Technical information & FAQs

Airtec DSWPM Roundline Pneumatic Cylinders

Airtec Series DSWPM pneumatic cylinders are double-acting roundline actuators designed for industrial machinery that needs a traditional cylindrical body without moving to a square-profile ISO cylinder. The range combines an anodised aluminium head and base with a 1.4301 stainless-steel cylinder tube, hard chrome-plated piston rod and magnetic piston for non-contact position sensing.

DSWPM is available in 32, 40, 50 and 63 mm bore sizes and is particularly useful where a round-bodied pneumatic cylinder is preferred for machine layout, replacement compatibility or long linear movements. Airtec documents customer-specific strokes from 1 to 1000 mm, giving this family substantially more travel capability than many compact pneumatic cylinder ranges.

A Roundline Pneumatic Cylinder for Larger Bore Sizes

Many industrial round cylinders are concentrated around small ISO 6432 bore sizes. DSWPM extends the round-body concept into 32, 40, 50 and 63 mm diameters, allowing considerably greater pneumatic force while retaining a cylindrical tube construction.

This makes DSWPM useful for machine builders and maintenance engineers who want a conventional round pneumatic cylinder rather than the larger rectangular profile associated with many 32–63 mm industrial actuators.

32, 40, 50 and 63 mm Bore DSWPM Pneumatic Cylinders

Bore	Pneumatic Port	Piston-Rod Thread	Head Mounting Thread
32 mm	G1/8	M10	M30 × 1.5
40 mm	G1/4	M12	M38 × 1.5
50 mm	G1/4	M16	M45 × 1.5
63 mm	G3/8	M16	M45 × 1.5

Airtec's published dimensional data confirms that pneumatic connection size and mounting geometry change with bore, so a DSWPM replacement should be selected from the complete manufacturer part number rather than bore and stroke alone.

Long-Stroke Pneumatic Cylinder Capability

One of the strongest reasons to use DSWPM is stroke availability. Airtec publishes standard products at numerous lengths including 10, 25, 40, 50, 80, 100, 125, 160, 200, 250, 320, 400 and 500 mm, with customer-specific strokes available from 1 to 1000 mm subject to piston-rod buckling limits.

This makes DSWPM suitable for applications such as long transfer movements, gates, positioning mechanisms, handling systems and machine functions where a compact pneumatic cylinder would simply not provide enough travel.

Stainless-Steel Cylinder Tube

The DSWPM body uses a 1.4301 stainless-steel cylinder tube with anodised aluminium head and base components. This gives the actuator a durable smooth round construction while keeping the end components comparatively lightweight.

The piston rod is hard chrome-plated steel rather than stainless steel, which is important when comparing DSWPM with fully stainless pneumatic cylinders intended for more aggressive environments.

Magnetic Piston as Standard

The M within DSWPM identifies the magnetic-piston configuration, and Airtec lists magnetic sensing as standard for the series.

Compatible cylinder switches can therefore be added to provide non-contact position feedback for PLC-controlled machinery, sequencing and interlocking applications.

Understanding the DSWP Ordering Code

Airtec's catalogue shows that DSWP is the base round-cylinder platform and that additional characters identify important options:

Code	Feature
M	Magnetic piston — standard DSWPM configuration
V	Adjustable end-position cushioning
K	Through piston rod

This produces related configurations such as DSWPVM, DSWPMK and DSWPVMK. These should not automatically be grouped into standard DSWPM because the cushioning and rod arrangement materially change the pneumatic cylinder specification.

DSWPM or an Airtec XL Profile Pneumatic Cylinder?

DSWPM and Airtec XL pneumatic cylinders can overlap in bore and stroke, but they use very different body designs.

Airtec Range	Construction	Best Starting Point When...
DSWPM	Round stainless-steel tube	The machine uses a traditional round-body pneumatic cylinder or needs the DSWPM mounting format
XL	ISO 15552 aluminium profile	Standardised ISO 15552 profile mounting and integrated sensor grooves are required

For replacement work, these ranges should not be treated as direct substitutes purely because the bore and stroke match.

DSWPM or Airtec ZDM?

Airtec ZDM serves the smaller ISO 6432 round-cylinder market, while DSWPM provides the larger 32–63 mm roundline format.

This makes the two collections useful internal alternatives for customers who specifically prefer cylindrical pneumatic cylinder construction but require different bore ranges.

Example: Airtec DSWPM 40/400

DSWPM 40/400 is a 40 mm bore × 400 mm stroke double-acting roundline pneumatic cylinder with a G1/4 air connection. It uses the standard DSWPM stainless-steel tube, magnetic piston and hard chrome-plated piston rod construction.

That exact configuration is already live within Cylinder Warehouse, making the DSWPM collection useful both for general range navigation and direct MPN-led replacement searches.

Airtec DSWPM Selection Questions

Is DSWPM an ISO 6432 pneumatic cylinder?

Airtec's own technical catalogue does not describe the DSWPM 32–63 mm range as ISO 6432. It identifies it as a round-cylinder range, so Cylinder Warehouse does not present ISO 6432 as a confirmed DSWPM standard.

How long can an Airtec DSWPM stroke be?

Airtec documents customer-specific strokes from 1 to 1000 mm, subject to the mechanical limits of the piston rod and application. Numerous standard stroke lengths are also listed.

Is DSWPM magnetic?

Yes. Magnetic piston construction is standard on DSWPM, allowing suitable Airtec cylinder switches to be used for position sensing.

Does DSWPM have adjustable cushioning?

Standard DSWPM does not use the V designation for adjustable cushioning. Airtec identifies V as the code for adjustable end-position cushioning within the wider DSWP family, so a cushioned variant should be selected from the appropriate complete MPN.

Is the DSWPM piston rod stainless steel?

No. Airtec specifies a hard chrome-plated steel piston rod. The cylinder tube is 1.4301 stainless steel.
