It is s suitable for parts of which the radial size is limited.The surface of shaft journal fitted with it is acted directly as rolling surface. It is requested that the surface hardness be no less than HRC60, surface roughness, no more than 0. 63um. This kind of full complement bearing, with inner ring or without inner ring, does not limit the axial shift of shaft and housing.
