This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X175-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X175-30S 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 ACPJ12X175-30S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X175-30S 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 ACEJ12X175-30S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X175-30S
This is a double acting, adjustable-stroke compact cylinder in the discontinued AirTAC ACPJ series. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa (rising to 79.2 N push at 0.7 MPa), and the -30 code gives a 30 mm adjustment window: a stop screw trims the extend stroke anywhere within 145-175 mm on site. The 175 mm stroke is non-standard for this bore (max standard is 50 mm), so it is made to order. The hard-anodized aluminium body with an S45C hard-chrome rod keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body cannot.
The -S code on this model means the optional magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the body for end-of-stroke sensing. A fixed TPU bumper sits at both ends to soften approach. In practice, plan on about 33.9 N of usable push at 0.5 MPa (roughly 0.6 of the rating), which lifts about 2.9 kg vertically with a 2:1 margin. Note that ACPJ is discontinued: the current-production drop-in is ACEJ12X175, same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping, since ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X175-30S (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 ACEJ12X175-30S 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 ACPJ12X175-30S Is Used
Position-verified slide on a small assembly press
The fitted magnet feeds CMSE switch signals to the PLC so the 145-175 mm trimmed extend stroke is confirmed before a 2.9 kg part is nudged into a locating nest.
Short-body ejector in a compact jig
The 50%-shorter-than-ISO-15552 body fits inside a cramped electronics fixture, using about 33.9 N of usable push at 0.5 MPa to kick finished PCB carriers off the nest.
Stop-and-sort gate on a labelling line
A 30 mm trimmed window (145-175 mm) sets the exact gate throw, while the 42.4 N pull at 0.5 MPa retracts the blade against light carton back-pressure.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X175-30S with the ACEJ12X175-30S
Size both ways before ordering: the 16 mm bore gives 100.5 N push at 0.5 MPa if your load creeps past what this 12 mm unit can move, while stepping down is not possible since 12 mm is the smallest bore in the family. The stop screw is a mechanical end stop for the extend stroke only - it shortens travel, it is not a mid-stroke lock, and the piston still drifts if air is lost. Match FA/FB flange or LB foot mounts and I/Y rod knuckles to your fixture, and remember the female M3x0.5 rod thread on this model. For new designs, order ACEJ12X175 instead, as ACPJ is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X175-30S
- ✓ 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 ACPJ12X175-30S FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa that rises to 79.2 N push and 59.4 N pull. Theoretical maximum is 11.5 kgf at 1.0 MPa. As a working figure, budget about 33.9 N (0.6 of the push rating) for real work, which lifts roughly 2.9 kg vertically with a 2:1 margin. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s.
The -30 code is a 30 mm window: an external stop screw shortens the 175 mm extend stroke on site, giving a usable range of 145-175 mm - it trims travel, it never lengthens it, and it is not a load-holding lock. This ACPJ is discontinued; the current-production drop-in is ACEJ12X175 (ISO 21287, same bore, stroke and force class). Confirm the ISO 21287 mounting dimensions before swapping, because ACP is DIN-standard. The -S magnet on this unit accepts CMSE / DMSE switches; on replacements order the -S code again to keep sensing.
