This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X110-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X110-20 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 ACPJ12X110-20
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-20 is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 110mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X110-20 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-20
A double acting compact cylinder with an adjustable extend stroke, the ACPJ12X110-20 uses a 12 mm bore to deliver 56.5 N of push force and 42.4 N of pull force at 0.5 MPa (rising to 79.2 N at 0.7 MPa). Its 110 mm stroke is a non-standard, made-to-order length for this bore, and the -20 code adds a 20 mm adjustment window: an external stop screw trims the extend stroke anywhere within 90-110 mm on site. The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body cannot. Note this ACPJ model is discontinued; the current-production replacement is ACEJ12X110.
Practical sizing: plan on about 34 N (roughly 3.4 kg of push) for real work at 0.5 MPa, which translates to lifting about 2.9 kg vertically with a 2:1 margin. The rod carries a female M3x0.5 thread, ports are M5x0.8, and a fixed TPU bumper at each end absorbs end-of-travel shock. No magnet is fitted on this version, so no position switch can be mounted; order the -S code if CMSE / DMSE sensing is needed. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X110-20 (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 ACEJ12X110-20 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 ACPJ12X110-20 Is Used
Carton kick-off on a packing line
The 56.5 N push at 0.5 MPa is enough to nudge a folded carton off a conveyor lane, and the 90-110 mm adjustable range lets the operator fine-tune the throw without changing cylinders.
Sample vial ejector in a lab autoloader
A 12 mm bore with a 6 mm rod fits inside compact analyzer frames, and the trimmed extend stroke positions vials precisely at the pick point.
Light gate latch on a small fixture
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, letting the latch sit behind a guard bracket where space is minimal.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-20 with the ACEJ12X110-20
At 12 mm bore this is the smallest force class in the family: 56.5 N push at 0.5 MPa versus 100.5 N for a 16 mm bore and 157.1 N for a 20 mm bore. Choose it for light clamping, ejecting or part-presenting under about 3.4 kg of effective load; step up to the 16 mm bore if your fixture needs more margin. The 110 mm stroke exceeds the 50 mm standard maximum for this bore, so it is built to order. The stop screw shortens the extend stroke only - it is a mechanical end stop, not a mid-stroke lock, so the rod will drift if air is lost. Mounting options are FA/FB flange or LB foot, and the female M3x0.5 rod thread accepts standard I/Y knuckles. For new projects, specify the ACEJ12X110, the ISO 21287 successor in the same bore, stroke and force class, and confirm mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X110-20
- ✓ 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 ACPJ12X110-20 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, with a theoretical maximum of 11.5 kgf at 1.0 MPa. For real work, plan on about 34 N of push at 0.5 MPa, which is roughly 2.9 kg of vertical lift with a 2:1 margin. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed runs 30-500 mm/s.
The -20 code means an external stop screw shortens the 110 mm extend stroke by up to 20 mm, giving a usable range of 90-110 mm; it cannot lengthen the stroke past 110 mm. The stop is a mechanical end stop, not a load-holding lock. This ACPJ model is discontinued - the current-production drop-in is ACEJ12X110 (ISO 21287), so confirm mounting dimensions before swapping.
