This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X80-30, 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 ACPJ12X80-30
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X80-30 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 80mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X80-30 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-30
The ACPJ12X80-30 is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 80 mm stroke by up to 30 mm, giving a usable range of 50-80 mm. This 12 mm bore unit is discontinued, and the current-production drop-in is the ACEJ12X80 in the same bore, stroke and force class. Its 80 mm stroke exceeds the 50 mm maximum standard stroke for bore 12, so it is a made-to-order build. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guards.
At 0.5 MPa the bore delivers 56.5 N push and 42.4 N pull; at 0.7 MPa that rises to 79.2 N push. Halving the 5.8 kgf vertical equivalent for a 2:1 margin, plan to lift about 2.9 kg vertically. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers at both ends, and runs 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). Note that no magnet is fitted on this version, so position switches cannot be mounted unless you order the optional -S magnet code.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X80-30 (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 ACPJ12X80-30 Is Used
Small-part press fit
Pressing dowel pins or bushings into plastic housings on an electronics assembly bench, where the 56.5 N push at 0.5 MPa is enough and the 50-80 mm trim range dials in the seating depth.
Gate and guard actuation
Swinging or sliding a small interlock gate on a packaging machine, with the short body fitting inside a guard where a full-length ISO 15552 profile cylinder would not.
Light pick-down station
Lowering a fixture clamp or light part weighing up to about 2.9 kg vertically in a test rig, using the stop screw to set a repeatable down position between 50 and 80 mm.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-30 with the ACEJ12X80-30
Size by force: bore 12 gives 56.5 N push at 0.5 MPa, while bore 16 reaches 100.5 N and bore 20 reaches 157.1 N under the same pressure - step up if your load needs more than about 34 N of real work. The 30 mm window only shortens the extend stroke; it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and CMSE / DMSE switches work only when the optional -S magnet is ordered. Since this model is discontinued, confirm ISO 21287 mounting dimensions and order the ACEJ12X80 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X80-30
- ✓ 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 ACPJ12X80-30 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, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: a stop screw shortens the 80 mm extend stroke, so the usable range is 50-80 mm. It runs on air at 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, with a 1.5 MPa (215 psi) proof pressure and a fixed TPU bumper at each end.
Only if you order the optional -S magnet version; this model code has no magnet, so CMSE or DMSE reed and solid-state switches cannot be mounted as-is. The ACPJ family is discontinued, and the current-production replacement is the ACEJ12X80 - swap the P for an E for the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN standard.
