This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X75-10, 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 ACPJ12X75-10
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X75-10 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 75mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X75-10 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X75-10
The ACPJ12X75-10 is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 75 mm stroke by up to 10 mm, giving a usable 65-75 mm range on site. It is a DIN-standard short-body unit with a hard-anodized aluminium body, an S45C hard-chrome 6 mm rod and a fixed TPU bumper at each end. Note that the 75 mm stroke is longer than the 50 mm maximum standard stroke for bore 12, so this is a made-to-order build. The model is discontinued; the current-production replacement is ACEJ12X75.
At 0.5 MPa this 12 mm bore pushes 56.5 N and pulls 42.4 N (79.2 N push at 0.7 MPa, 11.5 kgf theoretical maximum). As a rule of thumb, plan on roughly 34 N of real work, which lifts about 3 kg vertically with margin. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. No magnet is fitted on this code; order the -S variant if you need CMSE / DMSE switch sensing.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X75-10 (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 ACPJ12X75-10 Is Used
Small-part ejection from fixtures
The 56.5 N push at 0.5 MPa and the 65-75 mm trimmed stroke suit knocking light aluminium or plastic parts off a CNC jig face after machining.
Lab sample press station
With about 34 N of usable force and a 6 mm hard-chrome rod, this cylinder presses test caps onto small vials in a benchtop assembly rig.
Carton flap tuck on a packing bench
The short body fits inside a tight packing-head frame, and the 10 mm adjustment window lets operators fine-tune the flap-tuck depth without shimming.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X75-10 with the ACEJ12X75-10
Size both ways: if 56.5 N of push at 0.5 MPa is marginal for your jig, step up to bore 16 (100.5 N push) or bore 20 (157.1 N); if the load is under about 34 N, this bore is the leanest choice. The adjuster is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, and on air loss the rod still drifts, so add a separate valve or lock for load holding. Mount with FA/FB flange or LB foot, and remember the magnet is the optional -S code. This model is discontinued - swap to ACEJ12X75 and confirm the ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X75-10
- ✓ 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 ACPJ12X75-10 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; the theoretical maximum is 11.5 kgf at 1.0 MPa. In practice plan on roughly 34 N of working force, which lifts about 3 kg vertically with a 2:1 margin. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the port is M5x0.8.
The -10 code gives a 10 mm window: a stop screw shortens the 75 mm extend stroke to any setting between 65 and 75 mm; it cannot lengthen the stroke past 75 mm. The TPU bumper at each end only decelerates the piston at the ends and never holds a load. The ACPJ family is discontinued - the current drop-in is ACEJ12X75, so confirm the ISO 21287 mounting dimensions before swapping.
