ACTUATORS 1 ACT-27 For further information www.norgren.com Improved load carrying qualities Ecology seal improves load dampening Alignment coupler installed in tooling plate for self-alignment of cylinder rod to tooling plate connection prevents binding. Decel-Air Cushions Norgren's Decel cushioned cylinder was designed for applications where high velocity, low mass, material function or machine function is required, and where the kinetic energy to be absorbed during cushioning exceeds the parameters of standard cylinders equipped with Ecology piston seals and fixed or adjustable cushions. Decel cushions employ longer-than- standard air cushions to assist our Impact Dampening Piston Seal. *The weight of the cylinder piston has been deducted from the figures shown above. Note: The use of FPM Seals limits the absorption of the impact dampening seals by 50%. NOTE: The weight of a tooling plate, guide rods, and 1 extend and 1 retract stop collar has been added. (Guide rod weight is basd on a 6.0" stroke cylinder.) Energy Absorption Capacity of the Impact Dampening Seals *Usable Pounds Stoppable at the Following Piston Speeds This chart features the energy absorption capacity of the impact dampening piston seals with Non-Adjustable cushions.
