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.
