This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X120, 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 ACP12X120
The AirTAC ACP Compact Cylinder ACP12X120 is a double acting DIN-standard tight/compact air cylinder with a Ø12mm bore and 120mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE12X120 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X120
Double acting on both strokes, the ACP12X120 is AirTAC's DIN-standard compact cylinder with a 12 mm bore and a 120 mm stroke. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N and 59.4 N at 0.7 MPa, with a theoretical peak of 11.5 kgf at 1.0 MPa. The 120 mm stroke is longer than the 50 mm standard limit for this bore, so it is a made-to-order build. Air is filtered to 40 um, pressure runs 0.15-1.0 MPa (22-145 psi), and speed spans 30-500 mm/s.
The hard-anodized aluminium body with an S45C hard-chrome rod saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which suits slim pick-and-place heads and tight machine frames. A fixed TPU bumper sits at both ends. This model is discontinued: the current direct is ACE12X120, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X120 (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 (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | 59 N |
| Max (@1.0 MPa) | 12 kgf | |
The ACE12X120 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 ACP12X120 Is Used
Small-part ejection from plastic molds
With 56.5 N push at 0.5 MPa, the 12 mm rod nudges finished micro-components off shallow mold nests on compact injection benches.
Lab sample pusher in diagnostic analyzers
The 120 mm reach slides reagent trays along a narrow deck, and the short body fits where a full-length cylinder cannot.
Position-flagged gate on electronics lines
Order the -S code so CMSE or DMSE switches report gate open and closed along the 120 mm travel.
Replacing the Airtac ACP Compact Cylinder ACP12X120 with the ACE12X120
At 56.5 N push, this 12 mm bore suits light clamping and small part transfer; step up to a 16 mm bore (100.5 N at 0.5 MPa) if loads grow, or down to the smallest size only for positioning tasks. Remember the piston drifts when air is lost, so add a rod lock or pilot check valve for held loads. The 120 mm stroke is non-standard for this bore and is built to order. The optional -S magnet enables CMSE / DMSE switches; FA/FB flange, LB foot and CA/CB clevis mountings bolt to the same face. Order ACE12X120 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE12X120
- ✓ 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 ACP12X120 FAQ
At 0.5 MPa the 12 mm bore delivers 56.5 N push and 42.4 N pull; at 0.7 MPa that is 79.2 N push and 59.4 N pull, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The 120 mm stroke exceeds the 50 mm standard maximum for this bore, so it is made to order. The model is discontinued and replaced by ACE12X120.
It is a compact double-acting cylinder with a hard-anodized aluminium body, an S45C hard-chrome rod on a 6 mm piston rod, an M3x0.5 female rod thread, an M5x0.8 PT port and a fixed TPU bumper at each end. Switches need the optional -S magnet code, which allows CMSE or DMSE sensors; without -S no magnet is fitted. FA/FB flange, LB foot and CA/CB clevis mountings are available.
