HEAVY DUTY AUTOMATION CYLINDERS
ORDERING INFORMATION
LYNAIR SERIES “CS2” CYLINDERS
CHRYSLER CORP. MMAC-100 SPECIFICATIONS
A Model Numbering system for describing cylinder size and
variable construction features that are available for use in
“standard” cylinders is explained below.
This model number consists of Letter and Number Codes
which represent the desired choices between available variables which make up the cylinder construction details.
Cylinders may be ordered to include non-standard features
that cannot be identified in coded number terms. When special features are desired, clearly describe requirements with
a supplemental callout of details.
Cylinders manufactured to meet the requirements of this
Chrysler Corporation Engineering Standard are identical
to Series “CS2” models in design, but have certain dimensional differences affecting the mounting of some models.
Charted dimensions pertaining exclusively to these cylinders are given on page 83.
The model number form used to identify cylinder construction details also conforms to Chrysler Standards. This
model number, described below in detail, must be used
when ordering cylinders that are to meet this specific standard.
GENERAL SPECIFICATIONS
REQUIREMENTS OF CHRYSLER STANDARD
RATED FOR 200 P.S.I. AIR/1000 P.S.I. HYD. SERVICE
Standard Series “CS2” cylinders are constructed to be suitable for use with either air or hydraulic fluid as the operating medium.
OPTIONAL “CUSHION” FEATURE
Cushions, which decelerate the rod travel speed before
reaching the end of stroke position, are optional at either
one or both ends of all cylinders.
Use of cushions is not recommended when stroke length is
less than 3 inches.
PORT POSITION OPTIONS
Operating ports may be specified to be on any two of the
four numbered side positions without added cost. The
desired port positions should be included in the model number information submitted.
Standard port locations are as follows:
11/ 2 thru 21/ 2 Bore - Port location #1.
31/ 4 thru 10 Bore - Port location #2 and #4.
Cylinders will be provided with ports in these positions
unless otherwise specified in order details.

NOTE: INCLUDE “DASH” MARKS ONLY AS SHOWN.
RATED FOR 200 P.S.I. AIR/1000 P.S.I. HYD. SERVICE
Cylinders are constructed to be suitable for use with either
air or hydraulic fluid as the operating medium.
Air operated cylinders are designated “MMAC” models,
while those for hydraulic service are termed “MMHC”
units.
Exterior dimensions of “MMAC” and “MMHC” cylinders
are identical.
USE OF “CUSHION” OPTION
Cylinders are to be “non-cushioned” when the stroke length
is 2 inches or less.
When the stroke length exceeds 2 inches, all cylinders are to
include “adjustable cushions on both ends”.
STROKE LENGTH RESTRICTION
Cylinder stroke lengths are to be ordered in full inch increments only.
ROD END THREAD SPECIFICATIONS
Cylinder piston rod is to have a male threaded rod end equal
to Lynair standard Style 1.
STANDARD PORT LOCATIONS
All cylinders are to have two ports in each end with the preferred location being on sides #2 and #3.
If alternate port locations are desired, positions #1 and #4
may be specified.
