Peninsular’s unique and improved 100 % air tight adjustable cushioning system contains advanced engineering features specifically not often found in conventional steel air cylinders and frequently not found in other commercially manufactured aluminum cylinders. Our industry proven and tested cushioning system will usually provide about four times the cylinder life as compared to a cylinder that is not cushioned, in those applications that contain stroke lengths in excess of three to four inches. Heavier loads and long stroke destructive applications are best suited for the use of our improved cushion system. Because of our cushion system design and other important internal engineering features, our cylinders have significantly outlasted the competition in these destructive type applications. The Peninsular design completely eliminates the springs and ball bearings usually associated with conventional cylinder cushioning systems, thus, reducing the spare parts required to support our line of air cylinders. In addition, the same cushion seal is used at both cylinder ends further reducing cylinder spare part inventories. Pneumatic cylinder adjustable cushions are internally designed features, by each cylinder manufacturer, that prevent the cylinder piston from slamming into the inside surface of the end cap at the end of the extended and retracted cylinder stroke. 100% air tight cushions significantly enhance the cushioning system, and thereby increase the efficiency of the cushion effectiveness. By reducing the force of the impact of the piston slamming into the cylinder end cap (with 100% air tight effectiveness) cylinder tie rod and piston rod failure due to fatigue is all but eliminated. Our adjustable cushion design also contains a captive cushion adjustment screw, a safety feature that prevents injury to anyone who may be loosening the cushion adjustment screw to control the end-of- stroke travel speed of the piston rod. The drawing below further illustrates how the Peninsular Model MH and LM cushion system works as compared to conventional cushion system designs. Our model MH and LM pneumatic cylinders contain spare parts that are completely interchangeable from one cylinder model to the other, thus further reducing cylinder spare part inventories in those facilities which utilize both Peninsular aluminum and steel air cylinders. |
