Solution
As extremely high forces act on all components in the medical chair, especially the central bearings at the upper end of the chair legs, a particularly robust solution was required.
The manufacturer ultimately opted for
iglidur plastic bearings, which are used in three different types at a total of six points in the device.
Compared to the originally planned ball bearings, the iglidur bearings have three specific advantages that were decisive here:
The bearings are designed for very high loads and work reliably and safely under these circumstances.
They are also exceptionally lightweight. In order to ensure the easiest possible handling, great attention is often paid to the weight of medical equipment. The lightweight plastic bearings make a decisive contribution to this goal.
Last but not least, Liftup was also able to save on purchasing costs compared to conventional ball bearings.
