An additional intermediate bearing is often included in the shaft connection of high-speed test beds.
ERNST offers a wide range of bearing positions according to the required speedrange as well as the required torque.
Corresponding advice from the design department is recommended for the technical assessment of the respective application.
In this regard, the holistic approach – from the concept to in-house production and pre-commissioning at ERNST – is a particular strength in the assessment of technical feasibility.
It is also possible to convert existing intermediate bearings to reach individual requirements or customer wishes.
