This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X200-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X200-20 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 ACPJ12X200-20
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-20 is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 200mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X200-20 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-20
Double acting compact cylinder with an adjustable extend stroke, the ACPJ12X200-20 uses a 12 mm bore and a 200 mm stroke trimmed by a 20 mm external stop screw, giving a usable range of 180-200 mm. 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. The 200 mm stroke is longer than the 50 mm standard maximum for bore 12, so it is a made-to-order build. Note this model is discontinued - the current drop-in is ACEJ12X200.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim slides and guarded assemblies. In practice, plan on about 34 N (roughly 3.5 kg) of real pushing work at 0.5 MPa, and expect it to lift about 2.9 kg vertically once you keep a 2:1 margin. A fixed TPU bumper sits at both ends, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the rod end is female M3x0.5 with PT ports. No magnet is fitted; order the optional -S code if you need CMSE / DMSE switch sensing.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X200-20 (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 ACEJ12X200-20 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 ACPJ12X200-20 Is Used
Small-part ejection from plastic molds
The 56.5 N push at 0.5 MPa is enough to kick light molded caps or bushings off a fixture, and the 180-200 mm adjustable reach clears deep cavities.
PCB pallet press-down in electronics assembly
About 2.9 kg of vertical lift with a 2:1 margin seats connectors and holds boards flat during screw-driving, with the TPU bumper softening each touch-down.
Sample pusher in lab automation gantries
The short body, roughly 50% slimmer than an ISO 15552 profile cylinder, fits inside compact analysis cabinets where vials must be indexed 180-200 mm.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-20 with the ACEJ12X200-20
Size by force first: bore 12 gives 56.5 N push at 0.5 MPa, while a 16 mm bore reaches 100.5 N and a 20 mm bore 157.1 N at the same pressure - step up if your load exceeds about 34 N of usable force. The stop screw only shortens the extend stroke within the 20 mm window and is not a mid-stroke lock; on air loss the piston drifts, so add a separate holding valve if position must be kept. FA/FB flange and LB foot mountings suit fixture plates. Because this unit is discontinued, order ACEJ12X200 as the current replacement and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X200-20
- ✓ 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 ACPJ12X200-20 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, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The -20 code gives a 20 mm adjustment window, so the 200 mm extend stroke can be trimmed anywhere between 180 and 200 mm with the external stop screw. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s. The 200 mm stroke is a made-to-order length, since bore 12 normally tops out at 50 mm standard.
No - the ACPJ12X200-20 is discontinued. The current-production replacement is ACEJ12X200, which matches the same bore, stroke and force class; confirm the ISO 21287 mounting dimensions before swapping, because the ACP was built to a DIN-standard footprint. For sensing, the magnet is the optional -S code: this version has no magnet fitted, so no CMSE or DMSE switch can be mounted unless you order the -S variant. Mounting options are FA/FB flange and LB foot.
