When hydraulic pressure is applied, the ram extends to apply force through the center opening. This design allows threaded rods or shafts to pass through while force is applied around them. The ram responds directly to pressure input and retracts once pressure is released. It is used during controlled service operations where straight force application is required. The OTC Tools 4121A enables centered force delivery during heavy-duty shop procedures.
