A4910 Lubri
Handheld instrument for vibration-based lubrication of roller bearings
Proper lubrication is crucial for the lifetime of rolling bearings. With the A4910 Lubri, you get a handheld instrument that allows you to perform lubrication based on measurements instead of fixed time intervals.
The instrument utilises Shock Pulse technology, which detects friction and shock in the bearing. During lubrication, the instrument provides real-time feedback so the operator can see how the condition of the bearing changes as grease is applied.
This makes it possible to stop lubrication exactly when the bearing is correctly lubricated. The result is less grease consumption, lower temperatures and longer bearing life.
A4910 Lubri - vibration-based lubrication of bearings
In many organisations, lubrication is still performed at calendar-based intervals. This can lead to both overlubrication and insufficient lubrication, which are among the most common causes of bearing damage.
With A4910 Lubri, lubrication can instead be performed based on measurements of the bearing condition.
The instrument makes it possible to:
- Identify bearings that lack lubrication
- Monitor the effect of lubrication in real time
- Stop lubrication when optimal condition is reached
This provides a more consistent lubrication process and reduces the risk of errors caused by incorrect lubrication.
What problems can A4910 Lubri identify?
Using Shock Pulse measurements, A4910 Lubri can help identify several typical problems related to bearings:
- Insufficient lubrication
- over-lubrication
- Incipient bearing damage
- increased friction in bearings
- Increased shock pulses from rolling elements
When a bearing lacks lubrication, the Shock Pulse value will typically increase. Under proper lubrication, the value will decrease again, giving a clear indication of when lubrication is sufficient.
Measurement features of the A4910 Lubri
Developed specifically for lubricating roller bearings, the A4910 Lubri combines several features that make lubrication work more precise and efficient.
Shock Pulse measurement:
The instrument measures Shock Pulse signals from the bearing, which are sensitive to friction and shock between rolling elements and raceways. This makes the method suitable for assessing lubrication condition.
Real-time lubrication control:
During lubrication, the operator can see how the signal changes as the grease is applied. When the signal stabilises at a lower level, the bearing is properly lubricated.
Visual indicator:
The instrument clearly shows if the bearing is:
- correctly lubricated
- under-lubricated
- over-lubricated
This makes the process more consistent between different operators.
Quick measurement:
Measurements are quickly taken directly on the machine, making it ideal for daily maintenance and lubrication rounds.
DDS analysis software
Measurement data from the A4910 Lubri can be transferred to PC where it can be stored and analysed over time.
With the help of DDS (Digital Diagnostic System), companies can work more systematically with lubrication and condition monitoring.
It gives you the opportunity to:
- Follow the development of the condition of the bearing
- Document lubrication work
- Compare measurements over time
- Build fixed measurement routes and lubrication points
This way, lubrication can be integrated as part of the company's predictive maintenance strategy.
Typical applications
A4910 Lubri is typically used on rotating machines with roller bearings, for example:
- electric motors
- fans
- pumps
- carriers
- gear
- process equipment in industry
The tool is particularly suitable for companies with many manually lubricated bearings where a more structured approach to lubrication is needed.
By combining lubrication and vibration-based condition assessment, companies can reduce both maintenance costs and unplanned downtime.
