An actuator includes a ram structure slidably mounted within a cylinder structure bore and defines with the cylinder structure a gap therebetween. A fluid passageway structure in the ram structure defines a path for fluid to flow through the ram structure and includes an outlet in a sidewall of the ram structure. A cushioning seal located between the ram structure and the cylinder structure can engage the ram structure and a cylinder cap during ram structure extension such that the seal substantially closes off a first portion of the gap extending from the seal toward an open end of the cylinder structure. The cushioning seal can move during ram structure retraction in a direction of ram structure retraction such that fluid flowing out of the ram structure sidewall outlet, when the outlet is in the gap first portion, flows between the seal and the cylinder cap.
