ABSTRACT:
A hemispherical dynamic pressure bearing comprises a bushing in which a hemisphere/shaft unit is mounted with clearance, enabling the unit to move relative to the bushing between first and second terminal positions. In order to measure the size of the clearance, the bearing is inserted into a body, and a retainer disposed in the body is actuated for keeping the bushing stationary. An adjusting mechanism disposed in the body is actuated for displacing the hemisphere/shaft unit vertically relative to the bushing between the first and second terminal positions, wherein the hemisphere/shaft unit projects from an end of the bushing by first and second heights, respectively. Those heights are measured and a difference therebetween is determined, which difference corresponds to the clearance.
