This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X110-75, 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 ACPJ12X110-75
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X110-75 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 ACEJ12X110-75 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-75
The ACPJ12X110-75 is a double acting compact cylinder with an adjustable extend stroke: the -75 code gives a 75 mm stop-screw window, so the 110 mm stroke can be trimmed anywhere in a 35-110 mm range on site. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 / 59.4 N at 0.7 MPa, 11.5 kgf theoretical maximum at 1.0 MPa). Note that 110 mm is beyond the 50 mm maximum standard stroke for this bore, so this unit is a made-to-order build.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits slim slides and guarded stations. In practice, plan on about 34 N (roughly 60% of the push rating) for real work at 0.5 MPa, which lifts about 2.9 kg vertically with a 2:1 margin. This model carries no magnet because the -S code was not ordered; order ACPJ12X110-75S if CMSE / DMSE switches are needed later. The ACPJ family is discontinued, and the current-production replacement is ACEJ12X110 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X110-75 (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 ACPJ12X110-75 Is Used
Small-part ejection on assembly fixtures
A 35-110 mm adjustable stroke lets the stop screw be tuned per fixture variant when kicking clips or pins off a jig, with 56.5 N of push at 0.5 MPa enough for light parts.
Position-checked test stations
Order the -S version with CMSE / DMSE switches to confirm end positions on a compact leak or label-check station where a full-length cylinder will not fit.
Light clamping in slim enclosures
About 34 N of usable force at 0.5 MPa clamps small brackets or PCBs inside narrow machine frames, with the fixed TPU bumper softening both stroke ends.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-75 with the ACEJ12X110-75
Bore 12 mm is the smallest in the range, so if 56.5 N of push at 0.5 MPa is marginal for the load, step up to bore 16 mm (100.5 N push / 75.4 N pull at 0.5 MPa) or bore 20 mm (157.1 N / 117.8 N). The stop screw only shortens the extend stroke and is not a mid-stroke lock: on air loss the piston still drifts, so do not use it to hold a load. Mounting is FA/FB flange or LB foot on the standard face, and the optional -S magnet enables CMSE / DMSE switch position feedback. For new projects, specify the ACEJ12X110, the current drop-in successor.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X110-75
- ✓ 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 ACPJ12X110-75 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 -75 code is a 75 mm adjustment window: an external stop screw shortens the 110 mm extend stroke to any length from 35 mm to 110 mm. It cannot lengthen the stroke past 110 mm, and the stop is not a load-holding brake - on air loss the piston still drifts. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
No - the ACPJ family is discontinued. The current-production replacement is ACEJ12X110, made by swapping the P for an E; it matches the same 12 mm bore, 110 mm stroke and force class with a short ISO 21287 body, fixed TPU bumpers at both ends, FA/FB flange or LB foot mounting and an optional -S magnet for CMSE / DMSE switches. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. The 110 mm stroke is a made-to-order length for this bore, so lead time should be confirmed.
