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

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X175-30
The ACPJ12X175-30 is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 175 mm stroke by up to 30 mm, giving a usable range of 145-175 mm. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 N / 59.4 N at 0.7 MPa, 11.5 kgf theoretical max at 1.0 MPa). As a rule of thumb, plan on about 34 N of real work at 0.5 MPa, which lifts roughly 2 kg vertically with a 2:1 margin. Note the 175 mm stroke is beyond the 50 mm maximum standard stroke for this bore, so it is a made-to-order build.
This model is discontinued; the current-production replacement is the ACEJ12X175, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACPJ is DIN-standard. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and the hard-anodized aluminium body with S45C hard-chrome rod carries fixed TPU bumpers at both ends. No magnet is fitted on this version; the optional -S code is required before CMSE / DMSE switches can be used.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X175-30 (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 ACEJ12X175-30 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 ACPJ12X175-30 Is Used
Lab sample ejector
Ejects 2 kg sample trays from a compact analyzer drawer within a 145-175 mm travel window set by the 30 mm stop screw.
Carton flag kicker
Kicks small cartons off a packaging conveyor with 56.5 N push at 0.5 MPa where a full-length cylinder will not fit.
Fixture presence check
With the optional -S magnet and a CMSE switch, confirms jig clamping position on a short-stroke assembly fixture.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X175-30 with the ACEJ12X175-30
Bore 12 is the smallest in the family; if 56.5 N push at 0.5 MPa is marginal, step up to bore 16 (100.5 N push) or bore 20 (157.1 N push) at the same pressure. Remember the -30 stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange or LB foot mounting bolts to the standard face, and adding the -S magnet code enables CMSE / DMSE switch sensing. For new projects, specify the ACEJ12X175 instead, as this ACPJ version is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X175-30
- ✓ 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 ACPJ12X175-30 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. The theoretical maximum is 11.5 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
It is a short ISO 21287-class compact cylinder whose body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with an M5x0.8 port, M3x0.5 female rod thread and fixed TPU bumpers at both ends. An external stop screw shortens the extend stroke by up to 30 mm within the ordered window, so travel is adjustable from 145 to 175 mm. This model is discontinued - order the ACEJ12X175 and confirm ISO 21287 mounting dimensions.
