Technical information & FAQs

Airtec Series ZDM Pneumatic Cylinders

Airtec Series ZDM pneumatic cylinders are slim round-body actuators built for machinery where installation space is limited but a durable stainless-steel cylinder tube is preferred. The ISO 6432 format keeps the actuator compact, while the magnetic piston allows position sensing without adding bulky external mechanisms.

The ZDM range appears across multiple bore and stroke combinations in the Cylinder Warehouse Airtec catalogue, making it useful for machine replacement, light automation, packaging equipment, fixtures and compact industrial mechanisms. Where a larger profile actuator is required, browse the Airtec XL pneumatic cylinder range.

For other small-format Airtec options, return to the Airtec pneumatic cylinder hub or compare the wider ISO 6432 pneumatic cylinder range.

Why Choose Airtec ZDM?

Series ZDM gives machine builders a narrow cylindrical actuator rather than the larger rectangular body used by compact and ISO 15552 pneumatic cylinders. This can make installation easier between guards, framework, tooling and adjacent components.

The stainless-steel tube and piston-rod construction also make ZDM a robust choice for repetitive industrial movement, while the magnetic piston supports non-contact position sensing on automated machinery.

A Compact Pneumatic Cylinder for Tight Machinery

The main reason to choose ZDM is packaging efficiency. Its round ISO 6432 body takes up less external space than a larger profile pneumatic cylinder, making it useful where the actuator has to fit close to frames, conveyor structures or other machine components.

This compact format is especially valuable in retrofit work, where the existing installation envelope is already fixed and changing surrounding brackets or guarding would add unnecessary work.

Broad Bore Coverage Within the ZDM Range

The current Cylinder Warehouse Airtec catalogue contains ZDM pneumatic cylinders from very small 8 mm bore units through to 25 mm versions. This gives the family a useful spread of output force while keeping the same slim round-cylinder concept.

Browse by bore where required:

Magnetic Position Sensing

Verified Airtec ZDM product data identifies the range with magnetic piston construction. This allows compatible cylinder switches to detect piston position without mechanical contact, which is useful for extension/retraction confirmation and machine sequencing.

For example, Airtec ZDM 16/60 is specified with magnetic piston construction, stainless-steel tube and piston rod, NBR/PUR seals and a maximum working pressure of 10 bar. :contentReference[oaicite:2]{index=2}

Stainless-Steel Construction

Verified ZDM product data specifies an anodised aluminium head and foot together with a stainless-steel tube and stainless-steel piston rod. This gives the range a durable industrial construction without moving into a much larger or heavier actuator format. :contentReference[oaicite:3]{index=3}

Selected ZDM configurations are also available with FKM seals for temperatures up to 150°C, although those versions do not necessarily retain the same magnetic specification and should be ordered deliberately. :contentReference[oaicite:4]{index=4}

ZDM Standard and ES Variants

The Cylinder Warehouse catalogue contains both standard ZDM codes and ES variants, including examples such as ZDM 20/160 ES and ZDM 25/400 ES. The suffix should be preserved when replacing an existing pneumatic cylinder rather than treated as cosmetic, because it identifies a specific Airtec catalogue configuration. :contentReference[oaicite:5]{index=5}

If the original MPN is still visible, use the complete Airtec code when ordering. This is safer than identifying the actuator only from physical dimensions.

Related Airtec Pneumatic Cylinder Ranges

Series ZDM sits alongside several related Airtec small-cylinder ranges in the Cylinder Warehouse catalogue. Once those series pages are created, this page should link directly to:

Airtec ZDMK pneumatic cylinders
Airtec ZDMO pneumatic cylinders
Airtec ZDPM pneumatic cylinders
Airtec ZDPMK pneumatic cylinders
Airtec ZEM pneumatic cylinders

These should remain separate collection pages because their series values and product configurations are distinct within the Airtec catalogue.

Airtec ZDM Buying Questions

I already have a ZDM code on my machine. Should I replace it with Airtec HM?

Airtec now lists HM as an alternative to some older ZDM products in certain markets, but that does not mean every ZDM can be replaced automatically. Check the exact bore, stroke, mounting, rod thread, port and operating options before changing series. :contentReference[oaicite:6]{index=6}

Does a ZDM pneumatic cylinder use a magnetic piston?

Verified standard ZDM examples do. This allows compatible proximity sensors to monitor piston position without mechanical switches contacting the moving rod. :contentReference[oaicite:7]{index=7}

Are ZDM pneumatic cylinders only available in 16, 20 and 25 mm bores?

Older Airtec technical tables prominently show 16, 20 and 25 mm stainless ZDM versions, while the Cylinder Warehouse catalogue also contains ZDM products in 8, 10 and 12 mm bore. The exact MPN should therefore be used when selecting from the full catalogue. :contentReference[oaicite:8]{index=8}

Can I use a ZDM in a high-temperature application?

Selected FKM-sealed versions are specified for temperatures up to 150°C. The seal and sensing specification should be checked carefully before replacing a standard ZDM with a high-temperature variant. :contentReference[oaicite:9]{index=9}
