Linear guides in robotics systems must withstand extreme loads. In order to detect early wear of its sliding lubrication-free bearings made of high-performance plastics and to plan the maintenance in advance, igus has developed a new smart system for its drylin linear systems.
The system measures the wear of the dirt and dust-resistant bearings and alerts the user when the wear limit is reached. To do this, igus has integrated a sensor in the bearing, which sends the measured data to a communication module, which collects the data from all the sensors, processes them and forwards them. The user can take over the monitoring with the terminal device of choice and therefore carry out maintenance, repair and replacement.
If a bearing change is needed, the replacement takes place directly on the rail, so the linear axis or the multi-axis gantry with toothed belt drive no longer has to be disassembled. The linear plain bearing can be changed quickly and easily with a free tool, reducing downtime to a minimum, and the system can be back in operation within minutes.
