As for the full complement needle roller bearing with inner ring, the outer ring has the oil hole. The lubricating oil can be fed in from the oil hole. The outer ring has the double shoulders. As for the full complement needle roller bearing without inner ring, since the inner ring has no shoulder and cage, the inner ring, outer ring, complete set of needles can be mounted respectively. 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 0.63μm. This kind of full complement bearing, with inner ring or without inner ring, does not limit the axial shift of shaft and housing.
Since this kind of bearing has no cage, the needles rotate without correct guiding, they rub heavily against each other and the bearing has the low limiting rotational speed.
