This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X110-30SB, 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 ACPJ12X110-30SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X110-30SB 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 ACEJ12X110-30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-30SB
The ACPJ12X110-30SB is a discontinued double acting compact cylinder with an adjustable stroke: air drives the piston out and pulls it back, and a stop screw trims the extend stroke anywhere in the 80-110 mm range set by the -30 window. This 12 mm bore unit pushes 56.5 N and pulls 42.4 N at 0.5 MPa, rising to 79.2 N at 0.7 MPa, with a theoretical ceiling of 11.5 kgf at 1.0 MPa. The 110 mm stroke exceeds the 50 mm standard limit for this bore, so it is a made-to-order build.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits cramped pick-and-place heads and slim test fixtures. As a rule of thumb, budget about 34 N of the 56.5 N push for real work at 0.5 MPa, which lifts roughly 2.8 kg vertically with a 2:1 margin. The -S code on this model means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signals. Replacement is the current-production ACEJ12X110; confirm the ISO 21287 mounting dimensions before swapping, since the ACP family was built to a DIN standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X110-30SB (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 ACPJ12X110-30SB Is Used
Micro part ejection from small moulds
The 56.5 N push at 0.5 MPa is enough to strip tiny plastic caps or connector housings off a core pin, and the 80-110 mm adjustable range lets the operator tune the eject position without re-machining the tool.
Sample press in a laboratory test rig
With about 34 N of usable force at 0.5 MPa, the cylinder seats vials or coupon specimens into a fixture gently, while the fitted magnet and a CMSE switch confirm the press stroke is complete before the cycle advances.
Position-flagged slide in a compact vision station
The short body fits inside a slim camera gantry where a full-length profile cylinder cannot, and the -S magnet with a DMSE solid-state switch gives a PLC-ready signal at the trimmed 80-110 mm extend position.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-30SB with the ACEJ12X110-30SB
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa. Step up to the 16 mm bore for 100.5 N or the 20 mm bore for 157.1 N if your part weight or clamp force needs more headroom. Note that the stop screw is a mechanical end stop for the extend stroke only - on air loss the piston can still drift, so never rely on it to hold a load mid-stroke. This model carries the optional -S magnet and a male rod thread (B code), with PT port threads and FA/LB mounting options. The 110 mm stroke is non-standard for this bore and made to order. For new projects, order the ACEJ12X110 instead, which is the current drop-in successor in the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X110-30SB
- ✓ 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 ACPJ12X110-30SB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those rise to 79.2 N and 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The bore is 12 mm with a 6 mm male-thread rod, M5x0.8 ports, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, and a fixed TPU bumper at both ends. The -30 code gives a 30 mm adjustment window, so the extend stroke can be trimmed anywhere between 80 and 110 mm. The 110 mm stroke is a non-standard, made-to-order length for this bore.
An external stop screw mechanically limits the extend stroke, shortening it by up to 30 mm from the full 110 mm; it cannot lengthen the stroke past the ordered value, and it is not a mid-stroke lock - if air is lost the piston can still drift. This ACPJ model is discontinued: the current-production replacement is the ACEJ12X110, made to the ISO 21287 standard in the same bore, stroke and force class. Before swapping, confirm the ISO 21287 mounting dimensions against your fixture, because the ACPJ was built to a DIN-standard compact format.
