This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X110-40B, 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 ACPJ12X110-40B
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X110-40B 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 ACEJ12X110-40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-40B
Double acting compact cylinder with an adjustable extend stroke, the ACPJ12X110-40B uses a 12 mm bore and a 110 mm stroke that a stop screw trims by up to 40 mm, giving a usable range of 70-110 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. The 110 mm stroke exceeds the 50 mm standard maximum for bore 12, so this is a made-to-order build. Note this model is discontinued: the current-production replacement is the ACEJ12X110, and buyers should confirm ISO 21287 mounting dimensions before swapping because the ACP series is DIN-standard.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures, test rigs and guarding where a full-length body cannot. A fixed TPU bumper sits at both ends, the hard-anodized aluminium body carries an S45C hard-chrome 6 mm rod with a male thread (the B code), and the port is M5x0.8. No magnet is fitted on this version - the optional -S code is what enables CMSE / DMSE switch sensing. As a rule of thumb, plan on about 34 N of real work at 0.5 MPa, which lifts roughly 2.9 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X110-40B (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 ACPJ12X110-40B Is Used
Lab sample pusher
The 70-110 mm trim range and 56.5 N push at 0.5 MPa suit ejecting sample trays or slides from compact analytical and testing instruments.
Small-part ejection
Light ejection of connectors, pins or stamped parts off an assembly fixture, where the 2.9 kg vertical-lift equivalent covers typical component weights.
Electronics fixture clamp
Low-force clamping of PCBs or small housings in a slim jig, with the short body fitting where an ISO 15552 profile cylinder is too long.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-40B with the ACEJ12X110-40B
At 56.5 N push (0.5 MPa) this bore 12 unit suits light clamping and part-presenting duty; step up to bore 16 (100.5 N push) or bore 20 (157.1 N push) if the load is heavier. Remember the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Mount with FA/FB flange or LB foot hardware on the ISO 21287 face. This model is discontinued; order the ACEJ12X110 as the drop-in successor and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X110-40B
- ✓ 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 ACPJ12X110-40B FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa push is 79.2 N and pull 59.4 N; theoretical maximum is 11.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, port M5x0.8, rod 6 mm male thread. The 110 mm stroke is a made-to-order size above the 50 mm standard maximum for bore 12.
The -40 code gives a 40 mm window: a stop screw shortens the 110 mm extend stroke anywhere down to 70 mm on site. It is a mechanical end stop only - it never holds a load if air is lost. Sensing requires the optional -S magnet code, which allows CMSE / DMSE switches; this B-version has no magnet fitted. The model is discontinued, so spec the ACEJ12X110 as the current replacement.
