Bearings

General information

A bearing is a drive technology machine element that serves to support shafts and other rotating parts in such a way as to ensure the rotating movement with as little resistance as possible and with the most accurate guidance. The part of the shaft that fits into the bearing is the shaft pin. In some cases, the bearings have to absorb significant forces. These forces can come from the weight of the rotating part, rotating and alternating mass forces resulting from unbalance, and other effects occurring during the operation of the machine (vibration, media pressure, electromagnetic forces, forces from the tool in cutting machines, etc.).

 

The forces can load the bearing radially or/ and axially. In addition to mechanical stresses, it must also withstand the heat load from friction, without significant deterioration of the running characteristics.
