This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X150-75, 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 ACPJ12X150-75
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X150-75 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X150-75 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-75
A double acting compact cylinder in the DIN-standard ACP family, the ACPJ12X150-75 pairs a 12 mm bore with a 150 mm stroke and a 75 mm adjustment window: an external stop screw trims the extend stroke anywhere in the 75-150 mm range on site. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N at 0.7 MPa. The 150 mm stroke exceeds the 50 mm standard maximum for this bore, so it is a made-to-order build. Note this model is discontinued; the current-production replacement is the ACEJ12X150.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and guarding where a full-length body will not fit. A hard-anodized aluminium body carries an S45C hard-chrome rod, with a fixed TPU bumper at each end and speeds of 30-500 mm/s. In practice, plan for roughly 34 N (about 3.4 kg of thrust) of real work at 0.5 MPa, and expect it to lift about 2.9 kg vertically with a 2:1 margin. No magnet is fitted, so position switches cannot be used unless you order the optional -S magnet version.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X150-75 (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 ACPJ12X150-75 Is Used
Small-part ejection in plastic moulding
The 56.5 N push at 0.5 MPa is enough to kick light sprues or finished caps off a mould table, and the 75-150 mm adjustable reach lets one cylinder serve several mould heights.
Sample press in a lab automation cell
With about 2.9 kg of vertical lift capability at a 2:1 margin, it presses microplate lids or seals sample trays in compact benchtop instruments where space is scarce.
Carton flap tuck on a packaging line
The trimmed extend stroke stops the rod exactly at the flap, and the fixed TPU bumpers decelerate the 6 mm rod gently at each end during 30-500 mm/s cycling.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-75 with the ACEJ12X150-75
Size against neighbours: the 16 mm bore delivers 100.5 N push at 0.5 MPa if 56.5 N is marginal, while stepping down is not possible below 12 mm in this family. The adjuster is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, so on air loss the rod can drift; do not use it to hold a load. Mounting is FA/FB flange or LB foot on the standard face. This unit is discontinued; order the ACEJ12X150 and confirm ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN standard.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X150-75
- ✓ 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 ACPJ12X150-75 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. The -75 code gives a 75 mm adjustment window, so the external stop screw can trim the 150 mm extend stroke anywhere down to 75 mm. The 150 mm stroke is a made-to-order length because the bore 12 standard maximum is 50 mm.
It is a short-body compact cylinder with a hard-anodized aluminium body, an S45C hard-chrome 6 mm rod, an M5x0.8 air port, a female M3x0.5 rod thread and a fixed TPU bumper at both ends, running on 0.15-1.0 MPa (22-145 psi) filtered air. Its body saves about 50% of the mounting length of an ISO 15552 profile cylinder. The model is discontinued: the current drop-in is the ACEJ12X150, so confirm the ISO 21287 mounting dimensions before you swap. Position sensing needs the optional -S magnet ordered with CMSE or DMSE switches; this version has no magnet fitted.
