This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE25X20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE25X20 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 ATP25X20
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP25X20 is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø25mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE25X20 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP25X20
A single acting compact cylinder built to the DIN-standard short-body format, the ATP25X20 uses an internal spring to extend the rod and compressed air to retract it, so the assembly fails to the extended position whenever air is lost. With a 25 mm bore it delivers a net pull of 170.9 N at 0.5 MPa (253.3 N at 0.7 MPa, already subtracting the spring), needing just 0.2 MPa to overcome the spring. The hard-anodized aluminium body with an S45C hard-chrome rod keeps the envelope short - roughly 50% of the mounting length of an ISO 15552 profile cylinder - which is why it slots into tight jigs and guarding where a full-length body cannot.
Practical sizing: treat about 102 N (roughly 10 kg of force) as the usable working pull at 0.5 MPa, and expect it to lift about 8 kg vertically once a 2:1 margin is applied. The rod end carries a female M6x1.0 thread and the air port is M5x0.8. Note this model is discontinued: the current-production drop-in is the ISO 21287 ATE25X20 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since this unit follows the DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE25X20 (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 ATP25X20 Is Used
Spring-extend clamp on a small CNC fixture
The spring keeps a clamp pad engaged on an aluminium workpiece during milling; 170.9 N of air pull at 0.5 MPa retracts it for loading, and a lost-air fault leaves the part clamped.
Normally-out ejector in an electronics test nest
With the -S magnet ordered, a DMSE switch confirms the rod is home (spring-extended) before a PCB tray indexes; 20 mm of stroke is enough to clear the nest.
Return stroke on a compact pick check station
Air pull at 0.7 MPa (253.3 N net) draws a light gauge back into its pocket against seal drag, and the fixed TPU bumpers quiet the ends of the short 50%-of-15552 body.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP25X20 with the ATE25X20
At 170.9 N pull at 0.5 MPa, the 25 mm bore sits mid-range: step down to the 20 mm bore (88.1 N) for lighter spring-return clamping, or up to the 32 mm bore (296.0 N) when the return spring must also overcome seal drag on longer runs. Remember the spring only returns the rod to its extended home position - it will not hold a mid-stroke setting. Match FA/FB flange, LB foot or CA/CB clevis mounts to your fixture, and if you need position sensing, order the -S code, because without it no magnet is fitted and no CMSE or DMSE switch can be read. For new builds, specify the ATE25X20 instead, as this model is out of production.
Replacement checklist
- ✓ Current-production ACE → ATE25X20
- ✓ 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 ATP25X20 FAQ
It is a single acting pull cylinder: the spring extends the rod and air retracts it. Net of the spring, pull is 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa. Working pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, speed 50-500 mm/s, and the port is M5x0.8 with an M6x1.0 female rod thread.
Order the ATE25X20, the current-production ISO 21287 successor: swap the P for an E and you get the same 25 mm bore, 20 mm stroke and force class in a short-body format. Confirm the ISO 21287 mounting dimensions against your fixture first, since this unit follows the DIN-standard footprint, and remember the -S magnet option carries over if you run CMSE or DMSE switches.
