• SKF Tapered Bearing Sets greatly reduce friction and increase load carrying capabilities. W.ec_corpid = '6601479'; Bearing Sizes. Split housings machined to tight tolerances, such as SKF plummer block housings, can be used for transition fits up to K7. Dimensional tolerances for bearing seats are dictated by the required fit. the interference fit is not sufficiently tight. A bearing ring mounted with a loose fit will creep on its seat when subjected to a rotating load, and this can lead to fretting corrosion and eventually wear. For rotating inner ring loads, this deformation can loosen the interference fit between the inner ring and shaft, causing the ring to creep on its shaft seat. The run-out of the seat is specified by the total radial run-out of the seat surface and the total axial run-out of the abutment (ISO 1101, 18.16).
