This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X110-30S, 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 ACPJ Adjustable Compact Cylinder ACPJ12X110-30S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X110-30S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 110mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X110-30S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-30S
This ACPJ12X110-30S is a double acting, adjustable-stroke compact cylinder with a 12 mm bore and a made-to-order 110 mm stroke. Air drives the rod out and pulls it back, and the -30 code gives a 30 mm stop-screw window, so the extend stroke can be trimmed anywhere between 80 and 110 mm on site. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those figures rise to 79.2 N and 59.4 N, with a theoretical peak of 11.5 kgf at 1.0 MPa. A practical rule of thumb: plan on roughly 34 N of real work (about 0.6 of the push rating), which lifts around 3 kg vertically with margin to spare.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures where a full-length body will not reach. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and the fitted -S magnet accepts CMSE / DMSE reed or solid-state switches. Note this model is discontinued: the current-production drop-in is the ACEJ12X110, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X110-30S (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 kgf |
ACPJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-30S Is Used
Small-part ejection in assembly fixtures
The 56.5 N push at 0.5 MPa is enough to kick finished micro-components off a nest into a chute, with the 80-110 mm adjustable range tuned per fixture.
Position-flagged slide in a test station
With the fitted -S magnet, CMSE or DMSE switches report extend and retract on a 110 mm stroke, ideal for go/no-go checks on connector or PCB assemblies.
Light hold-down on packaging lines
About 34 N of usable force (roughly 3 kg vertical equivalent) holds blister packs or pouches steady during a sealing or coding step in tight spaces.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-30S with the ACEJ12X110-30S
At 56.5 N push (0.5 MPa) this 12 mm bore suits light clamping, ejecting and sorting of small parts; if your load needs more, step up to the 16 mm bore at 100.5 N or the 20 mm bore at 157.1 N in the same compact family. If 56.5 N is generous, there is no smaller ACPJ bore, so consider a shorter stroke or a lower pressure setting instead. The stop screw trims the extend stroke only within the 30 mm window - it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. Mounting is FA/FB flange or LB foot with PT ports (M5x0.8 on this bore), and the female M3x0.5 rod thread takes standard I/Y knuckles. Because the ACPJ is discontinued, order the ACEJ12X110 as the current replacement and verify the ISO 21287 footprint first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X110-30S
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-30S FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa push rises to 79.2 N and pull to 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The 12 mm bore uses an M5x0.8 port and a 6 mm rod with female M3x0.5 thread. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, and the 110 mm stroke is a made-to-order length above the 50 mm standard maximum for this bore, trimmed by up to 30 mm via the stop screw.
The short ISO 21287-class aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits slim jigs and guards. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped on for end-of-stroke signalling. Fixed TPU bumpers decelerate the piston at both ends, and mounting is via FA/FB flange or LB foot. Since the ACPJ is discontinued, plan your swap to the ACEJ12X110 and confirm the ISO 21287 mounting dimensions before ordering.
