This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X110-40SB, 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 ACPJ12X110-40SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X110-40SB is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 110mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X110-40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-40SB
A discontinued double acting compact cylinder with an adjustable extend stroke, the ACPJ12X110-40SB runs on a 12 mm bore and delivers 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 N push at 0.7 MPa). The -40 code gives a 40 mm adjustment window, so a stop screw trims the extend stroke anywhere in a 70-110 mm range on site. The 110 mm stroke is beyond the 50 mm maximum standard stroke for this bore, so it is a made-to-order build. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted directly on the body.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits cramped jigs and guarding where a full-length body cannot fit. A hard-anodized aluminium body carries an S45C hard-chrome 6 mm rod with a male thread (B code), and fixed TPU bumpers sit at both ends. For sizing, expect roughly 34 N of usable push at 0.5 MPa, which lifts about 2.9 kg vertically with a 2:1 margin. Production has ended: the current drop-in is the ACEJ12X110, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X110-40SB (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 ACPJ12X110-40SB Is Used
Small-part ejection from fixtures
The 56.5 N push at 0.5 MPa is enough to kick machined pins or stamped clips off a jig, and the 70-110 mm adjustable range lets one cylinder serve several fixture variants.
Position-verified test stations
With the fitted magnet and CMSE / DMSE switches, a bench-top leak or assembly check can confirm the rod reached the trimmed end position before the cycle advances.
Light clamping in tight enclosures
The short body, about 50% shorter than an ISO 15552 profile cylinder, fits inside compact guarding for pressing connectors or labels with roughly 34 N of working force.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-40SB with the ACEJ12X110-40SB
At 12 mm bore this is the smallest force class in the family: 56.5 N push at 0.5 MPa. If your load needs more, the 16 mm bore gives 100.5 N push and the 20 mm bore 157.1 N at the same pressure. Remember the stop screw only trims the extend stroke within the 40 mm window; it is not a mid-stroke lock, so the rod still drifts if air is lost. The male rod thread (B) pairs with I/Y knuckles, and FA flange or LB foot mounts bolt to the face. If you need position feedback, this S-coded unit already carries the magnet for CMSE / DMSE switches. For new projects, order the current ACEJ12X110 instead and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X110-40SB
- ✓ 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 ACPJ12X110-40SB 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 40 mm adjustment window (usable extend stroke 70-110 mm), M5x0.8 ports, 6 mm male-thread rod, operating pressure 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s and fixed TPU bumpers. The 110 mm stroke is a made-to-order length above the 50 mm standard maximum for this bore.
This model is no longer in production. The current drop-in is the ACEJ12X110, which matches the same 12 mm bore, 110 mm stroke and force class in the ISO 21287 family. Because the ACPJ was built to a DIN-standard footprint, confirm the ISO 21287 mounting dimensions before swapping. The ACEJ also accepts the same FA/LB mounts and, with the -S code, CMSE / DMSE switches.
