This application uses an adiabatic model, which factors in the increased internal temperature generated by friction. The temperature increase due to friction causes higher pressure rise. Taking these real-world values into account during tool design can prevent unexpected challenges when the products are used in high production environments. For general reference, DADCO’s standard product catalogs use an isothermal model, which assumes no change in temperature during use, this matches the Industry Standard used in the nitrogen gas spring industry.

Part number denotes model and force based on DADCO product details and operating specifications. Refer to OEM standard for specific part number and operating guidelines. The calculated values are estimates for current revision DADCO products based on normal operating conditions. Calculations provided may differ from product literature recommendations based on rounding. Excess side loading forces, contamination, misalignment and other die construction factors may increase operating temperature. Attachment mass assumes balance load and actuation force. Do not exceed the ram velocity per lifter. This SOFTWARE is distributed for your convenience, but without any warranty.
