The Spherical Roller Bearing 23218 CC/W33 is a specific type of bearing designed to handle heavy radial and axial loads, particularly in applications where misalignment or shaft deflection may occur. Here’s a breakdown of its key features and specifications:
1. Leje Type: Spherical Roller Bearing
- Spherical roller bearings are self-aligning, meaning they can accommodate misalignment between the shaft and housing. This is due to their spherical outer ring raceway and barrel-shaped rollers.
2. Bearing Designation: 23218 CC/W33
- 23218: This is the bearing’s size designation.
- 2: Series (indicates the bearing’s dimensions and load capacity).
- 32: Bore diameter (in mm). For 23218, the bore diameter is 90 Mm.
- 18: Indicates the bearing’s internal design and dimensions.
- CC: Indicates the bearing’s internal design and cage type.
- CC: Two-piece brass cage, optimized for high-load applications and better lubrication retention.
- W33: Indicates a lubrication groove and three lubrication holes in the outer ring for improved lubrication.
3. Dimensioner:
- Bore Diameter (d): 90 Mm
- Outer Diameter (D): 160 Mm
- Bredde (B): 52.4 Mm
4. Load Capacity:
- Spherical roller bearings are designed to handle heavy radial and axial loads. The exact dynamic and static load ratings for the 23218 CC/W33 can be found in manufacturer catalogs (e.g., SKF, FAG, NSK, etc.).
5. Applications:
- Commonly used in heavy-duty applications such as:
- Gearkasser
- Mining equipment
- Paper mills
- Conveyors
- Pumps
- Wind turbines
6. Lubrication:
- The W33 suffix indicates the bearing has a lubrication groove and holes, making it suitable for applications requiring frequent relubrication.
7. Material:
- Typically made from high-quality chrome steel, but special materials (e.g., rustfrit stål) are available for corrosive environments.
8. Operating Conditions:
- Suitable for high-speed and high-temperature applications, depending on lubrication and sealing.
9. Mounting and Maintenance:
- Proper mounting and alignment are critical for optimal performance.
- Regular lubrication and maintenance are required to ensure longevity.
