Safety Information

Always prioritize safety during installation and maintenance. Read all instructions carefully before proceeding. Wear appropriate personal protective equipment (PPE) such as gloves and eye protection. Ensure the equipment is de-energized and depressurized before working on any sealing components. Improper installation can lead to equipment damage or personal injury.

Setup and Installation

Proper installation is crucial for the effective performance of the double lip seal. Follow these general steps:

Preparation:
- Ensure the shaft and housing bore are clean, free from burrs, scratches, and foreign particles.
- Verify that the new seal matches the specifications (50 x 62 x 5mm) and is the correct type for the application.
- Lightly lubricate the seal lips and the shaft with the system's operating fluid or a compatible lubricant to aid installation and prevent initial dry running.
Seal Installation:
- Carefully slide the seal onto the shaft, ensuring the sealing lips face the correct direction (typically with the primary lip facing the fluid to be sealed).
- Use a suitable installation tool or a smooth, blunt object to press the seal evenly into the housing bore. Avoid using sharp tools or excessive force, which can damage the seal.
- Ensure the seal is seated squarely and fully within the bore, without tilting or distortion.
Post-Installation Check:
- After installation, rotate the shaft manually to confirm smooth movement and proper seating of the seal.
- Visually inspect the seal for any signs of damage or improper installation.

For specific equipment, always refer to the original equipment manufacturer's (OEM) service manual for detailed installation procedures.

Operating Principles

The S.7760 Double Lip Seal is a dynamic sealing component designed to prevent the leakage of lubricants or other fluids from a rotating shaft while simultaneously excluding external contaminants like dust and dirt. The primary lip provides the main sealing function against fluid pressure, while the secondary lip offers additional protection against external elements and can also act as a backup seal. Proper lubrication and operating conditions are essential for its long-term effectiveness.

Maintenance

Regular inspection and maintenance can extend the life of your double lip seal and prevent premature failure.

Visual Inspection: Periodically check the seal area for any signs of leakage, cracking, hardening, or excessive wear on the seal lips.
Shaft Condition: Inspect the shaft surface for any signs of wear, scoring, or corrosion that could compromise the seal's integrity.
Lubrication: Ensure that the seal is adequately lubricated by the system's fluid. Dry running conditions can rapidly degrade the seal material.
Replacement: Replace the seal immediately if any signs of damage or leakage are observed. Seals are wear components and should be replaced as part of routine preventative maintenance or during equipment overhaul.

Troubleshooting

If you encounter issues with the seal, consider the following common problems and their potential causes:

Problem	Possible Cause	Solution
Fluid Leakage	Improper installation (e.g., seal tilted, damaged during installation) Worn or damaged seal lips Excessive shaft runout or vibration Incorrect seal size or material Shaft surface damage (e.g., scoring, corrosion)	Reinstall seal correctly, ensuring proper seating. Replace the seal. Inspect and correct shaft alignment or balance. Verify seal specifications and replace with correct part. Repair or replace damaged shaft.
Premature Wear	Lack of lubrication (dry running) Excessive operating temperature Presence of abrasive contaminants Improper shaft surface finish Chemical incompatibility with fluid	Ensure adequate lubrication. Check system cooling; use higher temperature rated seal if necessary. Improve contamination exclusion measures. Ensure shaft surface finish meets requirements. Verify seal material compatibility with fluid.

If troubleshooting steps do not resolve the issue, consult a qualified technician or the equipment manufacturer.
