This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X50-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X50-10 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 ACPJ12X50-10
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X50-10 is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 50mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X50-10 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X50-10
Double acting and adjustable, the ACPJ12X50-10 is a discontinued DIN-standard compact cylinder with a 12 mm bore and 50 mm stroke. Air drives the rod in both directions, and the -10 code gives a 10 mm trim window: a stop screw shortens the extend stroke on site, so the usable range is 40-50 mm. 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, with a theoretical ceiling of 11.5 kgf at 1.0 MPa. Plan on roughly 34 N (about 3 kg) of real work at 0.5 MPa rather than the full rating, which means it lifts about 2 kg vertically with a 2:1 margin.
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, pick stations and guarding where a full-length body will not fit. A hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Note that no magnet is fitted on this version, so no switch can be mounted; the optional -S code adds one for CMSE / DMSE sensors. This model is discontinued - the current-production drop-in is the ACEJ12X50, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X50-10 (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 ACEJ12X50-10 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 ACPJ12X50-10 Is Used
Small-parts ejection from plastic molds
A 12 mm bore pushing 56.5 N at 0.5 MPa is enough to kick light molded clips or caps off the core, and the 40-50 mm trim range lets the molder dial the eject position without re-plumbing.
Compact test-and-sort stations
Electronics benches use the short body where an ISO 15552 profile cylinder is too long; with the optional -S magnet, CMSE / DMSE switches confirm the trimmed end position on each cycle.
Label or gasket press on packaging lines
About 34 N of usable force at 0.5 MPa seats thin gaskets and labels on cartons, and the stop screw lets operators shorten the 50 mm stroke to match shallow product heights.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X50-10 with the ACEJ12X50-10
Size both ways: if 56.5 N at 0.5 MPa is marginal for your jig, step up to the 16 mm bore for 100.5 N; if the load is only a few newtons, the same bore in a shorter trim window saves cost. The adjuster is a mechanical end stop for the extend stroke only - it does not lock the piston, so on air loss the rod still drifts and a separate holding method is needed. Mounting is FA/FB flange or LB foot on the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches if you need end-position sensing. Since this unit is discontinued, order the ACEJ12X50 as the current replacement and verify the mounting footprint first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X50-10
- ✓ 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 ACPJ12X50-10 FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.2 N and pulls 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The -10 code is a 10 mm window: the stop screw trims the 50 mm extend stroke down to 40 mm, so the working range is 40-50 mm. Speed is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).
Sensing needs the optional -S magnet code, which allows CMSE / DMSE reed or solid-state switches; this standard version has no magnet, so no switch can be mounted. The ACPJ family is discontinued - the current-production drop-in is the ACEJ12X50 (swap the P for an E), which matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before converting.
