This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X35-10SB, 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 ACPJ12X35-10SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X35-10SB is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X35-10SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X35-10SB
Double acting and adjustable in stroke, the ACPJ12X35-10SB is a DIN-standard compact cylinder with a 12 mm bore and a 35 mm stroke that a stop screw trims by up to 10 mm, giving a usable extend range of 25-35 mm. Push force is 56.5 N and pull 42.4 N at 0.5 MPa, rising to 79.2 N at 0.7 MPa, with a theoretical peak of 11.5 kgf at 1.0 MPa. The male rod thread (B code) and the fitted -S magnet for CMSE / DMSE switches make it easy to drop into small fixtures with position sensing. Note that this model is discontinued; the current-production replacement is ACEJ12X35.
The hard-anodized aluminium body is an ISO 21287-class short build, cutting roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it suits cramped jigs and guarding. A rule of thumb: plan on about 34 N of usable push at 0.5 MPa (roughly 60% of rating), which lifts about 2.9 kg vertically with a 2:1 margin. A fixed TPU bumper sits at both ends, speed spans 30-500 mm/s, and the port is M5x0.8. Confirm ISO 21287 mounting dimensions before swapping to the ACEJ.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X35-10SB (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 ACPJ12X35-10SB Is Used
Micro assembly press
A 12 mm bore pushing 56.5 N at 0.5 MPa seats small connectors or bearings in electronics fixtures, with the stop screw trimming the extend stroke between 25 and 35 mm to match part height.
Position-verified ejection
With the fitted -S magnet, CMSE or DMSE switches confirm rod position on a compact ejector that pushes rejected vials off a pharmaceutical line within a 35 mm stroke.
Short-stroke divert gate
The short body, about 50% shorter in mounting length than an ISO 15552 profile cylinder, fits beside a narrow conveyor to swing a lightweight gate, lifting about 2.9 kg vertically with margin.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X35-10SB with the ACEJ12X35-10SB
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, step up to the 16 mm bore (100.5 N push at 0.5 MPa) or the 20 mm bore (157.1 N). For lighter pick-and-place under about 34 N of working force, stay here. The stop screw only shortens the extend stroke within the 10 mm window and is not a mid-stroke lock, so the rod can drift if air is lost. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and the -S magnet this model carries accepts CMSE / DMSE switches. Order ACEJ12X35 as the current drop-in successor.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X35-10SB
- ✓ 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 ACPJ12X35-10SB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa push is 79.2 N and pull 59.4 N; theoretical maximum is 11.5 kgf at 1.0 MPa. The 12 mm bore has an M5x0.8 port, a 6 mm rod with male thread, and the -10 code gives a 10 mm adjustment window (25-35 mm usable extend stroke). 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.
No, the ACPJ12X35-10SB is discontinued. The current-production replacement is ACEJ12X35, an ISO 21287 compact cylinder in the same bore, stroke and force class. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. The fixed TPU bumpers at both ends simply decelerate the rod at each end of travel.
