This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X15-10B, 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 ACPJ12X15-10B
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X15-10B is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 15mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X15-10B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X15-10B
This discontinued AirTAC model is a double acting compact cylinder with an adjustable extend stroke: the -10 code gives a 10 mm stop-screw window, so the 15 mm stroke can be trimmed on site to any usable range between 5 and 15 mm. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa, rising to 79.2 N push at 0.7 MPa, with a theoretical peak of 11.5 kgf at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi), speed runs 30-500 mm/s, and a fixed TPU bumper sits at both ends.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim jigs and fixture plates where a full-length body will not fit. For sizing, treat roughly 34 N (about 60% of the 56.5 N push) as the practical working force at 0.5 MPa, which corresponds to lifting about 1.7 kg vertically - halve that to roughly 0.9 kg if you want a 2:1 margin. The B code gives a male 6 mm rod thread, the port is M5x0.8, and no magnet is fitted unless the -S code is ordered. Note this series is discontinued: the current-production drop-in is ACEJ12X15, so confirm ISO 21287 mounting dimensions before swapping, since the ACP body is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X15-10B (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 ACPJ12X15-10B Is Used
Micro clamp fixture
Trims the extend stroke from 15 mm down to 5 mm to clamp small machined parts in a drill jig, using about 34 N of usable force at 0.5 MPa.
Miniature ejector on an assembly head
The 6 mm male-thread rod (B code) drives a knockout pin that pushes a pressed bushing out of a locating nest in a compact rotary dial table.
Slide gate on a lab dosing unit
Opens a small powder gate in a 30-500 mm/s motion profile; add the -S magnet code if CMSE / DMSE end-position switches are required.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X15-10B with the ACEJ12X15-10B
At 12 mm bore this is the smallest force class in the family: 56.5 N push at 0.5 MPa versus 100.5 N for the 16 mm bore and 157.1 N for the 20 mm bore, so step up if your mechanism needs more than about 34 N of working force. The 15 mm stroke with a 10 mm trim window suits short clamp or eject moves; the stop screw shortens the extend stroke only and is not a mid-stroke lock, so the rod can drift if air is lost. Mounting is FA/FB flange or LB foot, and position sensing needs the optional -S magnet with CMSE / DMSE switches. This model is discontinued - order ACEJ12X15 as the current equivalent and verify the ISO 21287 mounting footprint first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X15-10B
- ✓ 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 ACPJ12X15-10B 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. As a rule of thumb plan on about 34 N of real work (60% of the push rating), which lifts roughly 1.7 kg vertically - or about 0.9 kg with a 2:1 safety margin.
The -10 code adds a stop screw that shortens the 15 mm extend stroke by up to 10 mm, giving a 5-15 mm usable range; it is a mechanical end stop, not a load-holding brake, so the rod can drift on air loss. The ACPJ family is discontinued; ACEJ12X15 is the current ISO 21287 drop-in in the same bore, stroke and force class - confirm its mounting dimensions before swapping, and order the -S version there if you need the optional magnet for CMSE / DMSE switches.
