This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X100-75B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X100-75B 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 ACPJ12X100-75B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-75B 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 ACEJ12X100-75B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-75B
The ACPJ12X100-75B is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 100 mm stroke by up to 75 mm, giving a usable range of 25-100 mm. Air works on both faces of the 12 mm piston, so at 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N and 59.4 N at 0.7 MPa. The 100 mm stroke exceeds the 50 mm standard limit for this bore, so it is a made-to-order build. This model is discontinued; the current-production replacement is the ACEJ12X100, a drop-in ISO 21287 successor in the same bore, stroke and force class.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs, guards and gantries. A fixed TPU bumper sits at both ends, and the hard-anodized aluminium body carries an S45C hard-chrome 6 mm rod with a male thread (the B code). Because there is no S in this code, no magnet is fitted, so CMSE / DMSE switches cannot be used; order the -S variant if sensing is needed. As a sizing rule of thumb, plan on roughly 34 N of real work at 0.5 MPa, which lifts about 2.9 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X100-75B (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 ACEJ12X100-75B 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 ACPJ12X100-75B Is Used
Small-part ejection from press dies
A 34 N usable push at 0.5 MPa is enough to strip light aluminium stampings off a die, and the 25-100 mm trim range lets one cylinder serve several die heights.
Lab sample indexing on micro-automation lines
The short body fits inside compact analytical and diagnostic equipment, and the male-threaded 6 mm rod bolts straight to custom tooling plates.
Vertical lowering of sensor carriages
With about 2.9 kg of vertical lift capacity at a 2:1 margin, it lowers lightweight camera or sensor heads in inspection gantries; add the -S magnet code if position switches are required.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-75B with the ACEJ12X100-75B
If 56.5 N of push at 0.5 MPa is marginal for your jig, step up to the 16 mm bore for 100.5 N; if the load is under about 20 N, the same 12 mm bore in a shorter fixed-stroke ACP may be cheaper. The stop screw only shortens the extend stroke and is not a mid-stroke lock: on air loss the piston still drifts, so do not rely on it to hold a load. Match FA/FB flange or LB foot hardware to the ISO 21287 face, and confirm the ISO 21287 mounting dimensions of the ACEJ12X100 before swapping from this discontinued DIN-standard model.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X100-75B
- ✓ 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 ACPJ12X100-75B FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.2 N and pulls 59.4 N. The theoretical maximum is 11.5 kgf at 1.0 MPa. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), from -20 to +70 C at 30-500 mm/s.
The -75 code is a 75 mm adjustment window: an external stop screw shortens the 100 mm extend stroke on site, so the effective range is 25-100 mm; it cannot lengthen the stroke past 100 mm. The fixed TPU bumpers only decelerate at the ends. This model is discontinued - the ACEJ12X100 is the current ISO 21287 drop-in, so confirm its mounting dimensions before swapping.
