Airtec Series ZD ISO 6432 Pneumatic Cylinders
Airtec Series ZD pneumatic cylinders form part of Airtec's ISO 6432 round-cylinder platform and include standard and specialist configurations used across industrial machinery. The ZD code is particularly important in replacement work because additional letters within the Airtec ordering system identify features such as magnetic piston sensing, adjustable cushioning, anti-rotation and through-rod construction.
Cylinder Warehouse therefore keeps Series ZD as its own collection rather than forcing every ZD product into one of the more specific derivative ranges. If the original Airtec MPN is still visible on the machine, use the complete code when selecting a replacement.

Understanding the Airtec ZD Coding Family
Airtec's historic and distributor ordering data shows that the ZD platform uses additional characters to identify important mechanical and operating features.
This coding relationship is why two Airtec pneumatic cylinders that look very similar externally can perform different functions. The complete manufacturer code should be treated as part of the technical specification.

Specialist ZD Versions Matter During Replacement
The current Cylinder Warehouse data includes products such as ZD 25/160-V as well as stainless/high-temperature ES-V configurations. These suffixes should not be removed when sourcing a replacement because they identify material or seal specifications that may have been selected for a particular machine environment.
For example, verified ZD 25/160-V data specifies FKM seals and no magnetic piston, while the standard Airtec ZD platform can use different sensing and material configurations. The complete MPN is therefore more reliable than identifying the pneumatic cylinder from bore and stroke alone. :contentReference[oaicite:1]{index=1}
Standard Stainless Tube or ES Stainless Construction?
Standard verified ZD products use a stainless-steel cylinder tube with aluminium end components. The ES versions go further by using stainless steel for additional cylinder components.
Verified Airtec ZD ES-V data specifies 1.4301 stainless steel for the head, foot and tube together with a 1.4436 stainless-steel piston rod. That makes an ES product materially different from a standard ZD pneumatic cylinder even where the nominal bore and stroke are identical. :contentReference[oaicite:2]{index=2}
Verified ZD Examples in the Cylinder Warehouse Catalogue
The current Airtec catalogue includes live or reviewed examples such as:
-
ZD 12/100 — 12 mm bore × 100 mm stroke ISO 6432 pneumatic cylinder.
-
ZD 25/160-V — 25 mm bore × 160 mm stroke FKM configuration.
-
ZD 20/400 ES and ES-V products — stainless specialist versions currently requiring individual data checks before publication.
The Cylinder Warehouse audit confirms ZD products are classified as ISO 6432 pneumatic cylinders, while several ES-V items remain deliberately in draft until their outstanding technical fields are confirmed. :contentReference[oaicite:3]{index=3} :contentReference[oaicite:4]{index=4}
Choose the Specific ZD Family You Actually Need
If the cylinder code contains additional letters, use the dedicated collection wherever possible:
This gives buyers a faster route to the actual mechanical configuration fitted to the machine rather than browsing a mixed catalogue of visually similar pneumatic cylinders.
Questions That Matter When Ordering Airtec ZD
Why does Cylinder Warehouse keep ZD separate from ZDM?
Because the Airtec ordering code uses additional characters to define important options. ZDM specifically identifies the magnetic branch of the wider ZD platform, while products carrying only ZD or specialist suffixes can have different sensing, material or seal arrangements.
What does -V mean on an Airtec ZD pneumatic cylinder?
Verified Airtec data uses -V for an FKM-sealed high-temperature configuration. On the confirmed ZD 25/160-V product, the specification also states that there is no magnetic piston.
What does ES mean?
ES identifies a more extensively stainless-steel construction. Because the materials differ from a standard ZD pneumatic cylinder, preserve the ES designation when replacing an existing product.
Can I substitute a ZD with any ISO 6432 pneumatic cylinder?
ISO 6432 provides important dimensional compatibility, but it does not guarantee that sensing, cushioning, rod arrangement, material specification or temperature capability are identical. Compare the complete product configuration before substitution.
Where can I compare Airtec ZD alternatives?
Use the Airtec pneumatic cylinder hub for other Airtec series, or browse ISO 6432 pneumatic cylinders across manufacturers where a cross-brand replacement is being considered.
