Why do you need Viewports?

Viewports are designed for use on the centerline of equipment's oil level.

Oil Level

Improper oil level, low or high, is one of the leading causes of equipment failures.

Oil Appearance

Cloudy appearance of oil in the level gauge may indicate water is present in the oil.

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.

Spring Cleaning for Your Lubrication Program

Spring is the perfect time to refresh your lubrication practices with simple steps like purging old lubricants, checking desiccant breathers, updating labels, and evaluating PM routes. This seasonal tune-up not only boosts cleanliness and efficiency but also helps extend equipment life. If you need guidance, a Lubrication Program Assessment can help identify opportunities for improvement and reliability gains.
