CH,CC,CB - Adjustable Cushions
Available only on DAN, DAP, and DAD models.
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.

* When the UB and PS options are in combination on an 1-1/16" bore, double rod end, only the

bumper length should be added. All other models and bore sizes should add the UB length and

the PS length together.

* When the UB and PS options are in combination on an 1-1/16" bore,

double rod end, only the bumper length should be added. All other

models and bore sizes should add the UB length and the PS length

together.

** Ecology piston seal adds .375" to the overall length when combined

with PS option on the 1-1/16" bore DRD model only.

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.

PL(__) - Alternate Port Location
Designate location on head and cap

respectively. For example: L(12) =

Head port location 1, and Cap port

location 2.

PC - Side ported end cap (DAN and SAN models only)
Port will be on the side of the end cap and in line with the head

end port. Overall length of the cylinder will increase.
Change in overall length due to the PC option.

M1,M2,M3,M4 - Switch rail mounted and position
Switch rail will be mounted in position #1 for M1

option, Position #2 for M2 option, etc. Must also

reference the PS option in the cylinder model

number to receive a magnet on the piston.
A band style swtich bracket can be ordered as a

separate item instead of the switch rail. See switch

section for band style bracket information.
Switches ordered as separate items.
FT(__) - Female thread
Specify thread type in parentheses. Female rod

thread available on 1-3/4", 2", 2-1/2", 3" bores.
