Lubrication Systems - Complete Solutions for Reliable Lubrication
When bearings run dry, chains squeak, or guides seize, lubrication is usually the hidden culprit. Central lubrication systems automatically supply every lubrication point with the right amount of oil or grease, precisely, repeatably, and cleanly. The result: less wear, longer service life, and predictable maintenance. Our range includes dosing pumps, oil/air components, distributors, installation tools, and accessories, available at short notice with worldwide shipping.
How a Central Lubrication System Works
A pump feeds the lubricant into a main line. From there, metering devices or distributors deliver precisely measured quantities to each lubrication point, such as bearings, guides, or chains. Depending on the system, lubrication is time-based or demand-controlled. Both approaches reduce manual relubrication and prevent over- or undersupply. This method is established in single-line and progressive systems and can be integrated into both new and existing equipment.
Building Blocks of a Lubrication System
- Pumps & metering units: The heart of the system. For grease or oil; manual, electric, pneumatic, or hydraulic drive. Selection depends on lubricant, number of points, and cycle.
-
Distributors/progressive distributors: Ensure repeatable quantities per lubrication point, even with changing temperatures or vibration.
-
Lines, hoses & lubrication fittings: Precise, leak-tight connections are essential. Metric, imperial, or SAE; straight, elbow, or T-shape; brass, steel, or stainless steel. This keeps lubricant in the system without loss, even under pressure.
-
Oil/air components: For applications where minimally metered quantities are transported with air to hard-to-reach points.
-
Installation & expansion tools: For clean installation, quick adjustments, and extending existing systems.
Benefits at a Glance
Precise dosing & less wear
Every point gets exactly what it needs. This reduces friction, temperature, and failures. Automation cuts maintenance effort and saves labor time.
Predictability
Interval- or sensor-based signals make lubrication plannable and downtime less frequent.
Integrability
Central systems fit both new builds and retrofits, with standardized threads, compatible fittings, and modular distributors.
Cost-effectiveness
Less lubricant waste, higher machine availability, and lower long-term cost per operating hour.
Typical Applications
-
Mechanical engineering & manufacturing: Machine tools, machining centers, transfer and assembly systems.
-
Construction & agricultural machinery: Even supply of pins, joints, bearings, and guides, even under vibration.
-
Conveying technology: Roller conveyors, chain conveyors, lifting and hoisting systems.
-
Food & packaging industries: Clean, precise oil/grease quantities and hygienic stainless-steel fittings.
-
Energy & recycling plants: Continuous operation under load where reliable, loss-free supply is critical.
These industries benefit especially from leak-tight connections and corrosion-resistant components that prevent leakage and maintain stable pressure.
Systems & Variants - How to Choose the Right One
Single-line systems
Universal, robust, and suitable for many lubrication points. Metering devices are supplied via a main line. Control can be time- or cycle-based. Ideal where flexibility and easy retrofitting are desired.
Progressive systems
High-precision distribution in a defined sequence. Each dose is traceable. Well-suited where monitoring the function of individual lubrication points matters.
Oil/air lubrication
Micro-dosing with air transport, for example for high-speed spindles or hard-to-reach locations. Saves lubricant and keeps areas clean.
Drive types
Electric pumps for automated cycles. Pneumatic/hydraulic variants where media are already available. Hand-operated solutions for simple, occasional tasks.
Fittings & Lines - Small Parts, Big Impact
Leak-tight connections are the backbone of any lubrication system. Our lubrication fittings consist of precisely matched components (nut, cutting ring/clamp body, thread) and ensure permanently tight, vibration-resistant line connections, even with repeated assembly. Available with metric, imperial, and SAE threads, as straight, 45°/90° elbows, T- and cross versions. Materials such as brass, zinc-plated steel, or stainless steel provide corrosion protection and mechanical stability, which is crucial in food, energy, or recycling environments.
Selection Criteria: What Really Matters
-
Lubricant & temperature range: Not every pump handles every lubricant equally well. Viscosity and temperature window determine pumpability and dosing accuracy.
-
Number/distance of lubrication points: Line lengths, pressure losses, and the required distribution concept (single-line vs. progressive) must align.
-
Operating mode & control: From fixed intervals to sensor/PLC integration. The more automated, the more consistent the quality.
-
Serviceability: Standardized threads, modular distributors, and easily accessible components shorten maintenance times.
-
Environmental influences: Vibration, humidity, cleaning agents. Choose fittings and lines accordingly, for example stainless steel in hygiene-critical areas.
