๐Ÿ” 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:

๐Ÿ‘‰ 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

๐Ÿ‘‰ In reality, lubrication is not just a product — it is a system.

โœ” The right grease
โœ” Proper application method
โœ” Continuous condition monitoring

These together decide performance.

๐Ÿ“Œ Insight: Most failures are not due to grease quality, but due to application and system control.
