This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X120B, 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 ACP12X120B
The AirTAC ACP Compact Cylinder ACP12X120B 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 ACE12X120B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X120B
The ACP12X120B is a double acting DIN-standard compact cylinder with a 12 mm bore and a made-to-order 120 mm stroke, well beyond the 50 mm standard limit for this bore. It delivers 56.5 N push and 42.4 N pull at 0.5 MPa, rising to 79.2 N push at 0.7 MPa, with a theoretical peak of 11.5 kgf at 1.0 MPa. The B code gives a male rod thread on the 6 mm rod, and the port is M5x0.8. Note that this model is discontinued; the current-production successor is the ACE12X120 (swap the P for an E) in the same bore, stroke and force class.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures, small gantries and guarded cells. A fixed TPU bumper at each end decelerates the piston, and the hard-anodized aluminium body carries an S45C hard-chrome rod. The optional -S magnet enables CMSE / DMSE switches; without it no sensing is possible. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X120B (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 ACE12X120B 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 ACP12X120B Is Used
Lab sample pusher
Ejects microscope slide trays or vial racks from a compact analyzer deck, where the 56.5 N push at 0.5 MPa is ample and the 120 mm stroke crosses a narrow conveyor gap.
Micro-assembly eject pin
Kicks small connectors off a pick-and-place nest in electronics assembly; the short body fits between fixture plates where a full-length profile cylinder cannot.
Carton flap kicker
Taps folding-carton flaps into place on a small packaging line, using the male rod thread with an I knuckle for a light swing linkage.
Replacing the Airtac ACP Compact Cylinder ACP12X120B with the ACE12X120B
At 56.5 N push (0.5 MPa) this 12 mm bore suits light clamping and small part ejection; step up to the 16 mm bore (100.5 N push) if the load grows, or down to nothing smaller since 12 mm is the smallest in the family. The 120 mm stroke is non-standard for this bore (max standard 50 mm), so it is built to order. A plain cylinder drifts when air is lost, so add a rod lock or pilot check valve for held loads. If you need position feedback, order the -S magnet version for CMSE / DMSE switches. For new projects, specify the ACE12X120 instead and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACE12X120B
- ✓ 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 ACP12X120B FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.2 N and pulls 59.4 N; theoretical maximum is 11.5 kgf at 1.0 MPa. The 120 mm stroke exceeds the 50 mm standard maximum for the 12 mm bore, so it is a made-to-order stroke. Speed range is 30-500 mm/s and operating pressure is 0.15-1.0 MPa (22-145 psi).
Sensing requires the optional -S magnet code; this version has no magnet, so CMSE or DMSE switches cannot be mounted unless you order the -S variant. The ACP12X120B itself is discontinued. The current direct is the ACE12X120 (ISO 21287), which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
