This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X45S, 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 ACP63X45S
The AirTAC ACP Compact Cylinder ACP63X45S is a double acting DIN-standard tight/compact air cylinder with a Ø63mm bore and 45mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE63X45S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X45S
The ACP63X45S is a double acting DIN-standard compact cylinder with a 63 mm bore and 45 mm stroke, delivering 1558.6 N on the push stroke and 1458.1 N on the pull stroke at 0.5 MPa. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits so well into tight welding jigs and press fixtures. The hard-anodized aluminium body carries threaded aluminium covers, an S45C hard-chrome rod with a female M10x1.5 thread, and a fixed TPU bumper at each end.
Because the S code is in this model, the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the body for end-of-stroke signalling. Note that this model is discontinued: the current-production replacement is ACE63X45, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X45S (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 ACE63X45S 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 ACP63X45S Is Used
Clamping fixture on a CNC machining line
The 1558.6 N push force at 0.5 MPa clamps steel housings securely in a milling fixture, and the 45 mm stroke keeps the jig footprint small inside the machine envelope.
Short-stamp marking press
With 2182.1 N available at 0.7 MPa, this bore drives date-code stamps and light embossing dies where a full-length profile cylinder would not fit under the press frame.
Packaging line divert gate
The fitted -S magnet feeds CMSE or DMSE switch signals to the PLC for gate-position confirmation, while the short body mounts between conveyor frames with an FB flange.
Replacing the Airtac ACP Compact Cylinder ACP63X45S with the ACE63X45S
At 63 mm bore this sits in the mid-heavy force band: 1558.6 N push at 0.5 MPa, rising to 2182.1 N at 0.7 MPa, with a theoretical 317.9 kgf at 1.0 MPa. If your load needs less than about 981.7 N at 0.5 MPa, the 50 mm bore covers it; if you need more than 2182.1 N, step up to the 80 mm bore at 2513.3 N. The 45 mm stroke is well inside the 250 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, so add a rod lock or pilot check valve if the load must stay put. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the same face. This ACP version is discontinued; order ACE63X45 as the direct successor and verify the ISO 21287 hole pattern first.
Replacement checklist
- ✓ Current-production ACE → ACE63X45S
- ✓ 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 ACP63X45S FAQ
At 0.5 MPa the push stroke delivers 1558.6 N and the pull stroke 1458.1 N. At 0.7 MPa those rise to 2182.1 N push and 2041.3 N pull, and the 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, speed range 30-500 mm/s, and a 16 mm hard-chrome rod on an M10x1.5 female thread. A practical rule of thumb is to size the task at about 935 N of push, roughly 60% of the 0.5 MPa rating.
Yes, this model is no longer in production. The current direct is ACE63X45, the ISO 21287 successor in the same bore, stroke and force class - just swap the P for an E. Because the ACP was built to the DIN standard, confirm the ISO 21287 mounting dimensions before swapping. The -S magnet option that this model carries carries over in the ACE family, so CMSE and DMSE switches remain available, and FA/FB flange, LB foot and CA/CB clevis mountings are supported.
