Setup and Installation
Proper installation is critical for the effective performance and longevity of the SKF Seal 24898. Always refer to the vehicle manufacturer's service manual for specific instructions related to your application.
General Installation Guidelines:
- Preparation: Ensure the shaft and bore surfaces are clean, smooth, and free from burrs, nicks, or corrosion. Any surface imperfections can compromise the seal's integrity.
- Lubrication: Lightly lubricate the seal lips and the shaft with the same lubricant that the seal is intended to retain. This aids in smooth installation and prevents initial dry running.
- Installation Tool: Use a proper seal installation tool or a suitable sleeve to press the seal squarely into the bore. Avoid using hammers directly on the seal, as this can deform it or damage the sealing lips.
- Alignment: Ensure the seal is installed straight and to the correct depth in the bore. Misalignment can lead to premature wear and leakage.
- Shaft Entry: When sliding the seal over the shaft, be careful not to damage the sealing lips on sharp edges or splines. Protective sleeves or tape can be used if necessary.
- Final Check: After installation, visually inspect the seal to ensure it is seated correctly and the lips are not inverted or damaged.
Operating Principles
The SKF Seal 24898 functions as a rotary shaft seal, designed to create a barrier between two environments, typically to retain lubricating oil or grease within a system while preventing the ingress of external contaminants like dirt, dust, and moisture.
Its dual-lip design provides enhanced sealing capability, with one lip primarily for fluid retention and the other for contaminant exclusion. The integrated spring applies a consistent radial force to the sealing lip, maintaining contact with the rotating shaft and ensuring effective sealing throughout its operational life.
The Nitrile Rubber material is selected for its excellent resistance to petroleum-based oils and greases, as well as its ability to perform reliably across a wide range of temperatures common in automotive applications.
Maintenance
SKF seals are designed for long-term, maintenance-free operation under normal conditions. However, periodic inspection of the sealed area can help identify potential issues before they lead to significant problems.
Inspection Guidelines:
- Visual Check: Periodically inspect the area around the seal for any signs of lubricant leakage or excessive dirt accumulation.
- Noise: Listen for any unusual noises coming from the sealed component, which could indicate a failing seal or bearing.
- Temperature: Check for any abnormal heat generation around the seal, which might suggest excessive friction or improper installation.
If any signs of leakage or seal degradation are observed, the seal should be replaced promptly to prevent damage to other components.
Troubleshooting
Most issues with rotary shaft seals are related to improper installation or extreme operating conditions. Here are some common problems and their potential causes:
| Problem | Possible Cause(s) | Solution |
