This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X120-10SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X120-10SB 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 ACPJ12X120-10SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X120-10SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 120mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X120-10SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X120-10SB
A double acting, adjustable-stroke compact cylinder, the ACPJ12X120-10SB pushes 56.5 N and pulls 42.4 N at 0.5 MPa (79.2 / 59.4 N at 0.7 MPa) from a 12 mm bore. The -10 code gives a 10 mm trim window: a stop screw shortens the 120 mm extend stroke on site, so the working range is 110-120 mm. This 120 mm stroke is above the 50 mm standard limit for bore 12, so it is a made-to-order build.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guards. A fixed TPU bumper sits at both ends, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the -S magnet this model carries accepts CMSE / DMSE switches. Plan on about 34 N of real work at 0.5 MPa, or roughly 2.9 kg of vertical lift with a 2:1 margin. Note: this model is discontinued; the current drop-in is ACEJ12X120 - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X120-10SB (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 ACEJ12X120-10SB 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 ACPJ12X120-10SB Is Used
Small-part ejection from plastic molds
The 56.5 N push at 0.5 MPa clears finished caps or connectors off a mold face, and the 10 mm trim window lets the setter dial the eject travel between 110 and 120 mm without shimming.
Indexing on an SMT feeder slide
With the -S magnet fitted, CMSE switches confirm home and advance on a PCB transfer slide, while the short body fits the 50%-shorter envelope beside the guide rail.
Light hold-down of aluminum extrusions
About 34 N of usable clamp force at 0.5 MPa holds thin-wall extrusion against a drill jig; the male rod thread bolts a knuckle straight to the hold-down arm.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X120-10SB with the ACEJ12X120-10SB
At 56.5 N push at 0.5 MPa this 12 mm bore suits light clamping and indexing; step up to the 16 mm bore (100.5 N push) if the load stalls, or down where space is tighter and force is ample. The male rod thread (B code) takes I/Y knuckles directly. If you need position signals, this unit already carries the optional -S magnet for CMSE / DMSE switches. Remember the stop screw trims the extend stroke only - it is not a mid-stroke lock, so the rod still drifts on air loss. Replacement: order ACEJ12X120, the current-production successor in the same force class.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X120-10SB
- ✓ 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 ACPJ12X120-10SB 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; theoretical maximum is 11.5 kgf at 1.0 MPa. The -10 code gives a 10 mm adjustment window, so the 120 mm extend stroke can be trimmed to 110-120 mm with the stop screw. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the 120 mm stroke is a made-to-order length (standard tops out at 50 mm for bore 12).
No - the ACPJ family is discontinued. The current-production drop-in is ACEJ12X120 (swap the P for an E), which matches the same bore, stroke and force class. Because the ACP is DIN-standard while the ACE follows ISO 21287, confirm the mounting dimensions against your fixture before swapping. This unit's -S magnet accepts CMSE / DMSE switches, and the fixed TPU bumpers at both ends simply decelerate the rod at each end of travel.
