摘要：A bearing, which may be used to mount a swing arm on the frame of a computerdisk drive, has an outer race provided with two raceways of arcuate cross section. Eachraceway has a row of raceway balls located along it. The raceway balls of each row, inturn, surround and bear against a separate pivot ball. The two pivot balls are greater in

diameter than the circles described by the innermost areas of the rows of raceway balls,so that the pivot balls when urged together bear against the raceway balls of the tworows and urge them against their raceways. The force which urges the two pivot ballstogether may derive from spring-loaded arm engaged with one of the balls.
