This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X90-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X90-10 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 ACPJ12X90-10
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X90-10 is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 90mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X90-10 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X90-10
The ACPJ12X90-10 is a double acting, adjustable-stroke compact cylinder in AirTAC's DIN-standard ACP family, now discontinued. Its 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa (rising to 79.2 N push at 0.7 MPa), with a theoretical peak of 11.5 kgf at 1.0 MPa. The 90 mm stroke exceeds the 50 mm maximum standard stroke for this bore, so it is a made-to-order build. A stop screw trims the extend stroke by up to 10 mm, giving a usable range of 80-90 mm on site.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures, guards and small gantries. Hard-anodized aluminium body, S45C hard-chrome rod, fixed TPU bumpers at both ends and M5x08 ports (M5x0.8) round out the spec. Plan on about 34 N of real work at 0.5 MPa (roughly 60% of the rating), which lifts about 2.8 kg vertically with a 2:1 margin. This unit has no magnet fitted; the optional -S code adds one for CMSE / DMSE switches. Replacement: ACEJ12X90, the current-production drop-in - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X90-10 (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 ACEJ12X90-10 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 ACPJ12X90-10 Is Used
Small-parts ejection in plastic molding
The 80-90 mm trimmed extend range pushes finished clips or bushings off a compact mold table, with 56.5 N of push at 0.5 MPa enough for lightweight parts.
Pick-and-place gantry on electronics lines
The short body fits under low gantry frames where an ISO 15552 profile cylinder will not; add the -S magnet code to run CMSE / DMSE switches for end-of-stroke confirmation.
Lab sample press fixture
About 2.8 kg of vertical lift capability with a 2:1 margin suits gentle pressing of vial caps or sensor lids, and the 10 mm stop screw lets technicians dial the stroke between 80 and 90 mm.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X90-10 with the ACEJ12X90-10
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa. Step up to the 16 mm bore for 100.5 N push, or drop to a fixed-stroke ACP/ACE if you never need to trim the stroke. The 90 mm stroke is non-standard for this bore (max standard 50 mm), so it is built to order. Note the adjuster is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so do not rely on it to hold a load. FA/FB flange and LB foot mountings bolt to the ISO 21287 face; order the -S code if you need CMSE / DMSE switch positions. Replacement is ACEJ12X90 - confirm ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X90-10
- ✓ 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 ACPJ12X90-10 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: a stop screw shortens the 90 mm extend stroke to any setting between 80 and 90 mm. It is a mechanical end stop, not a mid-stroke lock - on air loss the piston still drifts. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, with fixed TPU bumpers at both ends.
No. The ACPJ family is discontinued, and a 90 mm stroke exceeds the 50 mm standard maximum for bore 12, so this exact model was always a made-to-order item. The current-production replacement is the ACEJ12X90 (ISO 21287, same bore, stroke and force class). Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping, and order the -S code on the ACEJ if you need the magnet for CMSE / DMSE switches.
