This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X30-10S, 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 ACPJ12X30-10S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X30-10S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 30mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X30-10S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X30-10S
A double acting compact cylinder with an adjustable extend stroke, the ACPJ12X30-10S pairs a 12 mm bore with a 30 mm stroke and a 10 mm trim window: an external stop screw shortens the extend stroke on site anywhere in the 20-30 mm range. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N at 0.7 MPa. The hard-anodized aluminium body keeps the mounting length about 50% shorter than an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit.
Because the -S code is in this model, the magnet is fitted and CMSE / DMSE reed or solid-state switches can be clamped straight on for end-of-stroke signals. Plan on roughly 34 N of usable push at 0.5 MPa (about 60% of the rating), which lifts around 3 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production drop-in is the ACEJ12X30 in the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X30-10S (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 ACPJ12X30-10S Is Used
Small-part ejection from fixtures
Trims its 30 mm extend stroke down to 20 mm with the stop screw to nudge machined aluminium blanks off a jig plate, using the 56.5 N push at 0.5 MPa.
Position-verified clamping
With the fitted magnet driving CMSE or DMSE switches, a test bench confirms the clamp reached its trimmed stroke before the probe cycle starts.
Compact lab press station
The short body fits inside a benchtop enclosure where a full-length profile cylinder cannot, pressing sensor caps with about 3 kg of vertical lift margin.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X30-10S with the ACEJ12X30-10S
Size the load first: if your fixture needs more than about 34 N of working force at 0.5 MPa, step up to the 16 mm bore (100.5 N push) or the 20 mm bore (157.1 N push); if 56.5 N is generous, this 12 mm bore keeps the envelope smallest. The 10 mm window suits stations where the part height varies slightly and the extend stroke must be trimmed without changing cylinders. The stop screw is a mechanical end stop only - it does not hold a load if air is lost. FA/FB flange or LB foot mounts bolt to the ISO 21287 face. For new builds, order the ACEJ12X30 instead, since this ACPJ version is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X30-10S
- ✓ 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 ACPJ12X30-10S FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa, push is 79.2 N and pull 59.4 N; theoretical maximum is 11.5 kgf at 1.0 MPa. It is a 12 mm bore, 30 mm stroke double acting cylinder with a 10 mm adjustable window (usable extend stroke 20-30 mm), M5x0.8 ports, a 6 mm rod with female M3x0.5 thread, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and a fixed TPU bumper at both ends.
The ACPJ family is no longer in production. The current drop-in is the ACEJ12X30, made by swapping the P for an E: same 12 mm bore, 30 mm stroke and force class in the ISO 21287 compact format. Because the ACPJ was DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. If you also need position sensing on the replacement, order the -S code so the optional magnet is fitted for CMSE / DMSE switches.
