This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X150-100SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X150-100SB 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 ACPJ12X150-100SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-100SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X150-100SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-100SB
A double acting compact cylinder with an adjustable stroke, the ACPJ12X150-100SB runs a 12 mm bore over a 150 mm stroke that a stop screw can trim by up to 100 mm, giving a usable extend range of 50-150 mm. Push force is 56.5 N and pull 42.4 N at 0.5 MPa, rising to 79.2 N at 0.7 MPa, with a theoretical ceiling of 11.5 kgf at 1.0 MPa. The 150 mm stroke exceeds the 50 mm standard maximum for this bore, so it is a made-to-order build. Note this model is discontinued: the current-production replacement is the ACEJ12X150, and buyers should confirm ISO 21287 mounting dimensions before swapping since the ACP is DIN-standard.
The hard-anodized aluminium body with an S45C hard-chrome rod keeps the short ISO 21287 footprint, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder - useful in slim fixtures and guarded cells. Because the -S magnet is fitted on this model, CMSE / DMSE reed or solid-state switches can be mounted directly. As a rule of thumb, plan for about 34 N (roughly 3.4 kg of force equivalent) of real work at 0.5 MPa, or about 2.8 kg of vertical lift with a 2:1 margin. Speed range is 30-500 mm/s and the fixed TPU bumper at both ends decelerates the rod at each end of travel.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X150-100SB (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 ACEJ12X150-100SB 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 ACPJ12X150-100SB Is Used
Small-part ejection on assembly stations
The 50-150 mm adjustable extend range lets a line technician trim the push-off stroke to clear a machined bushing or connector from a nest without re-plumbing the fixture.
Position-verified test fixtures
With the -S magnet fitted, CMSE or DMSE switches confirm full extension of a 150 mm probe or gauge stroke on an electronics test bench, cutting scrap from mis-seated parts.
Light lid press on lab packaging
About 2.8 kg of vertical lift margin at 0.5 MPa is enough to snap-close small blister or vial lids in a compact medical packaging cell where a full-length cylinder will not fit.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-100SB with the ACEJ12X150-100SB
At 56.5 N push (42.4 N pull) at 0.5 MPa, this 12 mm bore suits light clamping and positioning; step up to the 16 mm bore (100.5 N push) when loads approach 6 kg, or drop to a smaller direct-acting unit for lighter work. The male rod thread (B code) pairs with I/Y knuckles, and FA flange or LB foot mounts bolt to the ISO 21287 face. The adjuster is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so add a separate valve or lock for load holding. Order the ACEJ12X150 as the current drop-in successor.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X150-100SB
- ✓ 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 ACPJ12X150-100SB FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa push is 79.2 N and pull 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The -100 code is a 100 mm adjustment window: an external stop screw shortens the 150 mm extend stroke on site, so the usable range is 50-150 mm. It shortens the stroke only - it never extends it past the ordered length, and it is not a mid-stroke lock, so the piston still drifts if air is lost.
This is a short-body ISO 21287 compact cylinder with a hard-anodized aluminium body, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends and a male rod thread (B code). The optional -S magnet is fitted on this model, so CMSE and DMSE reed or solid-state switches mount directly on the body. The model is discontinued; the ACEJ12X150 is the current-production replacement - confirm ISO 21287 mounting dimensions before swapping.
