Smart maintenance solution for igus drylin linear guides

igus presents an intelligent solution for the predictive maintenance of drylin
W linear systems.

drylin linear guide systems have to withstand extreme conditions in
continuous operation or even in abrasive environments. In order to have the
linear guides slide without lubricant, igus relies on linear bearings made of
high-performance polymers. When it comes to changing the bearings, the smart igus
linear carriage from Treotham helps: in accordance with the traffic light
principle ‘stop when red, go when green’, the maintenance technician receives
information about the maintenance requirement at the push of a button.

Continuous operation, glass dust and wood fibres are extreme challenges
for the sliding elements in drylin linear guides. igus has developed a smart
drylin linear system to detect wear in the tribo-polymer bearings at an early

A sensor attached directly to the liner measures the wear of the
bearing, which is insensitive to dirt and dust, and gives the user a signal when
the wear limit of 0.5mm is reached. The signal can then be transmitted from the
icom communication module to an intelligent system via Bluetooth, LoRa or LTE
and evaluated.

“On the part of our customers, however, there was also feedback that a
uniform, superordinate and economical system for processing the signals was not
yet available. That’s why we have now additionally developed a solution that
fulfils the function completely without a network connection,” says Stefan
Niermann, head of drylin drive technology at igus GmbH.

Based on the traffic light principle, the maintenance technician can now
find out via a Red/Green LED display on the carriage whether the liner is in
good condition or has already reached the wear limit. All he has to do is press
a button on the carriage, allowing maintenance to be planned in good time.

Bearings changed in seconds

igus has developed a sophisticated replacement technology for quick
exchange of the bearings. This allows the liner to be replaced directly on the
rail. The linear axis or the multiple-axis robot with toothed belt drive no
longer has to be disassembled. A free igus tool from Treotham helps in
dismantling the old bearing and installing the new one. Downtime and
maintenance costs are reduced to a minimum. The system can be put back into
operation within a few minutes and in many cases, does not even need to be
