Catalog HY08-1130-3/NAApplication ChecklistMedium Duty Hydraulic CylindersSeries 3LApplication ChecklistThe following checklist should used to select the best possible cylinder for a given application. Additionalinformation can be referenced in the following pages to help assist in this process. In the event that you haveadditional questions or concerns, or if more information is required, please contact your local Parker distributor orour customer service representatives for assistance.1. Establish the system requirements. Series 3L How heavy is the load to be moved? What is the nominal operating pressure of the system? How far does the load have to move? What is the speed at which the load will move? What is the fluid type and the temperature to which the cylinder will be exposed?2. Mounting Style .Page 7 Determine the best mounting style for the application.3. Cylinder Bore and Operating Pressure.Page 62 Review the theoretical push and pull force for a given bore size to determine.4. Piston Rod .Page 71 Determine what rod size will be required to avoid buckling. Determine if a single or double rod cylinder is required. Determine the rod end style and rod end thread. Will stop tubing be required?5. Piston Seals .Page 5 Determine the best seal type for your application. Select the proper seal type and configuration for the application. Select the proper seal to assure fluid and temperature compatibility.6. Cushioning .Page 74 Determine if cushions are required to safely stop the load.7.
