This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X120-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X120-100 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 ACPJ12X120-100
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X120-100 is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 120mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X120-100 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X120-100
This is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 120 mm stroke by up to 100 mm, giving a usable range of 20-120 mm on site. 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, with a theoretical peak of 11.5 kgf at 1.0 MPa. Note that the 120 mm stroke exceeds the 50 mm standard maximum for this bore, so it is a made-to-order build.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into slim fixtures and guarding where a full-length body cannot. A fixed TPU bumper sits at both ends and simply decelerates the piston - it never locks or holds a load, so the rod can drift if air is lost. In practice, plan for roughly 34 N of real work at 0.5 MPa (about 60% of the rating), which lifts about 2.9 kg vertically with a 2:1 margin. This model is discontinued; the current-production replacement is ACEJ12X120 - confirm ISO 21287 mounting dimensions before swapping, since the ACP series follows a DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X120-100 (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 ACEJ12X120-100 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 ACPJ12X120-100 Is Used
Micro part ejection from small press dies
The 56.5 N push at 0.5 MPa is enough to strip light stamped clips or pins off a small die, while the 100 mm window lets the setter dial the eject position in without shimming.
Sample vial indexing on lab automation decks
With about 2.9 kg of vertical lift capacity at a 2:1 margin, the 12 mm bore advances vial trays and reagent racks in compact analyser enclosures where every millimetre of length counts.
Carton flap tucking on bench-top sealers
The 20-120 mm adjustable range covers varied carton heights on small packaging benches, and the fixed TPU bumpers keep end-of-travel noise down at speeds up to 500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X120-100 with the ACEJ12X120-100
At 12 mm bore this is the smallest force class in the family: 56.5 N push at 0.5 MPa. Step up to the 16 mm bore for 100.5 N push at the same pressure, or drop to a direct ACEJ12X120 if you need the same size in current production. The 100 mm adjustment window suits jobs where the final extend position is tuned during commissioning. FA/FB flange and LB foot mountings bolt to the standard face, and I/Y rod knuckles fit the M3x0.5 female rod thread. No magnet is fitted on this code, so position switches cannot be used - order the -S version if CMSE / DMSE sensing is needed later.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X120-100
- ✓ 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 ACPJ12X120-100 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 push and 59.4 N pull, with a theoretical maximum of 11.5 kgf at 1.0 MPa. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, with a 6 mm rod, M3x0.5 female thread and M5x0.8 ports. The 120 mm stroke is made to order because the bore 12 standard maximum is 50 mm.
The -100 code is a 100 mm adjustment window: an external stop screw shortens the extend stroke anywhere within it, so the effective range is 20-120 mm. It trims the stroke only - it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air pressure is lost. This ACPJ model is discontinued; the current drop-in is ACEJ12X120 in the ISO 21287 series. Confirm the ISO 21287 mounting dimensions before swapping, as the ACP follows a DIN-standard body.
