This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X80-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X80-10S 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 ACPJ12X80-10S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-10S 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 ACEJ12X80-10S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-10S
This is a double acting, adjustable-stroke compact cylinder in the discontinued ACPJ series: 12 mm bore, 80 mm stroke, 6 mm rod, M5x0.8 ports and a female M3x0.5 rod thread. The -10 code adds a 10 mm adjustment window, so a stop screw trims the extend stroke on site anywhere between 70 and 80 mm. It is a short-body DIN-standard unit whose mounting length runs about 50% shorter than an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding where a full-length body will not fit. Note the 80 mm stroke exceeds the 50 mm maximum standard stroke for bore 12, so it is a made-to-order build.
At 0.5 MPa the piston 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 ceiling of 11.5 kgf at 1.0 MPa. Plan on roughly 34 N of real work at 0.5 MPa, which corresponds to lifting about 3 kg vertically with a 2:1 margin. The S code means the optional magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped on for end-of-stroke signals. A fixed TPU bumper sits at each end and the hard-anodized aluminium body carries an S45C hard-chrome rod. This model is discontinued: the current-production drop-in is ACEJ12X80, and you should confirm the ISO 21287 mounting dimensions before swapping, because the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X80-10S (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 ACEJ12X80-10S 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 ACPJ12X80-10S Is Used
Small-parts ejection in plastic moulding
A 56.5 N push at 0.5 MPa is enough to kick light moulded clips or caps off a nest, and the 70-80 mm adjustable range lets the operator dial the eject point without re-plumbing.
Position-flagged gating on an assembly bench
With the -S magnet fitted, a CMSE or DMSE switch confirms the trimmed extend position on a fixture that slides a connector housing under a press head.
Sample indexing in lab automation
The short body, about 50% the mounting length of an ISO 15552 profile cylinder, advances microplate trays 70-80 mm inside a compact analyser enclosure at 30-500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-10S with the ACEJ12X80-10S
Size against neighbours: the 16 mm bore delivers 100.5 N push at 0.5 MPa if 56.5 N is marginal, while staying at bore 12 keeps the M5x0.8 porting and the smallest envelope. Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock - on air loss the piston still drifts, so add a separate valve or clamp if you need position holding. The 80 mm stroke is non-standard for this bore and made to order. For new builds, order the ACEJ12X80 instead: same bore, stroke and force class, currently in production.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X80-10S
- ✓ 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 ACPJ12X80-10S FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa push rises to 79.2 N and pull to 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, fluid air filtered to 40 um. Porting is M5x0.8, rod thread female M3x0.5, and the extend stroke is trimmable by up to 10 mm via the stop screw.
Order the ACEJ12X80, the current-production ISO 21287 successor: swap the P for an E and you get the same 12 mm bore, 80 mm stroke and force class in a matching short body. Confirm the ISO 21287 mounting dimensions before the swap, since the ACP is DIN-standard, and check FA/FB flange or LB foot interfaces plus the optional -S magnet code if you run CMSE / DMSE switches.
