This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X150-75SB, the same code under the new prefix. 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 ACPJ12X150-75SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X150-75SB is a double acting, double rod, 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 ACEJ12X150-75SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-75SB
A double acting compact cylinder with an adjustable extend stroke, the ACPJ12X150-75SB carries a 12 mm bore and a 150 mm stroke trimmed by a 75 mm stop-screw window, so the usable range is 75-150 mm. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa that rises to 79.2 N push. The 150 mm stroke exceeds the 50 mm standard limit for bore 12, so it is a made-to-order build. This model is discontinued; the current drop-in is ACEJ12X150, same bore, stroke and force class.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which helps in slim fixtures and guard-mounted tooling. The -S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signals. The B code gives a male 6 mm rod thread, and the fixed TPU bumper at each end only decelerates at the ends. For sizing, plan on about 34 N of real work at 0.5 MPa, and expect roughly 2.9 kg of vertical lift with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X150-75SB (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 kgf |
ACPJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-75SB Is Used
Signalled ejection in assembly cells
The fitted magnet lets a CMSE switch confirm full extension before the next station indexes, with the 75 mm window letting you trim the 150 mm throw to the part height.
Compact press-fit of small connectors
About 34 N of usable force at 0.5 MPa is enough to seat PCB headers and small terminals where a full-length cylinder would not fit in the fixture.
Light vertical lift in test rigs
Lifts roughly 2.9 kg vertically with a 2:1 margin, ideal for raising sensor heads or probe plates in benchtop inspection equipment.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X150-75SB with the ACEJ12X150-75SB
If 56.5 N of push at 0.5 MPa is marginal for your jig, step up to bore 16 (100.5 N) or bore 20 (157.1 N) at the same pressure; nothing smaller exists in this family. Note the adjuster is a mechanical end stop for the extend stroke only - it does not hold a load if air is lost. The male rod thread suits I or Y knuckles; FA flange and LB foot mountings bolt to the same face. Order ACEJ12X150 as the current-production replacement and confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X150-75SB
- ✓ 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 ACPJ12X150-75SB 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. The theoretical maximum is 11.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
A stop screw shortens the extend stroke by up to 75 mm inside the ordered 150 mm stroke, giving a 75-150 mm usable range; it cannot lengthen the stroke. The ACPJ family is discontinued - order ACEJ12X150, the current ISO 21287 drop-in in the same bore, stroke and force class, and confirm mounting dimensions before the swap.
