This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X150-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X150-30 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 ACPJ12X150-30
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-30 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 ACEJ12X150-30 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-30
This is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 150 mm stroke by up to 30 mm on site, giving a usable range of 120-150 mm. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 N / 59.4 N at 0.7 MPa, 11.5 kgf theoretical maximum), enough for light clamping and positioning in tight fixtures. The 150 mm stroke is longer than the 50 mm standard maximum for this bore, so it is a made-to-order build - plan lead time accordingly.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim jigs and guarding where a full-length body will not fit. A fixed TPU bumper sits at both ends and only decelerates the piston at the extremes - it never locks or holds a load, so on air loss the rod drifts. Note this model carries no magnet (the optional -S code adds one for CMSE / DMSE switches). The ACPJ family is discontinued; the current drop-in is ACEJ12X150, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X150-30 (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 ACEJ12X150-30 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 ACPJ12X150-30 Is Used
Micro-part ejection from machining fixtures
The 56.5 N push at 0.5 MPa is enough to eject small turned or milled parts off a locating pin, and the 30 mm trim window lets the operator dial the eject travel between 120 and 150 mm without changing the cylinder.
Compact pick-and-place gantry axis
With about 2.9 kg of vertical lift capacity at a 2:1 margin, this bore suits lightweight gripper slides on slim gantries; the short body saves roughly half the mounting length of an ISO 15552 profile cylinder in the Z axis.
Lab dosing and sample press station
Light pressing of vials, caps and sample trays needs only tens of newtons; the 79.2 N push at 0.7 MPa covers it with headroom, and the FA flange bolts the cylinder flat against a compact backplate.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-30 with the ACEJ12X150-30
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa. If your load needs more, step up to the 16 mm bore (100.5 N push at 0.5 MPa) or the 20 mm bore (157.1 N). For real work plan on roughly 34 N - about 3.5 kg - rather than the full rating, and treat the vertical-lift equivalent as about 2.9 kg with a 2:1 margin. The adjuster is a mechanical end stop for the extend stroke only, not a mid-stroke lock. Mounting is FA/FB flange or LB foot; the rod end is female M3x0.5 and ports are M5x0.8. Order the -S variant if you need magnet-based CMSE / DMSE sensing. Since ACPJ is discontinued, spec the ACEJ12X150 as the current-production equivalent and verify ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X150-30
- ✓ 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 ACPJ12X150-30 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 ordered stroke is 150 mm and the -30 code gives a 30 mm adjustment window, so a stop screw trims the extend stroke anywhere in a 120-150 mm range. The 150 mm stroke is non-standard for this bore (standard maximum is 50 mm), so it is made to order.
It is a short-body compact cylinder with a hard-anodized aluminium body, an S45C hard-chrome 6 mm rod, M5x0.8 ports and a fixed TPU bumper at both ends that only decelerates the piston at the ends. Position sensing requires the optional -S magnet code, which allows CMSE / DMSE switches; this model has no magnet fitted. The ACPJ is discontinued - the current-production replacement is ACEJ12X150, so confirm ISO 21287 mounting dimensions before swapping.
