Single acting, Spring extend Data 1 Bore Size Selection Note) Avoid applying a load on the cylinder as much as possible, because the value of the output force of a cylinder at the retraction side could be small. Note) Avoid loading the cylinder since the cylinder force at the extension side is a small value. Technical Data 1: Bore Size Selection 1822
