ABSTRACT:
The present invention relates to a method of measuring a clearance of a hub bearing for vehicles. A hub is fixed to a lower jig when a row of hub-side balls is disposed and an outer ring is disposed on an outer periphery of the hub and a row of inner ring-side balls and an inner ring are disposed. A press-fit jig is contacted to the inner ring and a load of less than 5 kgf is applied to an outer surface of the outer ring to prevent its vibration and movement. A gauge is installed to a portion of the outer ring. The inner ring is gradually press-fitted by the jig. An amount of press-fit of the inner ring is measured from when the gauge begins to move when press-fitting of the inner ring is completed. The amount of clearance is simply measured.
