Bearings are a globally sourced commodity. As such, quality control of regular deliveries as well as the evaluation of new suppliers is highly important. The common methods for quality control are either insufficient for detecting most serious flaws or require significant time, effort, and money. Rapid lifetime testing is a
When scientific research aims to break down the existing limits of machine elements, the associated equipment must meet the highest demands. Professor Kirchner and his team at the Technical University of Darmstadt (TUD) intend to use the electrical properties of rolling contact bearings for various purposes, including as sensors. This
When selecting a bearing supplier for industrial machinery, one typically needs more than just a bearing. In fact, what one really needsis a three-tiered serviceconsisting of application engineering, the bearing itself, and preventative maintenance services such as diagnostics and condition monitoring. Operators of industrial plants such as steel mills and
Our newest EELPRAAX-130 test rig "Laura" We would like to welcome our newest test rig, an EELPRAAX-130 model christened "Laura." Laura is a twin to the first 4th generation test rig we built and sold earlier this year and will provide additional capacity at our testing facility in Aachen.The 4th
In recent weeks, we have been updating our oldest test rigs, built from 2010 onwards, to the latest technological level. These upgrades will improve not only our measuring capabilities and software control, but also reduce our electrical needs. This increased efficiency is due on the one hand to optimized pipe
We are once again offering “Basics of Bearing Technology,” “Bearing Supplier Development,” and “Failure Analysis.” We are very excited to be adding an all new session on failure analysis, “Additional Causes for Failure.”
Winter Session: January – April (registration open)
Spring Session: April – July (registration open)
Fall Session: September – December
Basics of Bearing Technology
This seminar provides basic knowledge of bearing technology for the design of bearing arrangements, their lubrication, and lifetime calculations.
Identifying and understanding the root causes of failures is necessary in order to initiate the required countermeasures. This seminar shows, based on practical examples, how damage characteristics can be identified and which conclusions they lead to.
When scientific research aims to break down the existing limits of machine elements, the associated equipment must meet the highest demands. Professor Kirchner and his team at the Technical University of Darmstadt (TUD) intend to use the electrical properties of rolling contact bearings for various purposes, including as sensors. This endeavor poses two particular challenges: measuring the bearing’s impedance at high frequency and understanding how the associated high frequency electric currents might impact bearing life. For this purpose, Elgeti Engineering GmbH built a special test rig which is capable of applying and measuring high frequency electric currents and voltages on all four of its stations.
The first research results were announced at the BearingWorld International Conference in October 2020. We are very pleased to share the associated article and are proud to support the highest level of academic research. Many thanks to Georg Martin, Tobias Schirra, and Prof. Dr. Eckhard Kirchner for the excellent collaboration and good luck with the further research!
When selecting a bearing supplier for industrial machinery, one typically needs more than just a bearing. In fact, what one really needs is a three-tiered service consisting of application engineering, the bearing itself, and preventative maintenance services such as diagnostics and condition monitoring. Operators of industrial plants such as steel mills and tire factories in particular rely on these services when working with the premium manufacturers.They appreciate their advice before buying and know they are in good hands if a problem were to arise.In collaboration with competent engineering companies, however, independent bearing distributers can meet or even outperform this level of customer service. The strength of bearing distributers is finding cost-efficient and reliable solutions while after-sales-services like preventive maintenance can generate further profitable business.
Es gibt verschiedene Gründe Wälzlager zu prüfen, wie zum Beispiel die Erstfreigabe eines Lieferanten, die regelmäßige Qualitätskontrolle, oder eine schnelle Abnahmeprüfung. Das "warum" ist der Anfang, aber das "wie" ist auch eine relevante Frage. Es ist wichtig zu verstehen, welche Teststrategien es gibt, welche für die Situation angepasst sind, sowie die technischen Fähigkeiten der Prüfmittel. Dieser Artikel verschafft einen Überblick über wann eine Prüfung angemessen ist, welche Methoden es gibt, und die Unterschiede zwischen den verschiedenen Prüfständen die es auf dem Markt gibt.
