igus recently added the intelligent plain bearing to its range of smart plastics products that detects wear in extremely stressful applications in advance and sends a signal to the user in good time if the bearing threatens to fail. Maintenance work can therefore be planned and operators of agricultural machines, for example, are not surprised during the harvest season. Discussing the features of new bearing, Stefan Loockmann-Rittich, Head of the Business Unit iglidur plain bearings, igus GmbH, explained, "We have primarily developed smart iglidur for difficult-to-access bearing points and for applications where no regular maintenance intervals have been planned."
The body of the new smart iglidur plain bearing consists of two components: the internal, lubrication-free iglidur material and an outer hard polymer shell that protects the bearing. The customer can choose the material that is most suitable for his application as the complete range of iglidur materials is available to him. In order to measure the amount of wear, an intelligent sensor is used between the two components. The measured data of the sensor can be integrated by the machine and equipment operators in their systems in different ways. For example, it is possible to inform the operator about the plain bearing's wear by means of a warning light, where an automatic cut-off is also a possibility for integrated use of the sensor data. For high-end applications, the data can be sent directly to a control system, which, after their analysis, passes the data on to a customised web interface via the icom communication module for the purposes of maintenance and repair. In this way, the user can plan maintenance and replacement by means of a terminal device of his choice.
