Proper lubrication is critical to bearing reliability and lifespan. In addition to reducing friction, lubricant forms a protective seal that prevents contaminants from entering the bearing and causing damage.
Premature bearing failure, occurring before a bearing reaches its calculated fatigue life, is most often caused by controllable operational factors rather than material defects. The dominant contributors are improper lubrication and contamination.
Other factors such as improper installation and excessive operational stress can contribute to failure. However, improper lubrication is the major cause of all bearing failures, with contamination closely linked as a secondary effect.
Minimum Quantity Lubrication (MQL) is a lubrication technique in which both the quantity and timing of lubricant delivery are precisely calculated and controlled to optimise bearing longevity and performance, rather than relying on irregular or miscalculated greasing practices.
When lubrication quantity and timing are not properly calculated or coordinated, as is often the case with hand greasing, electrochemical single-point lubricators (SPLs), or non-MQL electromechanical SPLs, these traditional greasing methods can lead to multiple failure modes:
In contrast, MQL delivers small, consistent amounts of lubricant at calculated intervals, maintaining a stable and effective lubrication film throughout the bearing's operating cycle.
| Quantity | Interval | Lubrication | Outcome |
|---|---|---|---|
| Too Large | Short | Repeated grease overload | Continuous over-greasing, excessive churning, heat generation, seal damage, grease purge, higher energy consumption |
| Too Large | Long | Initial overload followed by depletion | Initial over-greasing, grease degradation, followed by lubrication starvation before the next application |
| Too Small | Short | Insufficient lubrication film | Continuous under-greasing, unstable lubrication film, increased wear |
| Too Small | Long | Prolonged lubricant deficiency | Severe under-greasing, accelerated wear and premature bearing failure |
| Miscalculated | Any interval | Uneven lubrication delivery | Oscillation between excess and depletion, lubricant degradation, unstable operating temperatures |
| Calculated (MQL) | Calculated (MQL) | Stable lubrication film | Consistent lubrication, minimal degradation, extended bearing life |
| Aspect | Traditional | MQL |
|---|---|---|
| Basis for lubrication timing | Timers, calendars, or maintenance routines | Calculated intervals based on bearing requirements |
| Basis for lubrication quantity | Fixed or estimated grease volumes | Precisely calculated lubricant quantities |
| Response to runtime | Not considered | Matched to actual runtime |
| Response to load changes | Not considered | Adjusted to bearing load conditions |
| Response to speed variations | Not considered | Matched to bearing speed |
| Response to temperature | Not considered | Accounts for temperature effects on lubricant consumption |
| Alignment with bearing consumption | Poorly aligned | Directly matched to lubricant consumption |
| Lubrication outcome | Periods of overload or deficiency | Stable, continuously renewed lubrication film |
| Typical result | Over-greasing, under-greasing, or uneven lubrication | No overload, no starvation, consistent protection |
Easylube's MQL-enabled SPL with configurable grease fill quantities bridges the gap between MQL and routine maintenance by aligning lubrication delivery with both bearing demand and maintenance routines. This eliminates over- and under-greasing, reduces waste at changeout, and minimises environmental risk, such as excess grease contaminating the surrounding area.
A robust maintenance program, whether corrective, preventive, or predictive, requires skilled and knowledgeable personnel to carry out lubrication-related activities. To achieve optimal reliability and maximise the benefits of a lubrication program, several factors must be considered, including the well-known Five 'R's of Lubrication:
The Easylube single-point EX lubricator is a maintenance-free, cost-effective, and easy-to-operate device specifically designed for MQL formulations. Its reliable dispensing control and straightforward operation have earned it a strong reputation in the market. The system helps ensure bearings remain in optimal working condition, even in harsh environments, demanding operating conditions, and varying weather situations.
Using OEM specifications as a baseline, our software enables the calculation of MQL requirements based on each bearing's operating conditions. The dispense period of the Easylube single-point automatic lubricator is then configured according to the bearing-specific MQL formulation.
RFID tags on the EX devices are used to identify lubrication points for patrol inspection and monitoring. By simply scanning the RFID tags with a compatible smart device (e.g., mobile phone, tablet), maintenance tasks can be performed directly through the software.
Use of approved grease cartridges and certified batteries is also essential to optimise product performance, prevent contamination, and minimise fire and explosion risk.
If required, our reseller network can connect you with lubrication specialists who provide advanced grease formulations to maximise performance and extend the life of your equipment.
This automatic Single Point Lubricator eliminates manual effort and variability from manually greasing bearings. Designed as a highly stable, continuous-duty device, it operates 24/7 without interruption and withstands extreme conditions in hazardous environments.
By reducing the need for manual greasing in hazardous zones, the EX Series significantly improves onsite safety and operational reliability.
