This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE40X80B, 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.

The AirTAC ACP Compact Cylinder ACP40X80B is a double acting DIN-standard tight/compact air cylinder with a Ø40mm bore and 80mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE40X80B (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP40X80B is a double acting compact cylinder with a 40 mm bore and 80 mm stroke, built to the DIN-standard short-body format with a hard-anodized aluminium body and an S45C hard-chrome piston rod. At 0.5 MPa it pushes 628.3 N and pulls 571.8 N, rising to 879.6 N on the extend stroke at 0.7 MPa, with a theoretical ceiling of 128.1 kgf at 1.0 MPa. The male rod thread from the B code bolts straight to standard I/Y knuckles. Air supply is 0.15-1.0 MPa (22-145 psi), speed range 30-500 mm/s, and each end carries a fixed TPU bumper.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guarding and slide assemblies. No magnet is fitted on this code; order the optional -S version if you need CMSE or DMSE switch sensing. This model is discontinued - the current-production direct is the ACE40X80, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE40X80B (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.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 572 N |
| 0.7 MPa | 880 N | 800 N |
| Max (@1.0 MPa) | 128 kgf | |
The ACE40X80B produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| ACP | DIN compact cylinder (double-acting, discontinued). |
|---|---|
| 40 | Bore size in mm. |
| ×80 | Stroke length in mm. |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
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).
The 628.3 N push at 0.5 MPa secures aluminium housings in a machining fixture, and the short body fits inside the clamp pocket where a full-length profile cylinder cannot.
With about 32 kg of vertical lift capability and 30-500 mm/s speed, the 80 mm stroke kicks off-spec cartons from a conveyor lane without slowing the line.
At 0.7 MPa the 879.6 N extend force presses bearings into small pump housings on a manual assembly bench, with the male rod thread taking a standard knuckle.
Pick the 40 mm bore when your jig needs more than a 32 mm bore (402.1 N push at 0.5 MPa) can deliver but a 50 mm bore (981.7 N) would be oversized for the fixture. The 80 mm stroke sits well inside the 200 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order build. Remember that a plain cylinder of this type drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. FA/FB flange, LB foot and CA/CB clevis mounts suit the face, and the optional -S magnet enables CMSE / DMSE switches. Since ACP is discontinued, order the ACE40X80 and verify the ISO 21287 mounting dimensions.
Replacement checklist
At 0.5 MPa it pushes 628.3 N and pulls 571.8 N; at 0.7 MPa push is 879.6 N and pull 800.5 N. The theoretical maximum is 128.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s. The 12 mm rod ends in a male thread (B code) and the air port is 1/8" PT.
No - the ACP family is discontinued. The current-production replacement is the ACE40X80, an ISO 21287 compact cylinder in the same 40 mm bore, 80 mm stroke and force class. It is a direct successor, but because the ACP was built to a DIN standard you should confirm the ISO 21287 mounting dimensions before swapping. If you need position sensing, order the ACE with the optional -S magnet for CMSE / DMSE switches.
