  "textContent": "A linear electric machine includes a shaft, a primary piston assembly operably coupled with the shaft, a stator assembly supporting the shaft and housing a load device, and a bearing assembly supporting an end of the shaft. The bearing assembly includes a bearing housing and a fluid bearing within the bearing housing. The bearing housing includes an opening for receiving the shaft therethrough. The linear electric machine also includes a secondary piston assembly formed integrally with the shaft and at least a portion of the bearing assembly for providing fluid to the bearing assembly.",
