pad thrust bearing of equal capacity showed that the tilting pad thrust bearing, at only1/4 the size, had 1/7 the area but operated successfully with only 1/10 the frictional drag of the horseshoe bearing. In 1896, inspired by the work of Osborne Reynolds, Albert Kingsbury conceived and tested atilting pad thrust bearing. Accordingto
