This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X100-10, 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 ACPJ12X100-10
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X100-10 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X100-10 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-10
This is a double acting, adjustable-stroke compact cylinder from AirTAC's discontinued ACPJ line. The 12 mm bore delivers 56.5 N push and 42.4 N pull 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 -10 code adds a 10 mm adjustment window: an external stop screw trims the extend stroke anywhere between 90 and 100 mm on site, so one cylinder covers several fixture positions without changing parts.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters in slim gantries and guarded stations. In practice, plan for about 34 N of usable work at 0.5 MPa (roughly 60% of the rated push), which corresponds to lifting about 3 kg vertically with a 2:1 margin. Note that the 100 mm stroke exceeds the 50 mm standard maximum for bore 12, so it is made to order. This model is discontinued; the current drop-in is ACEJ12X100, and buyers should confirm ISO 21287 mounting dimensions before swapping since the ACP was DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X100-10 (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 ACPJ12X100-10 Is Used
Lab sample pusher
Slides small vials or slides 90-100 mm into a test position; the 10 mm stop window lets technicians fine-travel the extend stroke without swapping cylinders.
Light fixture clamping
The 34 N usable push at 0.5 MPa is enough to seat small PCB brackets or covers in an electronics assembly station.
Compact ejection in tight cells
The short body, about half the length of an ISO 15552 profile cylinder, ejects finished micro-parts from a narrow die or mold pocket.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-10 with the ACEJ12X100-10
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa versus 100.5 N for bore 16 and 157.1 N for bore 20. Choose it for light part presenters and sensor checks; step up a bore if your load needs more than about 34 N of working force. The stop screw only shortens the extend stroke and is not a mid-stroke lock, so the rod will drift if air is lost. The rod end is female M3x0.5 and the port is M5x0.8; FA/FB flange and LB foot mounts bolt to the standard face. No magnet is fitted on this code, so position switches cannot be used unless you order the -S variant. For new projects, specify ACEJ12X100 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X100-10
- ✓ 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 ACPJ12X100-10 FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.2 N and pulls 59.4 N; theoretical maximum is 11.5 kgf at 1.0 MPa. The -10 code gives a 10 mm window: the stop screw trims the 100 mm extend stroke down to 90 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends. The 100 mm stroke is non-standard for bore 12 (50 mm max standard) and is made to order.
Only if the cylinder carries the optional -S magnet code; this version has no magnet, so CMSE or DMSE reed and solid-state switches cannot be mounted. The ACPJ family is discontinued. The current-production replacement is ACEJ12X100 (swap the P for an E), a drop-in in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before ordering since the ACP was DIN-standard.
