This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X120-10B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X120-10B 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 ACPJ12X120-10B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X120-10B 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 ACEJ12X120-10B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X120-10B
The ACPJ12X120-10B is a double acting, adjustable-stroke compact cylinder in the discontinued AirTAC ACPJ series. Air drives the rod in both directions, and the -10 code gives a 10 mm stop-screw window that trims the 120 mm extend stroke down to 110 mm on site. This 12 mm bore pushes 56.5 N and pulls 42.4 N at 0.5 MPa, rising to 79.2 N at 0.7 MPa, with a theoretical peak of 11.5 kgf at 1.0 MPa. The 120 mm stroke exceeds the 50 mm standard maximum 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 slots into slim fixtures and guarded assemblies. A fixed TPU bumper sits at each end, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the B code gives a male rod thread with PT ports. Note the stop screw is a mechanical end stop only - on air loss the piston still drifts, so plan external stops for load holding. This model is discontinued; the current-production replacement is ACEJ12X120, and you should confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X120-10B (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 ACEJ12X120-10B 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 ACPJ12X120-10B Is Used
Small-parts ejector on an assembly jig
The 56.5 N push at 0.5 MPa is enough to kick light plastic or stamped parts off a nest, and the 10 mm trim lets you tune the eject travel to the fixture without re-plumbing.
Sample press in a lab or test rig
With about 2.9 kg of practical vertical push available at 0.5 MPa, this bore suits light dip-test or capping stations where a full-length actuator would not fit the bench frame.
Carton flap tucker on a packing line
Running at 30-500 mm/s, the 110-120 mm adjustable reach folds flaps on small cartons, and the compact body mounts where an ISO 15552 profile cylinder is too long.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X120-10B with the ACEJ12X120-10B
Size this bore by force: at 0.5 MPa the 12 mm bore delivers 56.5 N push, while the 16 mm bore reaches 100.5 N and the 20 mm bore 157.1 N. If your mechanism needs more than about 34 N of real work - roughly 0.6 of the rated push - step up to ACPJ16. The 6 mm rod with male thread (B code) suits knuckle or tooling attachments; FA/FB flange and LB foot mountings bolt to the same face. No magnet is fitted on this version, so position switches cannot be used - order the -S code for CMSE / DMSE sensing. Replacement: ACEJ12X120, confirm ISO 21287 dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X120-10B
- ✓ 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 ACPJ12X120-10B 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 stop-screw window, so the 120 mm extend stroke can be trimmed anywhere between 110 and 120 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, rod 6 mm with male thread. The 120 mm stroke is made to order since bore 12 tops out at 50 mm standard.
It is a short-body compact cylinder with a hard-anodized aluminium body, S45C hard-chrome rod, fixed TPU bumpers at both ends and FA/FB flange or LB foot mounting options. The body saves about 50% of the mounting length of an ISO 15552 profile cylinder. No magnet is included on this code, so CMSE / DMSE switches need the optional -S magnet version. The ACPJ series is discontinued - order ACEJ12X120 as the current drop-in and verify the ISO 21287 mounting dimensions before converting.
