Accurate & Stable Lubricant Injection with RFID Tracking Software
Available in 500, 250, 150, and 60 ml (cc) capacities, these automatic Single Point Lubricators (SPLs) eliminate the manual effort and variability associated with traditional bearing greasing. Designed for continuous duty, they operate 24/7 without interruption and are engineered to perform reliably in extreme environmental conditions.
All RFID models incorporate embedded RFID tags that interface with inspection software to provide accurate asset identification, service verification, and complete maintenance traceability. The system also enables the generation of structured maintenance task lists, supporting consistent inspections and proactive servicing.
The RFID-Plus represents the next evolution in performance and control. Featuring a 6th-generation smart control circuit and patented enhanced gear mechanism with laser sensor feedback, it delivers highly stable output pressure and precise lubrication even in demanding applications. This advanced design effectively overcomes challenges such as long extension lines, small grease nipple diameters, and high-viscosity or thickened greases.
Additional capabilities include pre-warning alerts for abnormal grease pressure, multifunctional three-color LED status indicators, and onboard memory storage that synchronizes with equipment power on/off cycles. Available in a 500 ml configuration, RFID-Plus is engineered for extended service intervals and higher-duty applications.
For operations aligned with custom maintenance schedules, RFID-Flex provides the same core features as RFID-Plus, with dispensing cycles configurable for weekly operation.

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.
MQL is a lubrication technique in which both the quantity and timing of lubricant delivery are precisely calculated and controlled to optimize 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 Short-Interval Greasing | Minimum Quantity Lubrication (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:
