This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X175-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X175-75S in place of this model. 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 ACPJ12X175-75S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X175-75S is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 175mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X175-75S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X175-75S
Double acting and adjustable in stroke, this discontinued ACPJ12X175-75S runs a 12 mm bore over a 175 mm stroke that a stop screw can trim by up to 75 mm, giving a usable extend range of 100-175 mm. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N push at 0.7 MPa, with a theoretical ceiling of 11.5 kgf at 1.0 MPa. The S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling.
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 where a full-length body will not reach. A hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and the rod ends in a female M3x0.5 thread with M5x0.8 ports. As a planning figure, expect roughly 34 N (about 3.5 kg) of real work at 0.5 MPa, and a vertical lift of about 2.9 kg with a 2:1 margin. Note the 175 mm stroke exceeds the 50 mm standard for this bore, so it is made to order, and the series is discontinued: the current drop-in is ACEJ12X175, with ISO 21287 mounting dimensions to confirm before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X175-75S (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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | 59 N |
| Max (@1.0 MPa) | 12 kgf | |
The ACEJ12X175-75S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X175-75S Is Used
Signalled eject on a small assembly station
The fitted magnet lets a CMSE switch confirm the trimmed extend position, so a 100-175 mm adjustable stroke can kick small plastic housings off a nest only when the PLC sees the sensor made.
Part-present pusher in a compact jig
With about 34 N of usable push at 0.5 MPa, the 12 mm bore nudges light aluminium caps into a locating fixture inside a guard where a full-length body would not fit.
Sample lift in a lab dosing head
A vertical lift of roughly 2.9 kg with a 2:1 margin suits raising small sample trays or vial racks, with the female M3x0.5 rod thread taking a custom tooling adapter.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X175-75S with the ACEJ12X175-75S
At 12 mm bore this is the lightest force class: 56.5 N push at 0.5 MPa. If the load stalls or needs more margin, step up to the 16 mm bore (100.5 N push at 0.5 MPa) or the 20 mm bore (157.1 N). Going smaller is not possible in this family. The 75 mm window trims the extend stroke only; it is a mechanical end stop, not a mid-stroke lock, so on air loss the piston still drifts and no load should be held by the stop alone. FA/FB flange and LB foot mountings plus I/Y rod knuckles suit standard fixture plates, and the fitted -S magnet pairs with CMSE / DMSE switches. For new projects, order the current ACEJ12X175 instead and confirm ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X175-75S
- ✓ 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 ACPJ12X175-75S FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa push is 79.2 N and pull 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. It is double acting with a 75 mm adjustment window on the 175 mm stroke (usable range 100-175 mm), speed 30-500 mm/s, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), M5x0.8 ports, a female M3x0.5 rod thread and fixed TPU bumpers at both ends. The 175 mm stroke is a made-to-order length, since the standard maximum for this bore is 50 mm.
This ACPJ12X175-75S is no longer in production. The current drop-in is the ISO 21287 ACEJ12X175 (swap the P for an E), which matches the same bore, stroke and force class with a short body and mounting family. Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping. The -S magnet on this unit carries CMSE / DMSE switch compatibility; on the ACE the magnet is the optional -S code.
