Monitor Greasing and Lubrication with LUBExpert

The reason behind frequent bearing failure is improper grease application. Only about 40% of bearings will last long enough to offer their engineered value, and the most common cause is improper lubrication.

Several lube departments make use of a wasteful calendar-based re-greasing plan. Consequently, bearings are over- and under-greased, thereby failing to provide the engineered value.

Bearing grease reduces friction. Longer life suggests less friction. When the levels of friction are increased, LUBExpert alerts users, leading them through re-lubrication, and avoids over- and under-lubrication.

LUBExpert is an ultrasonic solution that helps users lubricate bearings appropriately. Utilize the correct lubricant at the appropriate location, at the proper intervals, and in the right quantities, all while receiving the suitable indicator of a job well done, such as bearing status.

Database of Bearings

LUBExpert helps keep track of all of the users’ assets, such as bearing types and dimensions, in a database.


LUBExpert removes the guesswork by assessing the stabilization time between grease pumps automatically.

Modes: Guided and Free

LUBExpert consists of two modes for rightly lubricating bearings: “free” and “guided.” LUBExpert could help users correctly grease bearings even when the program is well-established or just getting initiated.

Shopping List

LUBExpert advises users to make the proper grease type and quantity for the lube operations of the day.

Work Orders

LUBExpert reminds users which bearings would need grease. Users can restore their lubrication program’s order and discipline.

System Messaging

LUBExpert makes use of messaging to document and inform the users’ team on why a few assets were ignored.

The Onboard Ultrasound Assistant in LUBExpert guarantees that users grease bearings correctly.

The Right Lubricant

Various lubricants are needed for different uses, but which is the right option? The onboard assistant from LUBExpert helps the user choose the right grease and reminds them of the maximum capacity of the bearing.

The Right Location

How can users be sure that they are lubricating the right bearings when they are dealing with thousands of assets? LUBExpert’s onboard assistant utilizes a tree-structured navigation system to help users navigate through their plant.

The Right Interval

LUBExpert and Ultranalysis Suite 3 help inform users when bearings are due for relubrication if they lubricate on a calendar-based or condition-based timetable. The “squeaky wheel” gets the grease on time as a result of alarms triggered by SDT’s evolving FOUR CONDITION INDICATORS.

The Right Quantity

The majority of the lubrication-related failures are caused by surplus or inadequate lubrication. The onboard assistant in LUBExpert consistently evaluates friction levels between half shots of grease. This urges users to apply more or stop when optimal friction levels are encountered.

The Right Indicators

The job of re-greasing bearings is made simpler with the help of LUBExpert. The onboard assistant walks users via the task and gives them a good, bad or suspect result. The activities are connected to the UAS3 Suite data management software, producing logical reports that exhibit the amount of grease added per point, the before and after, and the total amount of grease used by the department or plant.

The LUBExpert Dynamic Option Connects the Lube Team with the Condition Monitoring Team

Dynamic data gathered by LUBExpert is exhibited in Ultranalysis® Suite 3 in the Time and Frequency domain. The benefit of dual reliability helps save time while eliminating information silos.

  • The lubrication team can gather dynamic data for the condition monitoring team.
  • Asset condition information is transparent throughout different departments.

The Dynamic Option entirely eliminates the data gap between lubrication and condition monitoring teams.

The Lube Team collecting and (if essential) monitoring Dynamic data makes it an integral member of the Condition Monitoring Team.

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