This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X60-20, 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 ACPJ12X60-20
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X60-20 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 60mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X60-20 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-20
The ACPJ12X60-20 is a double acting compact cylinder with an adjustable stroke: air powers both the extend and return strokes, and the -20 stop screw trims the 60 mm extend stroke by up to 20 mm on site, giving a usable range of 40-60 mm. At 0.5 MPa the 12 mm bore delivers 56.5 N push and 42.4 N pull; at 0.7 MPa that rises to 79.2 N push. In practice plan on roughly 34 N of real work at 0.5 MPa, which lifts about 3 kg vertically with a 2:1 margin. The 60 mm stroke exceeds the 50 mm maximum standard stroke for bore 12, so this is a made-to-order build. This model is discontinued; the current-production replacement is the ACEJ12X60, same bore, stroke and force class.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length cylinder will not fit. A hard-anodized aluminium body carries an S45C hard-chrome rod, with a fixed TPU bumper at both ends and a female M3x0.5 rod thread. Ports are M5x0.8, speed runs 30-500 mm/s, and pressure spans 0.15-1.0 MPa (22-145 psi). Note there is no magnet fitted on this version, so position switches cannot be mounted; order the -S code for that. Confirm ISO 21287 mounting dimensions before swapping to the ACEJ.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X60-20 (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 ACPJ12X60-20 Is Used
Fixture clamp for small brackets
A 40-60 mm trimmed extend stroke clamps aluminium brackets in a machining fixture, using about 34 N of usable force at 0.5 MPa so soft parts are not deformed.
Carton flap tucker on a packing line
The compact short body fits inside tight guarding beside a carton sealer, pushing flaps home at up to 500 mm/s with the stroke trimmed to match each box size.
Parts ejector from a gravity chute
Ejects small stamped parts from a chute at 56.5 N push; order the -S version with CMSE or DMSE switches when the PLC needs end-of-stroke confirmation.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-20 with the ACEJ12X60-20
Size this bore for light clamping and small-part ejection: 56.5 N push at 0.5 MPa suits loads up to about 34 N in continuous duty. If you need more, the 16 mm bore gives 100.5 N push at 0.5 MPa; for lighter work the same family starts at 12 mm. The stop screw is a mechanical end stop for the extend stroke only - it does not hold a load if air is lost. FA/FB flange and LB foot mountings bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches. Since ACPJ is discontinued, order the ACEJ12X60 as the drop-in successor and verify the ISO 21287 footprint first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X60-20
- ✓ 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 ACPJ12X60-20 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. Bore is 12 mm with a 6 mm rod, female M3x0.5 rod thread and M5x0.8 ports. 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, fluid air filtered to 40 um. The -20 code gives a 20 mm adjustment window, so the 60 mm extend stroke trims to 40-60 mm. This stroke is made to order since bore 12 tops out at 50 mm standard.
An external stop screw shortens the extend stroke within the ordered 20 mm window; it shortens only, never lengthens past 60 mm, and it is a mechanical end stop rather than a mid-stroke lock, so the rod still drifts if air is lost. A fixed TPU bumper decelerates at each end. The ACPJ family is discontinued; the current-production drop-in is the ACEJ12X60 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, because the ACP was built to a DIN standard.
