This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE80X120S, 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 ACP80X120S
The AirTAC ACP Compact Cylinder ACP80X120S is a double acting DIN-standard tight/compact air cylinder with a Ø80mm bore and 120mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE80X120S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP80X120S
The ACP80X120S is a double acting compact cylinder with an 80 mm bore and 120 mm stroke, built to the DIN-standard short-body format with a hard-anodized aluminium body and an S45C hard-chrome piston rod. At 0.5 MPa it pushes with 2513.3 N and pulls with 2356.2 N, rising to 3518.6 N on the push stroke at 0.7 MPa, with a theoretical peak of 512.6 kgf at 1.0 MPa. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits so well inside welding gantries and press fixtures. Air supply runs 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and rod speed spans 30-500 mm/s.
The S in the model code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped straight onto the body for end-of-stroke signalling. Fixed TPU bumpers sit at both ends to soften the stroke terminations, but they do not hold anything in place: if air is lost the piston drifts, so add a rod lock or pilot check valve for a held load. This model is discontinued - the current-production direct is ACE80X120, the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping. For real-world sizing, treat roughly 1508 N (about 154 kg) as the usable push effort at 0.5 MPa rather than the full rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE80X120S (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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2356 N |
| 0.7 MPa | 3519 N | 3299 N |
| Max (@1.0 MPa) | 513 kgf | |
The ACE80X120S 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 ACP80X120S Is Used
Clamping in machining fixtures
With about 1508 N of usable push at 0.5 MPa, the 80 mm bore clamps aluminium housings or steel brackets firmly in CNC milling and drilling fixtures, and the short body fits inside the fixture base.
Ejector on packaging machinery
The 120 mm stroke and 30-500 mm/s speed range suit pushing filled cartons off a conveyor lane, and the fitted -S magnet lets a DMSE switch confirm end-of-stroke before the next cycle starts.
Replacing the Airtac ACP Compact Cylinder ACP80X120S with the ACE80X120S
At 80 mm bore this sits near the top of the compact range: 2513.3 N push at 0.5 MPa against 1558.6 N for a 63 mm bore, while the 100 mm bore reaches 3927.0 N if you need more. Keep the 120 mm stroke inside the 300 mm maximum standard stroke for this bore, so no made-to-order build is required. The female M12x1.25-class rod thread is actually M12x1.75 here, and the 1/4" port is fixed by the bore size. If you need position feedback, this S-coded unit already carries the -S magnet for CMSE / DMSE switches; FA/FB flange, LB foot and CA/CB clevis brackets bolt to the mounting face. Since ACP is discontinued, order ACE80X120 as the current equivalent and verify the ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACE80X120S
- ✓ 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 ACP80X120S FAQ
At 0.5 MPa the push force is 2513.3 N and the pull force is 2356.2 N; at 0.7 MPa push rises to 3518.6 N with 3298.7 N pull, and the theoretical maximum is 512.6 kgf at 1.0 MPa. The ACP family is discontinued, so the current-production replacement is ACE80X120 - same 80 mm bore, 120 mm stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP follows the DIN-standard format.
The compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guards and gantries. Because this model carries the optional -S magnet, CMSE or DMSE reed and solid-state switches mount directly on the body for position feedback. The rod ends in a female M12x1.75 thread, the port is 1/4", and FA/FB flange, LB foot or CA/CB clevis mounting can be specified.
