Poor greasing practices are a leading cause of bearing failure. Less than 40% of bearings will last long enough to deliver their engineered value and over or under lubrication is most often to blame.


Many lube departments re-grease on a wasteful calendar-based schedule. But, this leads to over and under greased bearings that fail to deliver their engineered value.

Grease reduces friction in bearings. Less friction means longer life. LUBExpert alerts you when friction levels increase, guides you during re-lubrication, and prevents over and under lubrication.

LUBExpert is an ultrasound solution that helps you Grease Bearings Right. Use the right lubricant at the right location using the right intervals and the right quantities while receiving the right indication of a task well done including bearing status.

The LUBExpert is a complete ultrasound solution to manage your acoustic lubrication program and ensure you GREASE BEARINGS RIGHT.

The LUBExpert Dynamic option connects the Lube Team
with the Condition Monitoring Team

Dynamic data collected by LUBExpert is displayed in Ultranalysis® Suite 3 in the Time and Frequency domain. This dual reliability benefit saves time while removing information silos.

The lubrication team can now collect dynamic data for the condition monitoring team.

Asset condition information is now transparent across departments.

The Dynamic Option completely removes the information gap between lubrication and condition monitoring teams.
By having the Lube Team collect and (if necessary) monitor Dynamic data, it becomes an integral member of the Condition Monitoring Team.

The LUBExpert kit remains the same, the additional Dynamic option can be purchased separately.
