ABSTRACT OF THE DISCLOSURE A high pressure thrust bearing assembly having a rotatable runner ring mounted in sliding relationship on a plurality of flexible thrust plates, which in turn are resiliently supported on a plurality of spring subassemblies positioned between the thrust plates and an angular base member in the assembly, is characterized by having a plurality of Belleville spring discs mounted in each of the spring subassemblies. The spring discs are supported in coaxial relation on a screw, between a first and a second washernin each of the spring subassemblies, in a manner such that the spring discs are pre-compressed between the washers to bias them away from one another with a constant biasing force. Furthermore, the spring discs are arranged in cooperating pairs in the coaxial relationship so that the endmost discs have their respective concave sides abutting the closest washer thereto while the remaining pairs of discs are arranged to place the discs in alternately reversed relationship or in preselected parallel and series arrangements within given spring subassemblies thereby to selectively establish the stiffness of the spring subassemblies.
