This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X150-20SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X150-20SB 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 ACPJ12X150-20SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-20SB 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 ACEJ12X150-20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-20SB
This double acting compact cylinder carries the -S magnet and a male rod thread on a 12 mm bore with a 150 mm made-to-order stroke. The -20 code gives a 20 mm adjustment window, so an external stop screw trims the extend stroke anywhere in a 130-150 mm range on site. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those figures rise to 79.2 N and 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding where a full-length body cannot.
Plan on about 34 N (roughly 3.5 kgf) of real work at 0.5 MPa rather than the full rating, and expect it to lift about 2.9 kg vertically with a 2:1 margin. The hard-anodized aluminium body pairs with an S45C hard-chrome rod and fixed TPU bumpers at both ends, running 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). Note that this model is discontinued: the current-production replacement is ACEJ12X150, so confirm ISO 21287 mounting dimensions before swapping, since the ACP family was built to a DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X150-20SB (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 ACEJ12X150-20SB 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 ACPJ12X150-20SB Is Used
Position-flagged ejector on a small assembly station
The fitted -S magnet lets a CMSE switch confirm the trimmed 130-150 mm extend position, while the stop screw dials the push-off travel to clear a 40 mm-deep fixture pocket.
Light clamp on a PCB test fixture
About 34 N of usable force at 0.5 MPa is enough to hold a circuit board against locating pins, and the short body fits inside the fixture lid where a full-length cylinder will not.
Sample pusher in a compact lab analyzer
The male rod thread drives a small slide that advances a sample vial about 2.9 kg equivalent vertical load, with the M5x0.8 ports keeping tubing runs tidy in tight panels.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-20SB with the ACEJ12X150-20SB
At 12 mm bore this is the smallest force class in the range: the 16 mm bore pushes 100.5 N at 0.5 MPa and the 20 mm bore reaches 157.1 N, so step up if 56.5 N is marginal for your load. The stop screw only shortens the extend stroke within the 20 mm window and drifts on air loss, so it is not a mid-stroke lock for holding a load. FA/FB flange and LB foot mountings bolt to the standard face, and because the -S magnet is fitted on this unit, CMSE or DMSE switches can be added directly. Order ACEJ12X150 as the current drop-in successor.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X150-20SB
- ✓ 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 ACPJ12X150-20SB 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 -20 code sets a 20 mm adjustment window: an external stop screw shortens the 150 mm extend stroke, giving a usable 130-150 mm range. The 150 mm stroke is non-standard for this 12 mm bore (standard tops out at 50 mm), so it is made to order. The stop is a mechanical end stop only and does not hold a load if air is lost.
No - the ACPJ family is discontinued. The current-production drop-in is ACEJ12X150, which matches the same 12 mm bore, 150 mm stroke and force class in the ISO 21287 short-body format. Because the ACP was built to a DIN-standard footprint, confirm the ISO 21287 mounting dimensions against your fixture before ordering. This unit carries the optional -S magnet for CMSE / DMSE switches, a male rod thread, PT ports at M5x0.8, and fixed TPU bumpers at both ends.
