This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X100-30, 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 ACPJ12X100-30
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X100-30 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 ACEJ12X100-30 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-30
The ACPJ12X100-30 is a double acting compact cylinder with an adjustable extend stroke: the -30 code gives a 30 mm stop-screw window, so the 100 mm stroke can be trimmed anywhere in a 70-100 mm range on site. Air works on both sides of the 12 mm piston, delivering 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 N / 59.4 N at 0.7 MPa), with a theoretical peak of 11.5 kgf at 1.0 MPa. As a rule of thumb, plan on roughly 33.9 N of real work at 0.5 MPa, which is about 2.9 kg of vertical lift with a 2:1 margin. Note the 100 mm stroke exceeds the 50 mm maximum standard stroke for bore 12, so this unit is made to order.
This model is discontinued; the current-production replacement is the ACEJ12X100, which swaps the P for an E and matches the same bore, stroke and force class in the ISO 21287 family - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard. The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and a fixed TPU bumper sits at both ends. No magnet is fitted on this version (the optional -S code adds one for CMSE / DMSE switches), the rod end is female M3x0.5, the port is M5x0.8, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X100-30 (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 ACPJ12X100-30 Is Used
Small-parts ejection in assembly fixtures
The 70-100 mm trim range lets a fixture builder dial in the exact eject length for connector or PCB push-off stations, with 56.5 N at 0.5 MPa enough for light plastic parts.
Compact slide check in test rigs
Order the -S version when a CMSE or DMSE switch must confirm end positions inside a tight test head; this standard build has no magnet fitted.
Light vertical lift in a packaging head
With about 2.9 kg of practical vertical lift at 0.5 MPa, the 12 mm bore suits lowering a small weigh head or nozzle into a carton, trimmed by the 30 mm stop window.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-30 with the ACEJ12X100-30
Bore 12 is the smallest in this family, so if 56.5 N push at 0.5 MPa is marginal for your jig, step up to bore 16 (100.5 N push / 75.4 N pull at 0.5 MPa) rather than pushing this bore to its limit. The stop screw only shortens the extend stroke within the ordered 30 mm window and is a mechanical end stop, not a mid-stroke lock - the rod still drifts if air is lost, so add a separate clamp if you must hold position. FA/FB flange and LB foot mounts bolt to the ISO 21287 face. For new designs, order the ACEJ12X100 instead, as this ACPJ version is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X100-30
- ✓ 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 ACPJ12X100-30 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 -30 code gives a 30 mm adjustment window, so the 100 mm extend stroke can be shortened to any length from 70 to 100 mm with the stop screw. It is double acting, runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi), and the 100 mm stroke is a made-to-order length because bore 12 normally tops out at 50 mm.
Order the ACEJ12X100, the current-production ISO 21287 successor: swap the P for an E and you get the same 12 mm bore, 100 mm stroke and force class in a matching short body. Check the ISO 21287 mounting dimensions against your fixture before swapping, since the ACPJ was built to the older DIN-standard compact format. Also confirm whether you need the optional -S magnet for CMSE / DMSE switches, and remember the TPU bumper is a fixed end pad, not a load-holding device.
