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

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-75B
This is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 110 mm stroke by up to 75 mm on site, giving a usable range of 35-110 mm. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 N / 59.4 N at 0.7 MPa), with a theoretical maximum of 11.5 kgf at 1.0 MPa. Note that the 110 mm stroke exceeds the 50 mm maximum standard stroke for this bore, so it is a non-standard, made-to-order unit.
The hard-anodized aluminium body with S45C hard-chrome rod keeps the mounting length about 50% shorter than an ISO 15552 profile cylinder, so it slots into tight jigs and gantries. In practice, plan on roughly 34 N of real work at 0.5 MPa (about 0.6 of the push rating), which lifts about 2.9 kg vertically with a 2:1 margin. This model is discontinued; the current-production drop-in is the ACEJ12X110 in the same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X110-75B (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 ACPJ12X110-75B Is Used
Ejector on a small PCB test fixture
The 35-110 mm adjustable range lets a technician trim the push stroke so a finished board clears the nest without overshooting the probe block, using the 56.5 N push at 0.5 MPa.
Part-present kickers in a compact assembly gantry
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so the cylinder fits between guard plates where a full-length body would not.
Sample pusher in a lab dosing station
About 2.9 kg of vertical lift capacity at a 2:1 margin is enough to advance small vial trays, and the 30-500 mm/s speed band matches gentle handling.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-75B with the ACEJ12X110-75B
At 12 mm bore you get 56.5 N push at 0.5 MPa; step up to the 16 mm bore for 100.5 N or down to the smallest size if the 42.4 N pull at 0.5 MPa already covers your return load. The 75 mm window suits fixtures where the stroke must be trimmed after installation - remember the stop is a mechanical end stop, not a mid-stroke lock, so the piston still drifts on air loss. The B code gives a male rod thread; the optional -S magnet enables CMSE / DMSE switches, but without it no sensor can be fitted. For new builds, order the ACEJ12X110 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X110-75B
- ✓ 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 ACPJ12X110-75B 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. The -75 code means a stop screw can shorten the 110 mm extend stroke by up to 75 mm, so the usable range is 35-110 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends. The 110 mm stroke is non-standard for this bore and made to order.
Only if you order the optional -S magnet code; this model has no magnet, so CMSE / DMSE reed or solid-state switches cannot be mounted without it. The ACPJ family is discontinued - the current-production replacement is the ACEJ12X110, a drop-in successor in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, because the ACP follows the DIN-standard compact format.
