1. Introduction
This manual provides essential information for the proper handling, installation, operation, and maintenance of the SKF Sweden 24152 CC W33 Spherical Roller Bearing. Adhering to these guidelines will help ensure optimal performance, longevity, and safety of the bearing in its intended application. This bearing is designed for heavy-duty applications and can accommodate angular misalignment.
2. Product Overview
The SKF 24152 CC W33 is a high-quality spherical roller bearing manufactured in Sweden. It features a tapered bore (1:30) and a sheet steel cage. The 'CC' designation indicates two rows of symmetrical rollers, a common spherical outer ring raceway, and two inner ring raceways inclined at an angle to the bearing axis. The 'W33' indicates a lubrication groove and three lubrication holes in the outer ring, facilitating effective relubrication.

3. Installation (Setup)
Proper installation is critical for the performance and lifespan of the bearing. It is highly recommended that installation be performed by qualified personnel using appropriate tools and techniques.
- Preparation: Ensure the shaft and housing seats are clean, free from burrs, and within specified tolerances.
- Mounting: For bearings with a tapered bore, mounting typically involves driving the bearing onto a tapered shaft or adapter sleeve. This requires careful control of the interference fit to achieve the correct radial internal clearance. Specialized hydraulic tools or heating methods may be necessary.
- Lubrication: Apply a suitable lubricant to the bearing and mating surfaces before mounting to prevent damage and aid installation.
- Alignment: Verify proper alignment of the bearing with its mating components to prevent premature wear.
- Sealing: Ensure appropriate seals are in place to protect the bearing from contaminants and retain lubricant.
Refer to SKF's general mounting instructions for spherical roller bearings for detailed procedures.
4. Operation
Once installed, the bearing is designed for continuous operation within its specified parameters. Key operational considerations include:
- Load Capacity: Do not exceed the bearing's dynamic and static load ratings.
- Speed Limits: Operate within the recommended speed limits to prevent excessive heat generation and wear.
- Temperature Range: The bearing is designed to operate within a temperature range of -30 to +200 °C. Monitor operating temperature to ensure it remains within this range. Excessive heat can degrade lubricant and bearing materials.
- Vibration and Noise: Monitor for unusual vibration or noise, which can indicate potential issues.
5. Maintenance
Regular maintenance is essential for extending the service life of the spherical roller bearing.
- Lubrication: The W33 feature (lubrication groove and holes) allows for effective relubrication. Follow the equipment manufacturer's recommendations for lubricant type, quantity, and relubrication intervals. Use clean, high-quality grease or oil.
- Inspection: Periodically inspect the bearing and surrounding components for signs of wear, corrosion, or damage. Check seals for integrity.
- Cleaning: Keep the bearing environment clean to prevent contamination, which is a major cause of premature bearing failure.
- Storage: If storing spare bearings, keep them in their original packaging in a dry, vibration-free environment to prevent damage and corrosion.
6. Troubleshooting
This section provides general guidance for common bearing issues. For specific problems, consult a bearing specialist or the equipment manufacturer.
| Symptom | Possible Cause | Action |
|---|---|---|
| Excessive Noise/Vibration | Inadequate lubrication, contamination, misalignment, damage to raceways or rollers, incorrect fit. | Check lubrication, inspect for contamination, verify alignment, inspect bearing for damage. |
| Overheating | Insufficient lubrication, excessive load, too tight fit, high speed, inadequate cooling. | Check lubrication, reduce load if possible, verify fit, ensure proper cooling. |
| Premature Wear | Contamination, insufficient lubrication, misalignment, excessive load, vibration. | Improve sealing, ensure proper lubrication, correct alignment, verify load. |
