This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X100-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X100-10S 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 ACPJ12X100-10S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-10S is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X100-10S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-10S
This discontinued ACPJ12X100-10S is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 100 mm stroke by up to 10 mm on site, giving a usable range of 90-100 mm. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 N / 59.4 N at 0.7 MPa), running on 0.15-1.0 MPa (22-145 psi) air at 30-500 mm/s. The 100 mm stroke exceeds the 50 mm standard limit for this bore, so it is a made-to-order item.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures, slides and pick stations. A hard-anodized aluminium body carries an S45C hard-chrome 6 mm rod with a female M3x0.5 thread, and fixed TPU bumpers sit at both ends. Because the -S magnet is fitted, CMSE / DMSE reed or solid-state switches can be clamped straight onto the tube. Plan on roughly 34 N of real work at 0.5 MPa (about 0.6 of the push force), which lifts about 3 kg vertically - halve that for a 2:1 margin on a real part. This model is discontinued; the current-production drop-in is the ACEJ12X100 - confirm ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X100-10S (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 ACEJ12X100-10S 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 ACPJ12X100-10S Is Used
Small-part ejection from press dies
The 56.5 N push at 0.5 MPa is enough to kick light stamped parts off a die table, and the 90-100 mm adjustable range lets the operator dial the eject position without re-machining the stop.
Position-checked gate on an electronics assembly line
With the -S magnet fitted, a CMSE switch signals gate-open or part-present on a PCB transfer shuttle, while the compact body fits between conveyor frames where a full-length cylinder cannot.
Sample pusher in a lab autosampler
The 6 mm hard-chrome rod and M3x0.5 female thread drive a light sample tray through a 90-100 mm stroke at 30-500 mm/s, with TPU bumpers quieting the ends of each cycle.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-10S with the ACEJ12X100-10S
Size up or down by force: the 16 mm bore gives 100.5 N push at 0.5 MPa and the 20 mm bore 157.1 N, while this 12 mm unit suits light clamps and small slides at 56.5 N. The stop screw is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, so on air loss the rod still drifts; use a separate valve or lock for holding. FA/FB flange and LB foot mountings bolt to the ISO 21287 face. Order the ACEJ12X100 as the current replacement and verify the mounting footprint against your fixture first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X100-10S
- ✓ 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 ACPJ12X100-10S 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. It is double acting with a 10 mm adjustment window on the 100 mm extend stroke, 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, M5x0.8 ports and a female M3x0.5 rod thread. The 100 mm stroke is a made-to-order length above the 50 mm standard for this bore.
It is a compact short-body cylinder whose mounting length is about 50% less than an ISO 15552 profile cylinder, with FA/FB flange and LB foot options on the ISO 21287 face and fixed TPU bumpers at both ends. The ACPJ family is discontinued; the current-production drop-in is the ACEJ12X100 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, because the ACP is DIN-standard.
