Failure Symptoms

The first sign of a failing seal is often a visible fluid leak, such as oil or grease, around the protected component. If left unaddressed, the leak will worsen, potentially leading to lubricant depletion and increased wear on moving parts. Continued operation with a compromised seal risks significant damage to the assembly due to lack of lubrication or contamination.

Installation Tip

Ensure the mating surface on the shaft or housing is perfectly clean and free of burrs before attempting installation. Avoid using excessive force or sharp tools, which can easily damage the new seal during the fitting process.

Service Note

Inspect the shaft or bore for scoring and ensure the lubricant level is adequate after installation.
