This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X200-30SB, 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 ACPJ12X200-30SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X200-30SB is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 200mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X200-30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-30SB
This AirTAC ACPJ12X200-30SB is a double acting compact cylinder with an adjustable stroke: a stop screw trims the 200 mm extend stroke by up to 30 mm, giving a usable range of 170-200 mm on site. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 / 59.4 N at 0.7 MPa), with a theoretical peak of 11.5 kgf at 1.0 MPa. The 200 mm stroke exceeds the 50 mm standard limit for bore 12, 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 slots into slim fixtures, slide clamps and instrument gantries. A fixed TPU bumper sits at both ends, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the male rod thread (B code) with the optional -S magnet fitted lets CMSE / DMSE switches report position. As a rule of thumb, plan for about 34 N of real work at 0.5 MPa, which lifts roughly 3 kg vertically with a 2:1 margin. Note: this model is discontinued; the current-production drop-in is ACEJ12X200, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X200-30SB (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 ACPJ12X200-30SB Is Used
Lab sample ejector
The 56.5 N push at 0.5 MPa and 170-200 mm adjustable reach eject sample trays from compact analytical enclosures where a full-length profile cylinder cannot fit.
Micro-assembly gantry stop
Male rod thread plus the fitted -S magnet driving CMSE switches gives position feedback for small-part insertion heads on electronics assembly gantries.
Carton gate actuator
The 200 mm stroke with a 30 mm trim window opens and closes light diverting gates on small carton lines, with the TPU bumper softening each end of travel.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-30SB with the ACEJ12X200-30SB
At 12 mm bore this is the smallest ACPJ size: step up to the 16 mm bore (100.5 N push at 0.5 MPa) if your clamp needs more force, or stay at 12 mm for light locating and eject tasks. The 30 mm window 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. This unit ships with the -S magnet and male rod thread; PT ports, FA/FB flange or LB foot mounting, and 30-500 mm/s speed round out the spec. Order ACEJ12X200 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X200-30SB
- ✓ 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 ACPJ12X200-30SB FAQ
Bore 12 mm, stroke 200 mm (made-to-order, above the 50 mm standard for this bore), 30 mm adjustment window. Push 56.5 N and pull 42.4 N at 0.5 MPa; push 79.2 N and pull 59.4 N at 0.7 MPa; theoretical max 11.5 kgf at 1.0 MPa. Operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, M5x0.8 port, rod 6 mm with male thread, fixed TPU bumpers, -S magnet fitted for CMSE / DMSE switches. Discontinued - replace with ACEJ12X200.
An external stop screw shortens the extend stroke by up to 30 mm, so the rod travels anywhere in the 170-200 mm window; it cannot lengthen travel past the ordered 200 mm and it does not hold a load if air pressure drops. The ACPJ family is discontinued, and the current-production successor is ACEJ12X200 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
