ABSTRACT:
A spherical joint and bearing assembly utilizes a ball and socket arrangement between a connecting rod and a crosshead in a power reciprocating fluid pump. The connecting rod is spherically shaped and is held in a thrust bearing having a matching interior surface. A split retraction ring is held between the rear portion of the sphere and a shoulder in the crosshead. The result is an increased bearing surface and reduction in misalignment.
