This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE25X5S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE25X5S in place of this model. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.
Airtac ATP Single Acting Port Compact Cylinder ATP25X5S
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP25X5S is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø25mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE25X5S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP25X5S
The ATP25X5S is a single acting pull cylinder with spring extend: the built-in spring holds the rod out and compressed air retracts it, so at rest the piston sits extended and it fails to the extended position on air loss. This 25 mm bore size delivers 170.9 N of pull at 0.5 MPa (253.3 N at 0.7 MPa), net of the return spring, over a short 5 mm stroke with an M5x0.8 port. Note that this ATP family is discontinued; the current-production successor is the ATE25X5, and buyers should confirm ISO 21287 mounting dimensions before swapping.
The short-body build saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight fixtures and guarding. The S code on this model means the optional magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped on for end-of-stroke detection. For sizing, treat roughly 103 N (0.6 of the 0.5 MPa pull) as the usable working force, which is about 8 kg of vertical load with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE25X5S (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø25mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 170.9 N |
| 0.7 MPa | 253.3 N |
Single-acting pull: the spring extends the rod; air retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

Where the Airtac ATP Single Acting Port Compact Cylinder ATP25X5S Is Used
Spring-out clamp on a small drilling jig
The spring keeps the clamp arm engaged on an aluminium bracket; 170.9 N of pull at 0.5 MPa holds the part while a 5 mm air pulse releases it between cycles.
Position-confirm ejector in an electronics assembly head
With the fitted magnet and a DMSE switch, the controller verifies the 5 mm retract of a pin ejector before the pick-and-place head indexes to the next PCB.
Normally-extended gate pin on a packaging line
The rod stays out to block cartons at a lane diverter; losing air pressure fails the pin to extended, and a short air stroke retracts it for one-box release.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP25X5S with the ATE25X5S
Compare against neighbours: the 20 mm bore pulls 88.1 N at 0.5 MPa while the 32 mm bore reaches 296.0 N, so pick the 25 mm when your clamp or eject needs fall between those. The 5 mm stroke suits micro-positioning and confirmation moves only; single acting pull strokes stay short, and speed runs 50-500 mm/s. Mounting brackets and the female M6x1.0 rod thread match the standard fixture family, and the ATE25X5 is the drop-in replacement to order going forward.
Replacement checklist
- ✓ Current-production ACE → ATE25X5S
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ATP Single Acting Port Compact Cylinder ATP25X5S FAQ
It is a single acting pull cylinder, spring extend: pull is 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa, both net of the return spring. Working pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof; at least 0.2 MPa is required to overcome the spring. Speed range is 50-500 mm/s, the port is M5x0.8, the rod thread is female M6x1.0, and air must be filtered to 40 um.
The short-body design saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it fits where a full-length cylinder cannot. This S-version carries the optional magnet, so CMSE or DMSE reed or solid-state switches mount directly on the body for end-of-stroke signalling. Since the ATP25X5S is discontinued, order the ATE25X5 replacement and confirm the ISO 21287 mounting dimensions first.
