NUtype and Ntype bearings allow shaft move relative to housing in a definite range. They can suit relative position change of shaft and housing caused by heat expansion or mounting error, and they are very suitable for free end bearings. They can not limit axial displacement of shaft and housing, and can only be subject to radial load.
