This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE50X80, the same code under the new prefix. 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 ACP Compact Cylinder ACP50X80
The AirTAC ACP Compact Cylinder ACP50X80 is a double acting DIN-standard tight/compact air cylinder with a Ø50mm bore and 80mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE50X80 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP50X80
A double acting compact cylinder built to the DIN-standard short-body format, the ACP50X80 pairs a 50 mm bore with an 80 mm stroke and delivers 981.7 N of push force and 881.2 N of pull force at 0.5 MPa, rising to 1374.4 N on extension at 0.7 MPa. Its hard-anodized aluminium body with an S45C hard-chrome rod runs on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, with a fixed TPU bumper at each end. This model is discontinued; the current-production successor is ACE50X80.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight welding jigs and packaging guards where a full-length body cannot. FA/FB flange, LB foot and CA/CB clevis brackets bolt straight to the face, and the optional -S magnet enables CMSE / DMSE switches; without -S there is no magnet.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE50X80 (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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 kgf | |
The ACE50X80 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
Where the Airtac ACP Compact Cylinder ACP50X80 Is Used
CNC fixture clamping
The 981.7 N push force clamps steel housings in machining fixtures, and the short body fits inside the fixture footprint where a full-length profile cylinder would overhang.
Carton press-down station
An 80 mm stroke presses flaps or inserts on a packaging line at up to 500 mm/s, with the fixed TPU bumper softening end-of-travel contact.
Pallet gate actuator
Swinging or lifting pallet-line gates with about 50 kg of vertical load equivalent, using the CA/CB clevis mount for the pivot action.
Replacing the Airtac ACP Compact Cylinder ACP50X80 with the ACE50X80
At 80 mm stroke this sits mid-range for the 50 mm bore, whose maximum standard stroke is 250 mm. If 981.7 N at 0.5 MPa is more than the job needs, the 40 mm bore gives 628.3 N push; if the load is heavier, step up to the 63 mm bore for 1558.6 N. Remember the piston drifts when air is lost, so add a rod lock or pilot check valve for held loads. Order the -S code if CMSE / DMSE position sensing is required, and confirm ISO 21287 mounting dimensions before swapping to the ACE50X80 replacement.
Replacement checklist
- ✓ Current-production ACE → ACE50X80
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACP Compact Cylinder ACP50X80 FAQ
At 0.5 MPa it pushes 981.7 N and pulls 881.2 N; at 0.7 MPa those rise to 1374.4 N and 1233.7 N. The theoretical maximum is 200.2 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the rod is 16 mm with an M10x1.5 female thread on a 1/8" port.
No - the ACP family is discontinued. The current-production direct is ACE50X80, the ISO 21287 version with the same 50 mm bore, 80 mm stroke and force class. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to the DIN-standard format.
