This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X120, 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 ACP63X120
The AirTAC ACP Compact Cylinder ACP63X120 is a double acting DIN-standard tight/compact air cylinder with a Ø63mm bore and 120mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE63X120 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X120
The ACP63X120 is a double acting compact cylinder in the DIN-standard ACP series, with a 63 mm bore and 120 mm stroke on a 16 mm hard-chrome S45C rod. Air drives the piston both ways, and fixed TPU bumpers sit at each end of the 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 317.9 kgf at 1.0 MPa.
Because the short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight machine frames and gantries. Note this model is discontinued: the current-production direct is ACE63X120, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X120 (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 ACE63X120 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 ACP63X120 Is Used
Press-fit station on an assembly line
With 1558.6 N push at 0.5 MPa, the 63 mm bore presses bearings or bushings into housings, and the short body fits inside the press frame where a full-length profile cylinder cannot.
Stopper gate on a pallet conveyor
The 120 mm stroke raises and lowers a stopper blade between pallets, and the fixed TPU bumpers soften the end-of-travel approach at speeds up to 500 mm/s.
Clamp fixture for machined castings
Pulling 1458.1 N at 0.5 MPa, the cylinder clamps a casting in a machining fixture via a CA clevis, with LB foot mounting keeping the jig footprint small.
Replacing the Airtac ACP Compact Cylinder ACP63X120 with the ACE63X120
At 63 mm bore this sits in the mid-heavy force band: 1558.6 N push at 0.5 MPa. If your load needs under 981.7 N, the ACP50 saves air and cost; if you need beyond 2513.3 N, step up to the ACP80. Both neighbours share the same 1/8" port and mounting family. The 120 mm stroke is well inside the 250 mm standard limit for this bore. FA/FB flange, LB foot and CA/CB clevis brackets bolt straight on, and the optional -S magnet code enables CMSE / DMSE switches - without -S there is no magnet. Remember a plain cylinder drifts when air is lost, so add a rod lock or pilot check valve for held loads. Order ACE63X120 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE63X120
- ✓ 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 ACP63X120 FAQ
Push is 1558.6 N and pull 1458.1 N at 0.5 MPa; at 0.7 MPa push is 2182.1 N and pull 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. It is double acting with a 63 mm bore, 120 mm stroke, 16 mm rod, 1/8" port, female M10x1.5 rod thread, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s and temperature -20 to +70 C on air filtered to 40 um.
AirTAC no longer produces the ACP family. The current-production successor is ACE63X120, an ISO 21287 compact cylinder in the same bore, stroke and force class. The ACE is a direct swap, but because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions against your fixture before ordering. If you also need position sensing, order the ACE with the magnet option for CMSE / DMSE switches.
