Even a small quantity of hard particles can disrupt the lubricant film and dent raceways. Water also promotes corrosion and changes lubricant properties.
Protection must be a complete system: suitable seals, clean installation, correct storage, controlled relubrication and careful washing around the arrangement.
What to Focus On
- labyrinth and contact seals
- correct seal-lip orientation
- clean housing breathers
- safe machine-washing practice
- regular checks of lubricant colour and consistency
Recommended Procedure
- Identify the type and direction of contamination.
- Inspect seals and adjacent running surfaces.
- Establish a clean relubrication routine.
- Watch for moisture and corrosion after washing or shutdowns.
Common Mistake
A direct high-pressure water jet can force moisture through the seal of an otherwise well-protected arrangement.
Summary
The strongest protection combines sound design, cleanliness and disciplined operating practice.
