This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X50S, 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 ACP63X50S
The AirTAC ACP Compact Cylinder ACP63X50S is a double acting DIN-standard tight/compact air cylinder with a Ø63mm bore and 50mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE63X50S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X50S
A double acting compact cylinder in the DIN-standard ACP series, the ACP63X50S pairs a 63 mm bore with a 50 mm stroke and carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be fitted for end-of-stroke signalling. At 0.5 MPa it pushes with 1558.6 N and pulls with 1458.1 N, rising to 2182.1 N push at 0.7 MPa. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight machine frames and fixture plates.
This model is discontinued; the current-production direct is ACE63X50, same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping. Air supply must be filtered to 40 um, 0.15-1.0 MPa (22-145 psi), speed range 30-500 mm/s, fixed TPU bumpers at both ends.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X50S (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 ACE63X50S 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 ACP63X50S Is Used
CNC fixture clamping
The 1558.6 N push at 0.5 MPa clamps aluminium housings in a machining fixture, and the 50 mm stroke clears the loader arm quickly.
Packaging line pushers
Mounted under a carton conveyor, the compact body ejects boxes between guard rails where a full-length profile cylinder would not fit.
Assembly press assist
At 0.7 MPa the 2182.1 N force presses bearings into small motor end bells on a semi-automatic assembly bench.
Replacing the Airtac ACP Compact Cylinder ACP63X50S with the ACE63X50S
For a 50 mm stroke in this force band, bore 63 delivers 1558.6 N push at 0.5 MPa; step down to bore 50 (981.7 N) for lighter clamping or up to bore 80 (2513.3 N) for heavier press-fit work. Note 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 plus the fitted -S magnet for CMSE/DMSE switches make fixture integration straightforward. Order ACE63X50 as the current replacement and verify ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE63X50S
- ✓ 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 ACP63X50S FAQ
Push is 1558.6 N and pull is 1458.1 N at 0.5 MPa; at 0.7 MPa push rises to 2182.1 N and pull to 2041.3 N. Theoretical maximum is 317.9 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s, temperature -20 to +70 C. The rod is 16 mm with an M10x1.5 female thread and the air port is 1/8" (PT).
Order ACE63X50, the current ISO 21287 successor: swap the P for an E and you get the same 63 mm bore, 50 mm stroke and force class in a short-body compact cylinder. Before swapping, confirm the ISO 21287 mounting dimensions against your existing fixture, since the ACP was built to the older DIN standard. This model carries the -S magnet for CMSE/DMSE switches; on the ACE check the equivalent sensor option when ordering.
