mounting arrangements when selecting a mounting arrangement for rbc thin section ball bearings you must first consider the loading condition a duplex pair of angular contact bearings may be used for combined loading moment loading or heavy thrust loading combination a and c-type a and x-type or c and x-type bearings are common mounting arrangements two x-type bearings should never be mounted on the same shaft there may be many different bearing arrangements for carrying the same load some typical mounting arrangements are shown below reversing loads the duplex pair of a-type bearings offers several configurations for reversing loads either back-toback b-type or face-to-face f-type should be used the f-type mounting method demonstrates reversing thrust load combined radial and thrust loads are shown on the b-type configuration both of these methods can be used for heavy radial loads combined thrust and radial loads or moment loads shim here for proper axial preload radial load radial load reversing thrust load f-type configuration radial load heavy radial loads the c-type bearing is designed primarily for heavy radial loads two bearings can be installed on the same shaft as shown by axially fixing one bearing and allowing the other to float this configuration allows differential expansion between the housing and shaft such as caused by temperature difference without adding axial stress to the bearings although the c-type bearing is designed for radial loads they can withstand moderate thrust moment and reversing loads reversing thrust load shim here for proper axial preload b-type configuration 32 rbc bearings are made in the u.s.a.
