SKF

Single-line Lubrication Systems

SKF single-line lubrication systems are designed for small-to-medium line lengths and are compatible with almost all lubricants. Operating on a simple yet effective principle, a central pump station automatically delivers lubricant through a single supply line to metering devices.

Each metering device serves a specific lubrication point and can be adjusted to release the exact amount of grease or oil required. The system is versatile, capable of servicing a single machine, distinct zones on one machine, or even multiple separate machines.

Benefits

    • Easy to understand, install and maintain

    • Suitable for nearly all types of lubricants

    • Reliable operation with minimal downtime

    • Simple to expand or adapt for growing systems

    • Continues to run even if one point becomes blocked

    • Capable of pumping long distances and performing across a wide temperature range

    • Improves worker safety through automated, consistent lubrication

    These advantages make SKF single-line systems an ideal solution for industries seeking efficiency, safety, and precise control over lubrication.

Applications

  • SKF single-line systems are used across a wide range of industrial and manufacturing sectors, including:

    • Machine tools

    • Automation and robotics

    • Printing machines

    • On- and off-road vehicles

    • Construction and forestry machinery

    • Cement and materials handling

    • Food and beverage processing

    • Railway and transportation systems

    • Steel and heavy industry

    Their flexibility and reliability make them suitable for both standard and demanding environments.

    How Single-Line Metering Devices Work

    All single-line metering devices operate almost in parallel, allowing for even distribution of lubricant. There are two main working principles, depending on system requirements.

Pre-lubrication metering devices:

In this type of system, the pump feeds lubricant through the main line into the metering device. Each discharge delivers a pre-stored amount of lubricant to the lubrication points, driven by the pump’s pressure.

Once the main line is relieved of pressure, the remaining lubricant shifts into the accumulator inside the device, ready for the next lubrication cycle. This process ensures consistent and repeatable delivery, keeping machinery running smoothly.

Re-lubrication metering devices:

During each lubrication cycle, lubricant flows into the accumulator chambers of the metering devices. The stored quantity is released only after the main line’s pressure has been relieved. This process – known as the re-lubrication effect – provides controlled, metered discharge to each lubrication point.

Quantities for both pre- and re-lubrication systems can be easily adjusted by changing the metering nipples, allowing for simple system tuning and maintenance.
