This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X110-50, 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 ACPJ12X110-50
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X110-50 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 ACEJ12X110-50 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-50
Double acting and adjustable, the ACPJ12X110-50 is a discontinued DIN-standard compact cylinder with a 12 mm bore and a made-to-order 110 mm stroke (above the 50 mm standard maximum for this bore). A stop screw trims the extend stroke anywhere in the ordered 50 mm window, so the working range is 60-110 mm. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; a practical rule of thumb is to plan for roughly 34 N (about 3 kg of vertical lift) of real work, leaving margin on the rating.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits cramped jigs and guarding. Air ports are M5x0.8, the rod end is female M3x0.5, and a fixed TPU bumper sits at both ends. Since this model is discontinued, order the current ACEJ12X110 instead and confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X110-50 (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 ACPJ12X110-50 Is Used
Ejector on a small assembly press
The 60-110 mm trimming range lets a fixture builder dial the push-off stroke per part, using about 34 N of usable force at 0.5 MPa for light plastic housings.
Slide clamp inside a compact jig
A body roughly half the length of an ISO 15552 profile cylinder fits where full-size bores cannot, clamping PCB fixtures or small castings on an automation cell.
Position-flag actuator on a test bench
With the -S magnet variant and CMSE / DMSE switches, the trimmed stroke can signal end-of-travel on a leak-test or marking station; this non-S version carries no magnet.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-50 with the ACEJ12X110-50
Size both ways: the 16 mm bore gives 100.5 N push at 0.5 MPa if 56.5 N feels tight, while a smaller 12 mm fixed-stroke ACP works when no trimming is needed. Note that the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. Mounting options are FA/FB flange or LB foot; add the -S code if you later need CMSE / DMSE switches, because this version has no magnet. For new builds, specify the ACEJ12X110.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X110-50
- ✓ 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 ACPJ12X110-50 FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa, 79.2 N push and 59.4 N pull; theoretical maximum is 11.5 kgf at 1.0 MPa. The -50 code gives a 50 mm adjustment window, so the 110 mm extend stroke can be set anywhere from 60 to 110 mm. The 110 mm stroke is made to order, since the standard maximum for a 12 mm bore is 50 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
No - the ACPJ12X110-50 is discontinued. The current-production replacement is the ACEJ12X110, an ISO 21287 compact cylinder in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, because the ACP follows the older DIN-standard footprint. FA/FB flange and LB foot mounts, plus the optional -S magnet for CMSE / DMSE switches, are selected in the ACE ordering code.
