This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X35-10, 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 ACPJ12X35-10
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X35-10 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X35-10 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X35-10
A double acting compact cylinder with an adjustable extend stroke, the ACPJ12X35-10 runs a 12 mm bore over a 35 mm nominal stroke and delivers 56.5 N of push and 42.4 N of pull at 0.5 MPa (rising to 79.2 N at 0.7 MPa). The -10 code sets a 10 mm adjustment window: an external stop screw trims the extend stroke anywhere between 25 and 35 mm on site, so one cylinder covers several fixture positions. Its hard-anodized aluminium body is an ISO 21287 short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding where a full-length body cannot.
The fixed TPU bumper at each end decelerates the piston at the ends of travel only - it never locks or holds a load, and on air loss the piston still drifts, so do not treat the stop screw as a brake. Rod end is a female M3x0.5 thread, the air port is M5x0.8, and no magnet is fitted on this version: the optional -S code is what enables CMSE / DMSE switch sensing. This model is discontinued; the current-production replacement is ACEJ12X35, a drop-in in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. As a sizing rule, plan on roughly 34 N (about 0.6 of the push rating) of real work at 0.5 MPa, enough to lift about 2.9 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X35-10 (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 ACPJ12X35-10 Is Used
Small-part ejection from plastic molds
The 25-35 mm trimmed stroke nudges finished clips or bushings off a mold face, with 56.5 N at 0.5 MPa ample for lightweight parts.
Semiconductor fixture clamping
A 10 mm adjustment window lets one cylinder serve several wafer-carrier sizes; add the -S magnet code if CMSE / DMSE position switches are needed.
Bottle-line reject pusher
Short 25-35 mm throws kick underweight containers off a narrow conveyor lane at speeds up to 500 mm/s, with the TPU bumper softening each end of travel.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X35-10 with the ACEJ12X35-10
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa versus 100.5 N for a 16 mm bore and 157.1 N for a 20 mm bore, so step up if your part weight or friction load approaches 34 N of working demand. The 35 mm stroke sits inside the 50 mm maximum standard stroke for this bore, so it is a catalog item, not a made-to-order length. Match FA/FB flange or LB foot hardware to the ISO 21287 face, and if you need position feedback, order the -S variant - without it there is no magnet and no switch can be fitted. For new designs, specify ACEJ12X35 instead, the current ISO 21287 successor.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X35-10
- ✓ 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 ACPJ12X35-10 FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those rise to 79.2 N and 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. 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 air port is M5x0.8. The extend stroke is adjustable between 25 and 35 mm via the -10 stop screw.
An external stop screw shortens the extend stroke by up to 10 mm inside the ordered window, giving a usable 25-35 mm range; it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. The ACPJ family is discontinued - the current-production drop-in is ACEJ12X35 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint.
