ACTUATORS 1 ACT-03 For further information www.norgren.com Roundline Ecology Piston Seal Option (ERP) The Ecology (Impact Dampening) Piston Seal option is available on select inch bore size Roundline cylinders in DAP, DAD, and DAN configurations. This option includes non-adjustable air cushions on both the extend and retract stroke of the cylinder. By including the Ecology Piston Seal option, cylinders can be specified based on weights of load being carried and speed of load. This is shown in the table below. Energy Absorption Capacity of the Impact Dampening Piston Seal This chart represents the energy absorption capacity of the Impact Dampening piston seals with standard Non-Adjustable air cushions. The values given are usable pounds stoppable at stated piston speeds. The figure above represents total stroke loss (both ends) for the pressure indicated for new cylinders. The impact dampening seals will take some compression set during operation of the cylinder and the stroke loss will decrease. To determine stroke loss for either head or cap divide the value shown by 2. Ecology Roundline Plus - ERP Model The ERP model is the cost effective answer to load deceleration and faster through cushion performance. Oil impregnated sintered bronze Rod Bearing provides exceptional rod support, and optimal cycle life Carbon steel Piston Rod for strength, smooth operation, and long life (stainless steel Piston Rod on 5/16, 7/16, 9/16 and all Double Rod cylinders) Lip-Type nitrile Rod Seal, pressure energized and wear compensating Head and Cap are solid aluminum alloy for strength and durability Solid aluminum Piston is strong yet lightweight for low inertia Lip-type nitrile Piston Seals are wear compensating for long life 304 stainless steel Cylinder Body with polished I.D. ensures smooth performance and outstanding life cycle 1 *Note: Single acting cylinders (not shown) use springs manufactured from music wire to provide millions of trouble free cycles.
