In most cases, the inner surface of the inner ring of the roller bearing or the inner surface of bushings is ground by the roll type centerless internal grinder.<BR>In this case, the work is held by 3 rolls and ground. Thus, the roll pressure imposed rdially on the work will restrict the vibration of work and, as well, will provide the work with axial thrust in the direction of the support. In auto-gaging, the gage pressure will work in the direction counter to the thrust and, if the work moves minutely in the direction of the axis, eventually working accuracy will be greatly affected adversely. As correlativity between the gage pressure and dimension accuracy exists, the correlativity between the roll pressure and thrust was sought for in order to establish the gage pressure.
