This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X80-75SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X80-75SB 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 ACPJ12X80-75SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-75SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 80mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X80-75SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-75SB
This AirTAC ACPJ12X80-75SB is a double acting compact cylinder with an adjustable extend stroke: the -75 stop screw trims the 80 mm stroke anywhere down to 5 mm on site, so one unit covers a 5-80 mm working range. Air feeds through M5x0.8 ports at 0.15-1.0 MPa (22-145 psi), rod speed runs 30-500 mm/s, and fixed TPU bumpers sit at both ends. 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.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits slim pick-and-place heads and cramped fixture plates. Because the -S magnet is fitted on this model, CMSE / DMSE reed or solid-state switches can be mounted directly on the hard-anodized aluminium body. For sizing, treat roughly 34 N (about 0.6 of the 56.5 N push) as the practical working force at 0.5 MPa, enough to lift about 2.8 kg vertically with a 2:1 margin. Note the 80 mm stroke exceeds the 50 mm standard limit for bore 12, so it is a made-to-order build, and the ACPJ family is discontinued - the current drop-in is the ACEJ12X80, with ISO 21287 mounting dimensions to confirm before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X80-75SB (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 ACEJ12X80-75SB 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 ACPJ12X80-75SB Is Used
Micro part ejection from press dies
The 56.5 N push at 0.5 MPa nudges small stamped clips off a die face, and the 5-80 mm adjustable window lets the operator dial the ejector travel without swapping cylinders.
Position-verified gate on a lab feeder
With the fitted -S magnet, a CMSE switch confirms the rod is fully forward before the next vial advances, at speeds up to 500 mm/s.
Low-force clamping of PCB fixtures
About 34 N of practical clamping force at 0.5 MPa holds thin circuit boards in a test nest without marking the substrate, inside a body roughly half the length of an ISO 15552 profile cylinder.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-75SB with the ACEJ12X80-75SB
At 12 mm bore you get 56.5 N push at 0.5 MPa; step up to the 16 mm bore for 100.5 N or drop to the smallest frame only if your part weighs under about 2.8 kg lifted vertically. The stop screw shortens the extend stroke only - it is an end stop, not a mid-stroke lock, so the piston still drifts if air is lost. The male rod thread (B code) pairs with I/Y knuckles, and FA flange or LB foot mounts bolt to the same face. Order the ACEJ12X80 as the current-production replacement and verify its ISO 21287 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X80-75SB
- ✓ 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 ACPJ12X80-75SB 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 and 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The 12 mm bore uses M5x0.8 ports, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), and moves at 30-500 mm/s between -20 and +70 C. The 80 mm stroke is a made-to-order length because the bore 12 standard maximum is 50 mm.
The -75 code means an external stop screw shortens the 80 mm extend stroke by up to 75 mm, giving a usable 5-80 mm range; it acts as a mechanical end stop only and never holds a load if air pressure drops. This ACPJ is discontinued - the current-production successor is the ACEJ12X80 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before the swap, since the ACP was built to a DIN-standard footprint.
