Abstract
A submersible pump assembly has a seal section between the motor and the well fluid pump, the seal section having a housing, a shaft and a thrust bearing unit. The thrust bearing unit includes a thrust runner mounted to the shaft that rotates against a thrust bearing base fixed in the housing. An annular, metal thrust runner wave spring has an inner diameter surface in contact with the shaft and an outer diameter surface in contact with the runner bore. The wave spring has a transverse width between the inner diameter surface and the outer diameter surface that is elastically deflectable, exerting an inward bias force against the shaft and an outward bias force against the runner bore.
