Abstract: A wedge bearing assembly includes a housing having a bore therein. A reciprocating rod having a polygonal cross-section extends through the bore. A ring is mounted to the housing and includes a plurality of sloped surfaces adjacent to a center polygonal opening. A plurality of wedges are disposed against a respective one of the plurality of sloped surfaces, each of the plurality of wedges having an edge disposed against the rod. A washer is disposed against the plurality of wedges and an annular spring is disposed against the washer. A tension ring is disposed against the annular spring.

Abstract: A seal system includes a housing defining a bore having an inner bore surface. A rotating shaft is rotatably received in the bore and includes a recessed annular groove. A seal body has an unassembled form having a ring shape, wherein in an assembled state the seal member is received in the annular groove of the rotating shaft with the seal member flipped with a first side surface facing radially inward toward the annular groove and a second side surface facing radially outward toward the bore, the first side surface along a cylindrical outer diameter surface being lifted off of a bottom surface of the annular groove so that the second side surface along the outer diameter surface engages the inner bore surface while the second side surface along an inner diameter surface is spaced from the inner bore surface.
