Single-line lubrication for clean and defined dosage
Single-line lubrication is powerful when lubricant needs to be delivered to specific locations in clearly defined quantities and a clean, controllable system is required.
Technical classification
Single-line lubrication is interesting in many industrial applications when lubrication points need to be supplied in a targeted and metered manner. Applications with oil or light lubricating media are typical, where reproducibility is more important than maximum robustness for heavy grease cases.
The strength of the system lies in the orderly supply of individual points. This makes it well suited for guides, chains, smaller machines and systems with clear lubrication logic.
The decisive factor for the selection is how well the medium, timing, pressure level and distribution fit together. Single-line lubrication only works really well if the dosing principle and process requirements come together cleanly.
Technical selection criteria
The focus is on dosage, medium and repeatability.
Dosing accuracy
The system design must ensure reproducible quantities at the individual lubrication points.
Timing
Lubrication intervals and process frequency directly influence the selection of pumps and dosing devices.
Installation situation
Line routes, accessibility and process environment must be taken into account during planning.
Single-line lubrication wins when clean metering and system clarity are the priority.
Applications in industry, construction machinery and trucks
The typical applications are usually more stationary than with grease systems, but mobile special cases also occur.
Industry
Guides, chains, smaller machines and defined lubrication points benefit from the orderly dosage.
Construction machinery
In special mobile applications, initiation is the exception, but can be useful for oil-related tasks.
LKW
In specific auxiliary units, discharge can become relevant where oil-based supply must run in a controlled manner.
Comparison and system delimitation
The most important demarcation oil runs against grease systems and against large two-pipe networks.
| criterion | Single-line lubrication | Progressive lubrication | Dual line lubrication |
|---|---|---|---|
| Typical strength | Clean single point dosing | Compact monitorable network logic | Strong in large networks |
| Typical media | Oil and light fats | Often fat or system dependent | Mostly larger industrial systems |
| Best operating location | Clear individual points | Compact to medium network structure | Lots of lubrication points and long lines |
| Commercial Path | Oil pump | Progressive lubrication | Dual line lubrication |
When clean dosing is a priority, induction is often a clearer route than a more complex fat system.
ROI, procurement and consulting
The benefits arise from less incorrect lubrication, better process stability and less service effort at defined lubrication points.
The system is particularly interesting from an economic point of view when manual lubrication is uneven or difficult to standardize.
When it comes to procurement, it is crucial that single-line lubrication, oil pump and application are evaluated together.
FAQ
When does single-line lubrication make sense?
When individual lubrication points need to be supplied with clearly defined quantities.
Which media are typical?
Especially oil and light fats with easily controllable conveying behavior.
Single-line lubrication is typical for heavy construction machinery
Rather rare. There, grease systems and progressive solutions are usually closer to practice.
Do I need an oil pump for this?
Often yes, because many single-line applications are oil-related.
How does the system differ from progressive
Introduction focuses on defined dosage of individual points, progressive more on a compact network logic with a clear distribution sequence.

Adjust the inlet lubrication precisely to the medium and process
If the dosing requirements, medium and timing are clearly described, single-line lubrication can be designed very precisely and economically.
What is single-line lubrication?
Single-line lubrication means the metered individual delivery of lubricant to defined points per switching cycle. The method is strong when quantity precision and timing reference are important.
How it works What is single-line lubrication
The pump supplies the network cyclically, whereupon dosing devices deliver the intended quantities to the lubrication points. Print window, medium and timing are crucial for reproducible results.
Application cases
Typical applications are guides, chains and machine modules with recurring load profiles and clear dosing requirements.
Advantages
The advantages are high quantity control, good scalability in the system environment and clearly assessable lubrication performance.
Comparison with alternatives
Compared to other methods, single-line lubrication is particularly suitable when precise individual quantities in the process must be clearly detectable.
