This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X125, 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 ACP63X125 is a double acting DIN-standard tight/compact air cylinder with a Ø63mm bore and 125mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE63X125 (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP63X125 is a double acting DIN-standard compact cylinder with a 63 mm bore and 125 mm stroke, driving a 16 mm hard-chrome S45C rod through a female M10x1.5 thread. Its hard-anodized aluminium body keeps the mounting length about 50% shorter than an ISO 15552 profile cylinder, so it slots into tight gantries and fixture plates. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those rise to 2182.1 N and 2041.3 N, with a theoretical peak of 317.9 kgf at 1.0 MPa.
The fixed TPU bumpers at both ends only soften end-of-travel; they never hold a load, so add a rod lock or pilot check valve where position must be kept on air loss. Note the magnet is not fitted on this code: order the optional -S version if you need CMSE or DMSE switches. This model is discontinued - the current-production direct is ACE63X125, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X125 (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 | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
The ACE63X125 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). |
|---|---|
| 63 | Bore size in mm. |
| ×125 | 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).
With 1558.6 N push at 0.5 MPa, the ACP63X125 clamps aluminium housings on a machining centre fixture, and the short body fits inside the fixture plate where a full-length cylinder cannot.
Mounted on an LB foot bracket, the 125 mm stroke diverts cartons between conveyor lanes at 30-500 mm/s, with the 1/8" port keeping plumbing compact.
For a 125 mm stroke in this force class, the 63 mm bore gives 1558.6 N push at 0.5 MPa; step down to a 50 mm bore (981.7 N) if the load is lighter, or up to an 80 mm bore (2513.3 N) for heavier clamping. Strokes up to 250 mm are standard for this bore, so 125 mm is a catalogue size. Choose FA/FB flange, LB foot or CA/CB clevis mounting to match the fixture, and add the -S code only if CMSE/DMSE position switches are needed. Since ACP is discontinued, order ACE63X125 as the current equivalent and verify the ISO 21287 mounting footprint first.
Replacement checklist
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa it pushes 2182.1 N and pulls 2041.3 N; the theoretical maximum is 317.9 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), speed 30-500 mm/s, and air filtered to 40 um. For real work, budget about 935 N (roughly 95 kg) at 0.5 MPa.
No - the ACP family is discontinued. The current-production replacement is ACE63X125, an ISO 21287 compact cylinder in the same bore, stroke and force class with matching FA/FB, LB and CA/CB mounting options. Because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. Also remember the magnet is only present when the optional -S code is ordered; without it, no CMSE or DMSE switch can be fitted.
