Lubricant and Oil Analysis

What this topic covers

How wear debris, contamination and lubricant condition support machinery health assessment.

Core ideas

Oil can carry evidence about both the lubricant and the machine surfaces it protects.

Water, particles, viscosity changes and wear metals can signal changing conditions.

Sampling consistency is essential because poor sample location or handling can overwhelm the trend.

Program tradeoffs

Load, speed and operating state can change signals even when machine condition is unchanged.

What good evidence looks like

Diagnosis should combine vibration, temperature, lubrication, process and maintenance history where appropriate.

Lifecycle perspective

Monitoring should produce actionable work or engineering review rather than accumulating alarms without response.
