A low friction alignment device designed for operation in unfavorable environments, such as high temperature furnaces or vacuum or where initial placement is poor, is constructed and operates as follows. A configuration of three ball bearings is used as the basis for this alignment device. Three precision balls 1 are mounted and contained within a retaining spider ring 2. A mounting plate 3 is available for mounting the ball and spider assembly to a fixture, work station or other device. A mating assembly 4 can be of a conical or spherical nature and attached to the mating detail of the fixture. The diameter of the mating assembly is precisely equal to the available diameter between the three floating balls.
