This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE20X5 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE20X5 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 ATP20X5
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP20X5 is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø20mm 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 ATE20X5 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP20X5
A single acting pull cylinder with spring return (discontinued), the ATP20X5 uses an internal spring to hold the 10 mm rod extended and applies compressed air to retract it. The 20 mm bore delivers 88.1 N of pull at 0.5 MPa and 135.2 N at 0.7 MPa, both figures already net of the spring, and it needs at least 0.2 MPa to overcome the spring. Its hard-anodized aluminium body with an S45C hard-chrome rod is an ISO 21287 class short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped fixtures and guarding.
For sizing, treat roughly 53 N (about 60% of the 0.5 MPa rating) as the working pull for real tasks, which corresponds to lifting around 4 kg vertically with a 2:1 margin. The fixed TPU bumper at each end only decelerates the rod at the ends of travel and never locks a load in place; on air loss the spring simply returns the rod to its extended home. This model is discontinued, and the current-production drop-in is the ATE20X5 - confirm the ISO 21287 mounting dimensions before swapping, since the ATP follows a DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE20X5 (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 (Ø20mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 88.1 N |
| 0.7 MPa | 135.2 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 ATP20X5 Is Used
Fixture gate release
The 88.1 N spring-extended rod holds a small drill-press jig gate closed; a 0.5 MPa air signal retracts it 5 mm so the operator can unload a machined aluminium bracket.
Label head lift-off
On a bottling line, the spring keeps a hot-stamp head pressed onto a vial label; air pulls the head back 5 mm between bottles at up to 500 mm/s.
Fail-safe probe retraction
A spring-extended depth probe rests against a cast housing; losing air pressure returns it to extended home position, so the line cannot run with the probe retracted.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP20X5 with the ATE20X5
If 88.1 N at 0.5 MPa is marginal for your pull task, step up to the 25 mm bore (170.9 N at 0.5 MPa); if the load is lighter and space tighter, the 16 mm bore gives 53.3 N. The 5 mm stroke sits well inside the 100 mm maximum standard stroke for bore 20, so no made-to-order stroke is needed. This unit has the female M6x1.0 rod thread and PT ports; no magnet is fitted, so if you later need CMSE or DMSE switches, order the -S variant. Plan the swap to the ATE20X5, the current ISO 21287 successor in the same force class.
Replacement checklist
- ✓ Current-production ACE → ATE20X5
- ✓ 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 ATP20X5 FAQ
It is a single acting pull cylinder: the spring extends the rod and air retracts it. Pull is 88.1 N at 0.5 MPa and 135.2 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, air filtered to 40 um, speed 50-500 mm/s, and temperature -20 to +70 C. The 20 mm bore uses M5x0.8 ports and a female M6x1.0 rod thread.
No - the ATP family is discontinued. The current-production replacement is the ATE20X5 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class. Because the ATP follows a DIN-standard body, confirm the ISO 21287 mounting dimensions before ordering the swap. Note this unit has no magnet; the optional -S code is what enables CMSE / DMSE switches.
