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.

Ex: 1-1/16 bore cylinder operating at 80 psi:
Force exerted on the extend: 0.89 x 80 = 71.2 lbs.
Force exerted on the retract: 0.81 x 80 = 55.2 lbs.

Available on bore sizes: 3/4”, 1-1/16”, 1-1/2”, 2”, 2-1/2”, 3”
Position #4 standard
UB - Bumpers
• Standard on 5/16”, 7/18”, 1-1/4”, and 1-3/4” bore sizes.
• The UB option will increase the overall length on all other bore sizes (see
chart for length changes).
• Single acting models will have one bumper on the piston side opposite the
spring.
• Bumpers are not included or available on ERP Ecology Seal models.
• When the HT high temperature option is ordered on these bore sizes, the
bumpers are omitted and may change the overall length of the cylinder
(except 5/16” bore, bumpers are not omitted).
• See “HT” Option below for further explanation of HT and UB in combination.

the PS length together.

HT - High Temperature Seals (Viton)
• For service up to 400°F
• Not available with RW rod wiper option.
• When ordered with the UB bumper option, bumpers will also be rated to 400°F.
• For cylinders where bumpers are standard, opting for HT will omit the
bumpers and may decrease the overall length of the cylinder (except 5/16”
bore). See chart below for length changes.
• For cylinders where bumpers are standard, if high temp bumpers are required,
reference both HT and UB in the model number. This will provide high temp
seals and bumpers and not change the overall length of the cylinder (except
5/16” bore).
• On the 5/16” bore, bumpers are always standard, and never omitted.
Additionally, high temperature bumpers are not available on this bore size.
As a result, with the HT option, the 5/16” bore cylinder is rated to 200°F.
