Protecting Your Equipment

I recently looked at the analyst ratings of the tens of thousands of samples processed through our lab in 2020. I took all the samples related to bearings, gears, and hydraulic systems and summarized the analyst’s rating based on the test results. One thing is clear. Reliability and maintenance personnel continue to struggle with maintaining the quality of their lubricant. 35% of samples claim a Serious/Critical status, 27% proceed with caution, and only 38% are considered normal.

When done with precision, consistency, and attention to detail, lubrication extends equipment life and prevents costly failures. In reliability, as in life, the small things are the big things.
