This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X125S, 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 ACP63X125S
The AirTAC ACP Compact Cylinder ACP63X125S 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 ACE63X125S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X125S
The ACP63X125S is a double acting compact cylinder in the DIN-standard ACP series, with a 63 mm bore, 125 mm stroke and a 16 mm hard-chrome S45C rod on a hard-anodized aluminium body. 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 short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and guarding where a full-length body cannot. This S-coded unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing.
AirTAC has discontinued the ACP family; the current-production successor is ACE63X125, which swaps the P for an E and matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN standard. Fixed TPU bumpers sit at both ends, speed runs 30-500 mm/s, and the 1/8" port is set by the bore.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X125S (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 (Ø63mm)
| 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 ACE63X125S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP63X125S Is Used
Bottling line pusher
With 1558.6 N push at 0.5 MPa, the 63 mm bore ejects full shrink-wrapped trays off a conveyor lane; the 125 mm stroke clears a standard tray width and the -S magnet feeds a CMSE switch to confirm retract.
Pallet stamping press
The 2182.1 N push at 0.7 MPa is enough to drive a date-code stamp into carton lids on a warehouse pallet line, with the fixed TPU bumper decelerating the rod at both ends of the 125 mm travel.
Machine guard clamp
On a CNC enclosure interlock, the compact short body fits inside the guard frame where an ISO 15552 profile cylinder would not, holding the latch with about 1458.1 N of pull force at 0.5 MPa.
Replacing the Airtac ACP Compact Cylinder ACP63X125S with the ACE63X125S
At 63 mm bore this model delivers 1558.6 N push at 0.5 MPa; step down to the 50 mm bore (981.7 N) for lighter clamping or up to the 80 mm bore (2513.3 N) for heavier press work. The 125 mm stroke sits well inside the 250 mm maximum standard stroke for this bore, so it is a catalogue length, not a made-to-order one. Remember that a plain cylinder 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 bolt to the same face, and the -S magnet on this unit enables CMSE / DMSE switches. Order ACE63X125 instead: ACP is discontinued and the ACE is the direct ISO 21287 replacement.
Replacement checklist
- ✓ Current-production ACE → ACE63X125S
- ✓ 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 ACP63X125S FAQ
At 0.5 MPa the 63 mm bore 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 pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed 30-500 mm/s.
Order ACE63X125, the ISO 21287 successor: swap the P for an E and you get the same 63 mm bore, 125 mm stroke and force class in a current-production compact body. Check the ISO 21287 mounting dimensions against your fixture before swapping, because the ACP followed a DIN standard. This S-coded unit already carries the optional -S magnet for CMSE / DMSE switches; on the ACE you specify the magnet variant the same way. The female M10x1.5 rod thread and 1/8" port carry over by bore size.
