A bearing arrangement, which is typically used to support a rotating shaft, generally requires two bearing supports – one at each end of the shaft. Depending on the requirements, such as stiffness or load directions, a bearing support consists of one or more bearings. Typically, the purpose of a bearing arrangement 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 arrangements can be designed:
- a locating/non-locating bearing arrangement
- an adjusted bearing arrangement
- a floating bearing arrangement
Bearing arrangements 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 arrangements, contact the SKF application engineering service.
