This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE80X20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE80X20S 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 ATP80X20S
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP80X20S is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø80mm bore and 20mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE80X20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP80X20S
A single acting pull cylinder with spring return, the ATP80X20S uses an 80 mm bore to deliver 2159.1 N of pull at 0.5 MPa (3101.6 N at 0.7 MPa), both figures already net of the return spring. The spring holds the rod extended at rest, so the assembly fails to the extended home position on air loss and needs at least 0.2 MPa of air to retract. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted directly on the body.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters when an 80 mm bore has to fit inside a press fixture or machine guard. In practice, plan on about 1295 N of usable pull at 0.5 MPa, which lifts roughly 110 kg vertically with a 2:1 margin. Note that this ATP series is discontinued; the current-production replacement is the ATE80X20, and you should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE80X20S (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 (Ø80mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 2159.1 N |
| 0.7 MPa | 3101.6 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 ATP80X20S Is Used
Clamp release in welding fixtures
Spring extension keeps clamps open during loading; 2159.1 N of air pull at 0.5 MPa retracts the plunger to lock a car-body panel before the weld gun fires.
Pallet gate lifting on conveyors
The spring raises a stop gate by 20 mm whenever air pressure drops, so a stalled line fails safe; about 110 kg vertical lift capacity covers heavy gate arms.
Slide retraction in CNC fixtures
Air retracts a locating slide inside a tight machining enclosure where the short body fits, and CMSE switches on the -S magnet confirm the retracted position to the PLC.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP80X20S with the ATE80X20S
At 0.5 MPa this bore pulls 2159.1 N net of the spring. If your load needs less, the 63 mm bore gives 1320.0 N; if you need more, the 100 mm bore reaches 3395.3 N. Remember the spring cannot hold a mid-stroke position - on air loss the rod goes to full extension. FA/FB flange, LB foot and CA/CB clevis mountings plus the fitted -S magnet for CMSE / DMSE switches make fixture integration straightforward. Order the ATE80X20 as the drop-in successor and verify mounting dimensions against the ISO 21287 datasheet.
Replacement checklist
- ✓ Current-production ACE → ATE80X20S
- ✓ 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 ATP80X20S FAQ
At 0.5 MPa the rod pulls 2159.1 N; at 0.7 MPa it pulls 3101.6 N. Both values are net of the return spring, so no derating is needed. The cylinder is single acting: the spring extends the rod and compressed air retracts it, with a minimum of 0.2 MPa required to overcome the spring. Operating range is 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa (215 psi), speed 50-500 mm/s, and the 1/4" port suits this 80 mm bore.
The ATP family is no longer in production. The current drop-in is the ATE80X20, which keeps the same 80 mm bore, 20 mm stroke and force class in an ISO 21287 compact body. Because the ATP was built to a DIN-standard compact format, confirm the ISO 21287 mounting dimensions before swapping. The fixed TPU bumpers at both ends carry over, and the -S magnet option for CMSE / DMSE switches remains available on the replacement.
