There are a lot of bearing types, from which the designer can choose the one that best suits his needs. Due to the variety of applications and the different influences on the bearing position, it is not, however, possible to give generally applicable rules here for the selection of the bearing type. When deciding on a specific bearing type, it is often necessary to weigh up several criteria.
The aim of the following descriptions is to assist the designer. They make reference to factors that play a primary role in the selection of the bearing type.
Product characteristics that can play a role in selection of the bearing type are, for example:
- the available design envelope
- the load values, load directions and the bearing arrangement concept (arrangement of the bearings)
- the speeds of the bearings
- the accuracy of the bearings
- the axial displacement capability of the bearing rings (non-locating bearing function)
- the compensation of misalignments
- quiet running
- the rigidity of the bearing arrangement
- the friction in the bearings
- the mounting and dismounting of the bearings
- the sealing of the bearings and of the bearing position
- the lubrication of the bearings.
