ABSTRACT:
An adjustment method and apparatus to derive a pressure and measure for the securement force and alignment of flanges, couplings, bearings, headers, and securement bolts or nuts, where at least one member is moveable in relationship to another member such as a spindle nut retaining a wheel hub and the hub's inner and outer bearings upon a spindle, the spindle nut having affixed upon or embodied within, one or more axially affixed pressure calibration instruments to sense an axial pressure, and integrated with a corresponding axial micro measurement, to identify an exact pressure reference point from which is accomplished a desired securement force, the desired securement force being either satisfied or further accomplished by a specified increment of tightening of the securement device, thusly achieving dimensional stability of the structure. The precise method of the pressure calibration instrument provides an unequaled speed of adjustment and simplicity, sets new standards in securement and stress related safety, and introduces an exacting science to alignment, securement, and bearing adjustment.
