This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X200-100, 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 ACPJ12X200-100
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X200-100 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 200mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X200-100 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-100
The ACPJ12X200-100 is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 200 mm stroke by up to 100 mm, giving a usable range of 100-200 mm. This 12 mm bore size delivers 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 N push at 0.7 MPa), running on 0.15-1.0 MPa (22-145 psi) filtered air at 30-500 mm/s. The 200 mm stroke exceeds the 50 mm maximum standard stroke for bore 12, so it is a non-standard, made-to-order build.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in slim pick-and-place heads and tight fixture pockets. A fixed TPU bumper sits at both ends and only decelerates the piston at stroke ends - it never locks or brakes a load, so the rod will drift if air is lost. No magnet is fitted on this version (the optional -S code adds one for CMSE / DMSE switches). Note: the ACPJ family is discontinued; the current-production replacement is the ACEJ12X200, so confirm ISO 21287 mounting dimensions before swapping. As a sizing rule, plan on roughly 34 N of real work at 0.5 MPa (about 0.6 of the push rating), which lifts about 2.8 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X200-100 (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 ACPJ12X200-100 Is Used
Micro part ejection from fixtures
The 56.5 N push at 0.5 MPa nudges small stamped or molded parts out of a jig nest, with the 100 mm window letting you tune the extend stroke from 100 to 200 mm on the machine.
Lab sample press and clamp
About 2.8 kg of vertical lift capacity with a 2:1 margin suits pressing sensor caps or vial lids on compact benchtop automation where a full-length cylinder will not fit.
Slim gantry z-axis actuation
The short body cuts mounting length by roughly half versus an ISO 15552 profile cylinder, ideal for lightweight z-strokes on electronics assembly gantries; add the -S magnet code if CMSE / DMSE switch feedback is needed later.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-100 with the ACEJ12X200-100
At 12 mm bore this is the lightest ACPJ force class: 56.5 N push at 0.5 MPa. Step up to the 16 mm bore for 100.5 N push or the 20 mm bore for 157.1 N if your part weight grows. The stop screw shortens the extend stroke only - it is not a mid-stroke lock, so do not rely on it to hold a vertical load with air off. Mounting is FA/FB flange or LB foot; the female M3x0.5 rod thread takes standard I/Y knuckles. This model is discontinued - order the ACEJ12X200 as the drop-in successor and verify the ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X200-100
- ✓ 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 ACPJ12X200-100 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; theoretical maximum is 11.5 kgf at 1.0 MPa. The 12 mm bore uses an M5x0.8 port and a 6 mm rod with a female M3x0.5 thread. Operating range 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, air filtered to 40 um. The 200 mm stroke is a made-to-order length above the 50 mm standard maximum for this bore.
The -100 code means a 100 mm adjustment window: an external stop screw shortens the extend stroke anywhere between 100 and 200 mm, but it cannot lengthen the stroke past the ordered 200 mm. The stop is a mechanical end stop only - on air loss the piston still drifts. The ACPJ series is discontinued; the current-production drop-in is the ACEJ12X200 (same bore, stroke and force class). Confirm the ISO 21287 mounting dimensions before swapping, since the ACPJ follows the DIN-standard footprint. This version has no magnet; order the -S code to enable CMSE / DMSE switches.
