicates the bearing type.
- NJ stands for a cylindrical roller bearing with a single rib on the outer ring and a double rib on the inner ring. This design allows for axial displacement in one direction.
2. Dimenzije:
- 2214: This refers to the bearing’s size.
- 22: Bore diameter = 110 Mm (22 x 5 = 110 Mm, as the last two digits are multiplied by 5 for bore sizes ≥ 20 Mm).
- 14: Outer diameter = 140 Mm.
- The width (thickness) of the bearing is typically around 33 Mm (this may vary slightly depending on the manufacturer).
3. ECP:
- EC: Enhanced Capacity design. This means the bearing has optimized internal geometry (e.g., roller profile, cage design) to handle higher radial loads and provide better performance.
- P: Polyamide (nylon) cage. This lightweight cage material reduces friction and is suitable for high-speed applications.
4. Applications:
- Cylindrical roller bearings like the NJ2214ECP are commonly used in applications requiring high radial load capacity and moderate axial load capacity in one direction. Examples include:
- Gearboxes
- Electric motors
- Industrial machinery
- Pumps and compressors
5. Key Features:
- High radial load capacity
- Moderate axial load capacity in one direction
- Suitable for high-speed operations due to the polyamide cage
- Robust design for heavy-duty applications
6. Equivalent Bearings:
- Depending on the manufacturer, the NJ2214ECP may have equivalents or cross-references, such as:
- SKF: NJ2214ECP
- FAG: NJ2214E.TVP2
- NSK: NJ2214
