🔍 Why Grease Performs Well in Lab but Fails in Field?

In many plants, grease passes all lab tests — yet fails during actual operation.

From my practical experience, the biggest gap is:

👉 Difference between controlled lab conditions and real-world operating environments

Key reasons:

• Contamination (dust, water ingress)
• Improper re-lubrication intervals
• Wrong grease selection for load/speed conditions
• Additive depletion over time
• Mixing of incompatible greases

👉 In reality, lubrication is not just a product — it is a system.

✔ The right grease
✔ Proper application method
✔ Continuous condition monitoring

These together decide performance.

📌 Insight: Most failures are not due to grease quality, but due to application and system control.
