This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X90-100SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X90-100SB 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 ACPJ12X90-100SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X90-100SB 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 ACEJ12X90-100SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X90-100SB
This AirTAC model is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 90 mm stroke on site within the ordered 100 mm window, so the usable range runs from 0 to 90 mm. At 0.5 MPa the 12 mm bore delivers 56.5 N push and 42.4 N pull, rising to 79.2 N push at 0.7 MPa. The 90 mm stroke exceeds the 50 mm standard limit for this bore, so it is a made-to-order build. Note this model is discontinued; the current-production replacement is ACEJ12X90.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which suits cramped jigs and guarding where a full-length body will not fit. The -S code on this unit carries the magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing. A fixed TPU bumper sits at both ends, and the male rod thread (B code) takes external knuckles directly. As a rule of thumb, plan on roughly 34 N of usable push at 0.5 MPa, which lifts about 2.8 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X90-100SB (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 ACEJ12X90-100SB 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 ACPJ12X90-100SB Is Used
Small-part ejection from fixtures
The 56.5 N push at 0.5 MPa is enough to kick machined bushings or clips off a jig, and the adjustable stop lets you set the exact ejection distance per fixture.
Position-verified test stations
With the -S magnet fitted, CMSE or DMSE switches confirm the rod has reached the trimmed position, useful in electronics assembly go/no-go checks.
Light clamping in tight enclosures
The short body, about 50% shorter than an ISO 15552 profile cylinder, fits inside compact test rigs where a 34 N clamping force on small housings is sufficient.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X90-100SB with the ACEJ12X90-100SB
Size against neighbours: the 16 mm bore gives 100.5 N push at 0.5 MPa if you need more force, while stepping down is not possible since 12 mm is the smallest bore in this family. The stop screw shortens the extend stroke only - it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost and it must never be relied on to hold a load. FA/FB flange and LB foot mountings bolt to the standard face, and the male rod thread suits I/Y knuckles. Because this model is discontinued, order ACEJ12X90 as the drop-in successor and confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X90-100SB
- ✓ 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 ACPJ12X90-100SB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa push rises to 79.2 N, and the theoretical maximum is 11.5 kgf at 1.0 MPa. The -100 code is a 100 mm adjustment window: the stop screw shortens the 90 mm extend stroke on site, giving a usable range of 0-90 mm. The 90 mm stroke is a made-to-order build because the standard maximum for a 12 mm bore is 50 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
Order ACEJ12X90, the current-production ISO 21287 successor: swap the P for an E and you get the same 12 mm bore, 90 mm stroke and force class in a matching short body. Before swapping, confirm the ISO 21287 mounting dimensions against your fixture, because the ACPJ was built to a DIN-standard footprint. The ACEJ keeps the same mounting family (FA/FB flange, LB foot) and supports the optional -S magnet for CMSE / DMSE switches.
