This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X110-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X110-100S 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 ACPJ12X110-100S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-100S 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 ACEJ12X110-100S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-100S
This compact AirTAC cylinder is double acting, with air extending and retracting the rod, and carries a 100 mm adjustment window: a stop screw trims the 110 mm extend stroke anywhere down to 10 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. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped fixtures and guarding where a full-length body cannot.
The 110 mm stroke exceeds the 50 mm standard maximum for this bore, so it is a made-to-order build. Plan on about 34 N of real work at 0.5 MPa (roughly 60% of the rated push), which corresponds to lifting about 3 kg vertically with a sensible margin. The -S code on this model means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly. Note this ACPJ series is discontinued; the current-production drop-in is the ACEJ12X110, and buyers should confirm ISO 21287 mounting dimensions before swapping since the ACP follows a DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X110-100S (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 ACEJ12X110-100S 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 ACPJ12X110-100S Is Used
Micro part ejection from press dies
The 56.5 N push at 0.5 MPa is enough to strip small stamped terminals or connector pins off a die, and the trimmable 10-110 mm range lets one unit serve several die heights.
Position-verified slide on a test bench
With the fitted magnet and a CMSE or DMSE switch, the 110 mm travel can signal home and end positions on an electronics inspection fixture running at 30-500 mm/s.
Sample pusher in lab automation
The short body, about 50% shorter than an ISO 15552 profile cylinder, fits inside compact analytical or sample-handling enclosures where the 42.4 N pull is ample for tray indexing.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-100S with the ACEJ12X110-100S
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, so step up if your part weight or clamp force approaches the upper end. The 100 mm window lets one cylinder serve several stroke positions from 10 to 110 mm, but remember the stop screw only shortens the extend stroke and does not hold a load if air is lost. The female M3x0.5 rod thread accepts I/Y knuckles, and FA flange or LB foot mounts bolt to the face. If you need position feedback, this -S version already carries the magnet for CMSE / DMSE switches. For new projects order the ACEJ12X110 instead, as this model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X110-100S
- ✓ 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 ACPJ12X110-100S 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. In practice budget about 34 N for real work at 0.5 MPa, which is roughly a 3 kg vertical lift with margin. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed 30-500 mm/s.
The -100 code is a 100 mm window: an external stop screw shortens the 110 mm extend stroke to any value from 10 mm upward, though it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts on air loss. Both ends carry a fixed TPU bumper. This ACPJ series is discontinued; the current-production drop-in is the ACEJ12X110 in the same bore, stroke and force class, and you should confirm the ISO 21287 mounting dimensions before swapping because the ACP is DIN-standard.
