LUBExpert ON-GUARD
Condition-Based Automated Lubrication System
Starting at:
$7,995
The LUBExpert ON-GUARD is an automated lubrication system that continuously measures bearing friction & condition, then delivers lubrication as required. ON-GUARD’s browser-based software features intuitive dashboards to make accessing, configuring, and controlling your lubrication data straightforward.
Absolutely. ON-GUARD isn’t just any auto-lube system—it uses real-time ultrasound data to measure friction and apply grease only when needed. Unlike traditional systems that operate on timers, ON-GUARD ensures each lubrication decision is based on actual bearing condition, eliminating the risk of over- or under-greasing.
Yes—significantly. By automating routine lubrication and continuously monitoring bearing health, ON-GUARD frees up your team to focus on higher-value tasks. It also reduces manual checks, rework, and emergency interventions, streamlining your entire lubrication process.
ON-GUARD delivers both real-time and historical data on friction levels and lubrication activity. This gives you a clear picture of bearing health over time, helping you predict failures, fine-tune maintenance strategies, and confidently move away from calendar-based routines.
Accurate Ultrasound Friction Monitoring
Operating load, speed, temperature, contamination and other conditions can rapidly deteriorate a bearing and its lubricant, affecting how much replenishment is required. Ultrasound friction monitoring is the most accurate way to monitor for when a bearing needs grease and when it’s had enough.
Lubricate only when needed
Establish a baseline and only grease when friction exceeds that threshold.
Apply the right amount
Stop greasing as soon as the friction levels have reached the desired threshold. Less is often more.
Verify the result
Monitor long-term effectiveness and bearing response after a greasing event.
Convenience of Automated Lubrication, Confidence from Condition Monitoring
ON-GUARD combines the convenience of automatic lubrication with the precision of ultrasound, and the reliability of SDT’s permanently mounted continuous monitoring sensors.
Instead of using a fixed calendar lubrication schedule, ON-GUARD uses real-time ultrasound monitoring and historical bearing data to determine when friction indicates the need for lubrication.
ON-GUARD then delivers a controlled amount of grease whenever it’s required, measures response, and repeats if necessary.
If the ON-GUARD detects something abnormal, it’s capable of sending an alert to the technician that a bearing fault has developed.
Fact: 80% of Premature Bearing Failures are Lubrication Related.

Taking a Data Driven Approach to Machinery Lubrication.
Leverage real-time and historical data to determine optimal friction levels for each asset and establish an alarm threshold. Configure the ON-GUARD to automatically drip-feeds lubrication as needed, preventing over- and under-greasing while maximizing time spent at optimal friction levels.
Continuous Condition Monitoring
Eliminate the need for regular manual condition monitoring inspections with continuous ultrasound monitoring.
8 Automated Lubrication Points Per System
Easily install and scale your lubrication monitoring system with each ON-GUARD unit supporting 8 lubrication points.
Feedback After Every Lubrication Injection
Receive feedback after every lubrication injection. Use data to monitor and optimize the effectiveness of grease.
Working Together
Spend less time reacting to breakdowns and more time preventing them.
