3. Setup and Installation
Proper installation is crucial for the longevity and performance of your SKF 6002 bearing. Follow these general guidelines:
- Preparation: Ensure the shaft and housing seats are clean, free from burrs, and within specified tolerances.
- Lubrication: Apply a thin layer of compatible grease to the bearing seats before mounting. The SKF 6002 bearing is typically pre-lubricated, but additional lubrication may be required depending on the application.
- Mounting:
- For press fit applications, use a bearing heater or induction heater to expand the inner ring, making installation easier and preventing damage.
- Apply mounting force only to the ring that is being fitted (e.g., inner ring for shaft fit, outer ring for housing fit). Never apply force through the rolling elements.
- Use appropriate mounting tools (e.g., bearing fitting tools, hydraulic presses) to ensure even pressure and prevent misalignment.
- Inspection: After mounting, rotate the shaft or housing to ensure smooth operation and no binding.
Note: For specific application requirements, consult detailed engineering guidelines or an SKF representative.
4. Operating Considerations
To maximize the lifespan and efficiency of your SKF 6002 bearing, consider the following during operation:
- Load Capacity: Ensure that the applied radial and axial loads do not exceed the bearing's dynamic and static load ratings. Overloading can lead to premature failure.
- Speed Limits: Operate the bearing within its specified speed limits. Exceeding these limits can cause excessive heat generation and damage.
- Temperature: Monitor operating temperature. Excessive heat can degrade lubricant and bearing material. Ensure proper heat dissipation.
- Vibration and Noise: Unusual vibration or noise during operation may indicate an issue. Investigate immediately.
- Contamination: Protect the bearing from contaminants such as dust, dirt, and moisture, which can cause wear and corrosion.
5. Maintenance
Regular maintenance helps ensure optimal performance and extends the service life of your SKF 6002 bearing:
- Lubrication: While deep groove ball bearings are often sealed and pre-lubricated for life, open or shielded versions may require periodic re-lubrication with a compatible grease. Follow manufacturer's recommendations for re-lubrication intervals and grease type.
- Cleaning: Keep the area around the bearing clean to prevent ingress of contaminants.
- Inspection: Periodically inspect the bearing for signs of wear, corrosion, or damage. Check for unusual noise, vibration, or excessive heat.
- Storage: Store spare bearings in their original packaging in a cool, dry, and vibration-free environment to prevent damage and corrosion.
6. Troubleshooting
This section provides guidance on common issues that may arise with ball bearings:
| Problem | Possible Cause(s) | Solution(s) |
|---|---|---|
| Excessive Noise/Vibration | Lack of lubrication, contamination, misalignment, damage to bearing components, improper fit. | Check lubrication, clean bearing area, inspect for damage/misalignment, ensure correct fit. Replace if damaged. |
| Overheating | Excessive speed, insufficient lubrication, overloading, improper internal clearance, misalignment. | Reduce speed/load, check lubrication, verify alignment, ensure proper bearing selection for application. |
| Premature Failure | Contamination, improper installation, overloading, inadequate lubrication, corrosion. | Review installation procedures, ensure proper sealing, maintain lubrication, verify load calculations. |
