This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X60-75SB, 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 ACPJ12X60-75SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X60-75SB 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 ACEJ12X60-75SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-75SB
The ACPJ12X60-75SB is a discontinued double acting compact cylinder with an adjustable extend stroke: an external stop screw trims the 60 mm stroke on site within the ordered 75 mm window, giving a usable range of 0-60 mm. Air drives the rod in both directions, a fixed TPU bumper decelerates at each end, and the hard-anodized aluminium body with an S45C hard-chrome rod runs at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s. The 60 mm stroke exceeds the 50 mm standard maximum for bore 12, so this unit is a made-to-order build.
At 0.5 MPa the 12 mm bore delivers 56.5 N push and 42.4 N pull (79.2 N / 59.4 N at 0.7 MPa, 11.5 kgf theoretical max). Plan on roughly 34 N of real work - about 3 kg lifted vertically with a 2:1 margin - rather than the full rating. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and the fitted -S magnet accepts CMSE / DMSE switches. For new projects order the current ACEJ12X60, confirming ISO 21287 mounting dimensions first.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X60-75SB (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 ACPJ12X60-75SB Is Used
Small-part ejection from plastic molds
The 56.5 N push at 0.5 MPa and trimmed extend stroke let a mold shop eject light nylon or POM parts from a tight die pocket, with the 0-60 mm range set on site by the stop screw.
Position-verified fixture clamping
With the fitted -S magnet driving CMSE or DMSE switches, an electronics assembly line confirms clamp-and-return on PCB test fixtures using the 42.4 N pull stroke.
Compact press for connector pins
The short body, about 50% shorter in mounting length than an ISO 15552 profile cylinder, fits inside a cable-assembly jig where the 79.2 N push at 0.7 MPa seats small connector pins.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-75SB with the ACEJ12X60-75SB
Size up or down from this 12 mm bore by force: the 16 mm bore gives 100.5 N push at 0.5 MPa and the 20 mm bore 157.1 N, while this unit's 56.5 N push / 42.4 N pull suits light clamping and positioning. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve for suspended loads. The male rod thread (B code) and PT ports suit direct knuckle mounting, and the fitted -S magnet enables CMSE / DMSE switch feedback. This model is discontinued; the ACEJ12X60 is the current-production drop-in in the same bore, stroke and force class - verify ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X60-75SB
- ✓ 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 ACPJ12X60-75SB FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa push rises to 79.2 N and pull to 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. It is double acting with a 75 mm adjustment window on the 60 mm stroke, M5x0.8 ports, a 6 mm male-thread rod, speed 30-500 mm/s, fixed TPU bumpers at both ends, and a fitted -S magnet for CMSE / DMSE switches. The 60 mm stroke is a made-to-order length above the 50 mm standard maximum for bore 12.
AirTAC no longer produces the ACPJ family. The current drop-in is the ACEJ12X60 - swap the P for an E - which matches the same 12 mm bore, 60 mm stroke and force class in the ISO 21287 short-body format. Because the ACPJ was built to a DIN-standard compact layout, confirm the ISO 21287 mounting dimensions and FA/LB mounting interfaces against your fixture before ordering the replacement.
