This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE80X120, 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 ACP80X120
The AirTAC ACP Compact Cylinder ACP80X120 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 ACE80X120 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP80X120
A double acting compact cylinder in the discontinued AirTAC ACP series, the ACP80X120 pairs an 80 mm bore with a 120 mm stroke and a 20 mm hard-chrome S45C rod on a hard-anodized aluminium body. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N on the extend stroke 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 was a favourite inside press frames, weld fixtures and guarded gantry axes.
Fixed TPU bumpers decelerate the piston at both ends, speed runs 30-500 mm/s, and the rod ends in a female M12x1.75 thread with 1/4" ports. This model is discontinued: the current-production direct is ACE80X120, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE80X120 (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 ACE80X120 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 ACP80X120 Is Used
Clamp fixture on a machining centre
The 2513.3 N push at 0.5 MPa holds steel housings against a milling fixture, and the short body tucks inside the fixture base where a full-length profile cylinder would not fit.
Press-fit station for bearing assembly
With about 154 kgf of practical push at 0.5 MPa, the 120 mm stroke seats bearings into housings on an automotive sub-assembly line at 30-500 mm/s.
Replacing the Airtac ACP Compact Cylinder ACP80X120 with the ACE80X120
At this force class the 80 mm bore sits between the 63 mm (1558.6 N push at 0.5 MPa) and the 100 mm (3927.0 N push at 0.5 MPa); step down if 120 mm of stroke carries a lighter clamp load, or up to the 100 mm bore when you need headroom. The 120 mm stroke is well inside the 300 mm standard maximum for bore 80, so it is a catalogue item, not a made-to-order build. Remember that a plain ACP drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. Order the -S code if you want the optional magnet for CMSE / DMSE switches; without it no magnet is fitted. For new projects, specify ACE80X120 instead and verify the ISO 21287 mounting footprint.
Replacement checklist
- ✓ Current-production ACE → ACE80X120
- ✓ 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 ACP80X120 FAQ
Push 2513.3 N and pull 2356.2 N at 0.5 MPa; push 3518.6 N and pull 3298.7 N at 0.7 MPa; theoretical maximum 512.6 kgf at 1.0 MPa. It is a double acting compact cylinder, 80 mm bore, 120 mm stroke, 20 mm rod, 1/4" ports, female M12x1.75 rod thread, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, fixed TPU bumpers at both ends. The model is discontinued; ACE80X120 is the current replacement.
It uses a hard-anodized aluminium body with threaded aluminium covers, an S45C hard-chrome piston rod and fixed TPU bumpers that only decelerate the piston at each end - they never hold or brake a load. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder and accepts FA/FB flange, LB foot or CA/CB clevis mounting. Position sensing requires the optional -S magnet code, which enables CMSE / DMSE switches; without -S there is no magnet in the piston. Since this model is discontinued, order ACE80X120 and confirm the ISO 21287 mounting dimensions.
