Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your SKF seal. Always refer to the specific equipment manufacturer's guidelines for seal replacement procedures.
General Installation Steps:
- Preparation: Ensure the shaft and bore surfaces are clean, free from burrs, scratches, or any foreign particles. Lubricate the seal lip and the shaft with the system's operating fluid or a compatible lubricant before installation.
- Alignment: Carefully align the seal with the bore. Avoid tilting the seal during insertion.
- Pressing: Use an appropriate installation tool that applies even pressure around the outer diameter of the seal. Do not use sharp objects or hammers directly on the seal. Press the seal squarely into the bore until it is fully seated.
- Inspection: After installation, visually inspect the seal to ensure it is not damaged, twisted, or improperly seated.
Note: Incorrect installation can lead to premature seal failure and system leakage. If unsure, consult a qualified technician.
Operating Conditions
The SKF 8860 seal is designed to perform reliably under specific operating conditions. Adhering to these conditions will ensure maximum seal life and efficiency.
- Temperature Range: Operate within the specified temperature limits for the seal's material (Rubber).
- Pressure: Ensure system pressure does not exceed the seal's design limits.
- Fluid Compatibility: Use only fluids compatible with the seal's rubber material.
- Shaft Surface Finish: Maintain the recommended shaft surface finish for optimal sealing and reduced wear.
Maintenance
SKF seals are designed for long-term reliability with minimal maintenance. However, periodic inspection of the seal and surrounding components is recommended as part of a comprehensive maintenance program.
- Visual Inspection: Regularly check for signs of leakage, cracking, hardening, or excessive wear on the seal.
- Lubrication: Ensure adequate lubrication is maintained within the system to prevent dry running of the seal lip.
- Contaminant Control: Monitor and control the presence of abrasive particles or corrosive substances in the operating environment, as these can significantly reduce seal life.
- Replacement: Replace the seal immediately if any signs of damage or wear are observed, or if leakage occurs. Consider replacing seals during routine equipment overhauls or at recommended service intervals.
Troubleshooting
This section provides guidance on common issues related to seal performance.
| Problem | Possible Cause | Solution |
|---|---|---|
| Leakage | Improper installation, damaged seal, worn shaft, excessive pressure, incompatible fluid. | Re-install correctly, replace seal, inspect/repair shaft, check system pressure, verify fluid compatibility. |
| Premature Wear | Abrasive contaminants, insufficient lubrication, excessive temperature, shaft runout. | Improve filtration, ensure proper lubrication, check operating temperature, inspect shaft alignment. |
| Seal Hardening/Cracking | High temperatures, chemical incompatibility, aging. | Verify temperature limits, check fluid compatibility, replace seal. |
