Airtec TM Stainless Steel Pneumatic Cylinders
Airtec Series TM pneumatic cylinders are stainless-steel ISO 15552 actuators developed for machinery where material selection and environmental resistance are as important as bore, stroke and mounting dimensions. The verified TM ES construction uses stainless steel for the cylinder head, base and tube, together with a 1.4401 stainless-steel piston rod.
The range is double acting, incorporates a magnetic piston for position sensing and includes adjustable pneumatic end cushioning. Bore sizes from 32 to 125 mm and stroke capability up to 2000 mm make TM suitable for everything from compact machine movements to long-travel industrial actuation.
For a conventional aluminium-profile ISO 15552 actuator, compare Airtec XL pneumatic cylinders. You can also browse ISO 15552 pneumatic cylinders across manufacturers or return to the complete Airtec pneumatic cylinder range.
Stainless Construction Where a Standard Profile Cylinder Is Not Enough
The reason to specify Airtec TM is its construction. A standard aluminium pneumatic cylinder may be perfectly suitable inside normal factory machinery, but applications exposed to moisture, regular cleaning or more demanding industrial environments can place greater emphasis on the materials used around the actuator.
Verified TM ES pneumatic cylinders use 1.4301 stainless steel for the head, base and cylinder tube and 1.4401 stainless steel for the piston rod. This is substantially different from simply fitting a stainless piston rod to an otherwise aluminium cylinder.

These bore-dependent connections are another reason to use the complete Airtec manufacturer part number when sourcing a replacement rather than selecting a pneumatic cylinder from bore and stroke alone.
Adjustable Pneumatic End Cushioning
TM pneumatic cylinders include adjustable end-position cushioning, allowing the exhaust flow near the end of the stroke to be tuned to the moving load and operating speed.
This becomes increasingly valuable on larger-bore or long-stroke pneumatic cylinders where the piston and attached mechanism can carry significant kinetic energy. Controlled deceleration can reduce impact, noise and mechanical stress as the cylinder reaches the end of travel.
Magnetic Position Sensing
Airtec TM uses a magnetic piston as part of the verified standard construction, allowing compatible cylinder switches to provide non-contact position feedback.
This means the stainless-steel actuator can be integrated into automated machinery without sacrificing piston-position monitoring, making it suitable for sequenced production equipment as well as straightforward mechanical movement.
Standard and Special Stroke Lengths
Airtec documentation lists standard TM ES strokes including 25, 50, 80, 100, 125, 160, 200, 250, 320, 400 and 500 mm.
Customer-specific strokes from 1 to 2000 mm are also documented, subject to the allowable buckling load of the piston rod. This gives TM considerable flexibility where a standard catalogue stroke does not match the existing machine.
TM for Replacement Applications
Series TM is particularly valuable for exact replacement work because an installed stainless pneumatic cylinder may have been chosen specifically for its materials rather than simply its ISO dimensions.
For example, TM 40/250 ES identifies a 40 mm bore × 250 mm stroke ISO 15552 pneumatic cylinder with a G1/4 pneumatic connection, M12 × 1.25 piston-rod thread and the verified stainless TM ES construction.
Replacing it with a standard aluminium ISO 15552 pneumatic cylinder may physically solve some dimensional requirements while removing the material specification that led to the original TM being selected.
Airtec TM or XL?

General machine automation, sensor integration and broad ISO 15552 replacement |
| TM |

Applications where corrosion resistance and stainless materials are required |
Both families use ISO 15552 dimensional principles, but they address different operating environments. Where the existing machine uses TM ES, preserve the stainless specification unless the application has been technically reviewed.
TM and Cross-Brand ISO 15552 Alternatives
ISO 15552 gives engineers a useful dimensional framework when looking for alternatives, but the standard does not automatically make a conventional cylinder equivalent to Airtec TM.
If a cross-brand replacement is being considered, compare the ISO 15552 pneumatic cylinder range while checking material grade, cushioning, sensing, port size, piston-rod thread and environmental requirements as well as bore and stroke.
Airtec TM Purchasing Questions
Is Airtec TM definitely ISO 15552?
Yes. Verified Airtec and Landefeld technical data identifies TM as a double-acting ISO 15552 pneumatic cylinder family.
What does ES identify on a TM pneumatic cylinder?
The verified TM ES products are the stainless-steel versions, using 1.4301 stainless steel for the head, base and cylinder tube and 1.4401 stainless steel for the piston rod.
Does Airtec TM have adjustable cushioning?
Yes. Verified TM ES specifications include adjustable pneumatic end-position cushioning as well as a magnetic piston.
How long can a TM pneumatic cylinder stroke be?
Airtec documentation provides customer-specific stroke lengths from 1 to 2000 mm, subject to piston-rod buckling and application limits.
Can I replace TM with Airtec XL if the bore and stroke are identical?
Not on bore and stroke alone. XL uses a different construction and TM ES has a stainless-steel material specification. Confirm mounting dimensions, environment, rod connection, port, cushioning and sensing before changing series.
Is TM suitable where stainless construction is a key requirement?
Yes. That is one of the defining reasons to select the verified TM ES range. The head, base and cylinder tube are 1.4301 stainless steel and the piston rod is 1.4401 stainless steel.
