For this, a tight interference fit is required between the inner ring of the bearing and the shaft.
Unfortunately, because most bearings are unable to handle both axial displacement and structural misalignment, it has not been feasible for hearings to be installed with an interference fit on both the inner and outer ring.
This enables all four bearing rings to be mounted with an interference fit that eliminates fretting corrosion and creep.
Interference fits work by forcibly pressing and/or heating and cooling the components.
The methods traditionally used to facilitate the connections of shafts and hubs can be classified into three types: material fit, which uses welding, soldering, or adhesives; positive form fit, which uses keys, splines, and polygon-shaped hubs or shafts; and friction fit, which uses interference fit, tapered forms, and shrink disks.
