A bearing system, which is typically used to support a rotating shaft, generally requires two bearing arrangements – one at each end of the shaft. Depending on the requirements, such as stiffness or load directions, a bearing arrangement consists of one or more (matched) bearings. Typically, the purpose of a bearing system is to support and locate the shaft radially and axially, relative to stationary components, like housings. Depending on the application, loads, requisite running accuracy and cost considerations, various bearing systems can be designed:
- a locating/non-locating bearing system
- an adjusted bearing system
- a floating bearing system
Bearing systems consisting of a single bearing that can support radial, axial and moment loads, e.g. for an articulated joint, are not covered here. For information about these bearing systems, contact the SKF application engineering service.
