How LUBExpert Cuts Lubrication Costs by 50%
Real savings figures from ultrasonic bearing-lubrication control. See how plants cut lubrication spend by 30-50%.

Introduction
Lubricants are one of the largest line items in a maintenance budget. At a large industrial plant, the annual grease and oil budget can run into hundreds of thousands of dollars.
But what if up to 50% of that budget is being wasted?
That's not an exaggeration. It's the figure from real audits at plants that have deployed LUBExpert.
The scale of the problem
Let's look at a typical scenario.
A typical plant
Picture a plant with:
- 500 large bearings in service
- Annual grease consumption: 2,000 kg
- Grease cost: $15/kg
- Annual lubrication budget: $30,000
The problem
Under a traditional "by the calendar" approach:
- 40–60% of bearings are over-greased
- 25–30% of bearings are greased when it isn't needed
- Only 15–35% of bearings actually need lubrication
The result: up to 70% of the grease applied is wasted.

SDT instrument for precision ultrasound-guided greasing of rolling element bearings: tells you when to add grease and when to stop, follows routes from UAS3 and closes…
How LUBExpert saves money
LUBExpert solves the over-greasing problem through objective control.
How it works
- Measurement before lubrication — the instrument shows the current condition
- Real-time monitoring during application — actual signal-level tracking
- Stop at the right moment — the system signals the optimum point
- Documentation — a history for every bearing
The result: precision instead of guesswork
With LUBExpert you know exactly:
- Whether this bearing needs greasing right now
- Exactly how much grease to apply
- When to stop
Real savings figures
Let's look at actual results from LUBExpert deployments.
Case 1: Mining and processing plant
| Metric | Before LUBExpert | After LUBExpert | Savings |
|---|---|---|---|
| Grease consumption | 120 kg/month | 66 kg/month | 45% |
| Annual budget | $21,600 | $11,880 | $9,720/year |
| Investment | — | on request | — |
| Payback | — | 31 months | — |
Case 2: Metallurgical plant
| Metric | Before LUBExpert | After LUBExpert | Savings |
|---|---|---|---|
| Grease consumption | 180 kg/month | 90 kg/month | 50% |
| Annual budget | $32,400 | $16,200 | $16,200/year |
| Investment | — | on request | — |
| Payback | — | 22 months | — |
Case 3: Oil refinery
| Metric | Before LUBExpert | After LUBExpert | Savings |
|---|---|---|---|
| Grease consumption | 95 kg/month | 57 kg/month | 40% |
| Annual budget | $17,100 | $10,260 | $6,840/year |
| Investment | — | on request | — |
| Payback | — | 35 months | — |
Additional savings
Reduced grease consumption is only part of the savings.
Lower disposal costs
Excess grease contaminates equipment and requires disposal.
- Cleanup costs: $5–10/kg
- Disposal costs: $3–5/kg
- Total savings: an extra 10–15% on top of the lubrication budget
Longer bearing life
Correct lubrication extends bearing life by 40–60%.
- Average bearing cost: $500–2,000
- Replacements per year: 50 units
- Savings on replacements: $10–30,000/year
Fewer outages
Fewer failures mean fewer outages.
- Outage cost: $50–500/hour (industry-dependent)
- Reduction in failures: 70–80%
- Outage savings: $100,000–500,000/year
ROI on deployment
Let's run the overall ROI for a typical plant.
Investment
- LUBExpert kit and staff training: price on request, depends on the configuration.
Annual savings
| Savings source | Amount |
|---|---|
| Reduced grease consumption | $12,000 |
| Lower disposal costs | $2,000 |
| Longer bearing life | $15,000 |
| Reduced outages | $50,000 |
| Total annual savings | $79,000 |
Payback
- Annual savings: $79,000
- Payback = kit and training cost / annual savings. Use the price from your quotation.
How to start saving
Step 1: Audit the current situation
Assess:
- Current grease consumption
- Grease cost
- Number of bearings
- Failure frequency
Step 2: Pilot project
Start with critical bearings:
- Select 20–50 bearings
- Deploy LUBExpert
- Collect data for 3 months
Step 3: Analyze the results
Compare:
- Grease consumption before and after
- Bearing condition
- Failure frequency
Step 4: Scale up
Expand the deployment:
- To all critical bearings
- Then to all equipment
- Integrate with your CMMS
Conclusion
Saving money on lubrication isn't a myth. It's a reality proven at dozens of plants.
LUBExpert gives you objective data for decision-making and turns lubrication from a cost center into a savings tool.
