A bearing assembly is provided which includes an annular support member and
a plurality of thrust bearing elements coupled to and distributed about
the face of the support member. The thrust bearing elements are adapted to
receive and support an axial load of a rotating member such as a thrust
collar on a shaft. An annular distribution ring is mounted to the face of
the support member for restricting motion of the thrust bearing elements.
A distribution passage is formed between the distribution ring and the
support member in such a manner that the distribution passage carries
fluid to and across each of the thrust bearing elements.
