Thinks with you and thinks for you.

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. 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

Bearing Database

LUBExpert maintains a database of all your assets including bearing type and dimensions.


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

Guided & Free Modes

LUBExpert offers two modes to grease bearings right; "free" and "guided". Whether your program is mature, or just getting started LUBExpert helps you grease bearings right.

LUBExpert’s Onboard Ultrasound Assistant ensures you



Different applications require different lubricants. Which one is the right one? LUBExpert’s onboard assistant helps you select the correct grease and reminds you of the bearing’s maximum capacity.


With potentially thousands of assets to manage, how can you be sure you’re greasing the right bearings? LUBExpert’s onboard assistant guides you through your plant using UAS’s tree structured navigation.


Whether you lubricate on a calendar-based or condition-based schedule, LUBExpert and Ultranalysis Suite alert you when bearings are due for relubrication. Alarms triggered by SDT’s evolutionary FOUR CONDITION INDICATORS make sure the “squeaky wheel” gets the grease on time.


Over and under lubrication are to blame for most lubrication related failures. LUBExpert’s onboard assistant continuously calculates friction levels between half shots of grease advising you to add more – or stop when optimal friction levels are reached.


LUBExpert delivers confidence to the task of re-greasing bearings. The onboard assistant guides you smoothly through the task and concludes with a GOOD, BAD, or SUSPECT result. Activities are tied back into UAS Suite data management software where logical reports illustrate before and after, quantity of grease added per point, and total grease consumed by department or plant.

“Our maintenance teams have taken a keen interest in the compatibility of utilizing SDT ultrasound instruments and marrying that technology with vibration analysis to get a deeper understanding of our assets and detecting failures prior to them becoming catastrophic. Outstanding products with outstanding people make SDT an awesome part of the maintenance reliability world.”

Doug Stangier – Maintenance Manager, CMRP CRL

Alexandre Vigean “Ultrasonic measurements can detect potential problems on bearings and also confirm assumptions of wear. These functions were successfully identified by SDT and our team during a survey. With this first experience and equipped with our new instrument, we are now able to propose to our customers a survey of their bearings in order to monitor them and to make an early diagnosis of the state of wear of the rotating elements. ”
