This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X60-75S, 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 ACPJ12X60-75S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X60-75S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 60mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X60-75S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-75S
The ACPJ12X60-75S is a double acting compact cylinder with an adjustable extend stroke, built on the DIN-standard ACP short body: hard-anodized aluminium with an S45C hard-chrome rod. At 0.5 MPa the 12 mm bore delivers 56.5 N push and 42.4 N pull; at 0.7 MPa that rises to 79.2 N push. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body cannot. Note that the 60 mm stroke exceeds the 50 mm maximum standard stroke for this bore, so it is a made-to-order item.
The -75 code sets a 75 mm adjustment window: an external stop screw trims the extend stroke on site anywhere within 0-60 mm, and a fixed TPU bumper decelerates the piston at each end. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted for end-position sensing. As a rule of thumb, plan on roughly 34 N (about 3 kg of vertical lift) of usable work at 0.5 MPa rather than the full 56.5 N rating. The ACPJ family is discontinued; the current-production drop-in is the ACEJ12X60, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X60-75S (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 ACPJ12X60-75S Is Used
Small-part ejection from injection molds
The 56.5 N push at 0.5 MPa is enough to kick lightweight molded clips or bushings off a mold face, and the adjustable stop lets the operator dial the eject distance anywhere in the 0-60 mm window without changing hardware.
Position-verified micro press in electronics assembly
With the -S magnet fitted, CMSE or DMSE switches confirm the end positions of a light press or clinch step on PCB fixtures, where the short body must fit inside a compact machine frame.
Clamping of small brackets on a welding fixture
About 34 N of practical holding force at 0.5 MPa secures thin sheet-metal brackets during tack welding, and the LB foot mounting anchors the cylinder flat against the fixture plate.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-75S with the ACEJ12X60-75S
For a 60 mm stroke at this force level, compare both directions: the 16 mm bore gives 100.5 N push at 0.5 MPa if you need more headroom, while stepping down is not possible since 12 mm is the smallest ACPJ bore. The adjuster is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so do not rely on it to hold a load mid-stroke. This model has the -S magnet fitted for CMSE / DMSE switches and a female M3x0.5 rod thread. FA/FB flange and LB foot mountings bolt to the standard face. Since ACPJ is discontinued, order the ACEJ12X60 as the current equivalent and verify ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X60-75S
- ✓ 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 ACPJ12X60-75S 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. It is double acting with a 12 mm bore, 60 mm made-to-order stroke, 75 mm adjustment window, M5x0.8 port, 6 mm rod with female M3x0.5 thread, 0.15-1.0 MPa (22-145 psi) operating pressure and 30-500 mm/s speed.
The -75 code is a 75 mm window: an external stop screw shortens the extend stroke on site to any value from 0 up to the full 60 mm, and a fixed TPU bumper decelerates the piston at both ends. The stop is not a mid-stroke lock, so the rod can still drift if air is lost. The ACPJ family is discontinued - the current-production replacement is the ACEJ12X60, a drop-in in the same bore, stroke and force class; confirm the ISO 21287 mounting dimensions before swapping.
