This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X100-100SB, 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 ACPJ12X100-100SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X100-100SB 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 ACEJ12X100-100SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-100SB
Double acting and adjustable in stroke, the ACPJ12X100-100SB is a DIN-standard compact cylinder with a 12 mm bore and a 100 mm stroke trimmed by an external stop screw. The -100 code gives a full 100 mm adjustment window, so the extend stroke can be set anywhere from 0 to 100 mm on site. This unit carries the -S magnet and the B male rod thread, and it pushes 56.5 N and pulls 42.4 N at 0.5 MPa.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight test fixtures and small assembly heads. Plan on roughly 34 N of real work at 0.5 MPa (about 60% of the push rating), which lifts about 3 kg vertically with a 2:1 margin. Note the 100 mm stroke exceeds the 50 mm maximum standard stroke for bore 12, so it is a made-to-order build. This model is discontinued; the current-production replacement is the ACEJ12X100, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X100-100SB (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 ACPJ12X100-100SB Is Used
Lab sample ejector
The 34 N usable push at 0.5 MPa is enough to eject microplate samples or slide trays from a compact analytical station, with the stroke trimmed to the exact tray depth.
Small-part press fit
Light press work such as seating pins into PCB connectors suits the 56.5 N push at 0.5 MPa, and the male rod thread takes an I knuckle for a floating joint.
Gated indexing fixture
With the -S magnet fitted, CMSE or DMSE switches confirm extend and retract positions on a 0-100 mm indexing slide inside a guard where a full-length cylinder will not fit.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-100SB with the ACEJ12X100-100SB
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa. Step up to the 16 mm bore for 100.5 N push or the 20 mm bore for 157.1 N push at the same pressure if your part weight grows. The stop screw is a mechanical end stop for the extend stroke only, not a mid-stroke lock, so the piston can still drift on air loss. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and CMSE or DMSE switches mount because the -S magnet is fitted on this model. Order the ACEJ12X100 as the current drop-in replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X100-100SB
- ✓ 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 ACPJ12X100-100SB 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. The theoretical maximum is 11.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the 100 mm stroke is a made-to-order length above the 50 mm standard maximum for bore 12.
A stop screw shortens the 100 mm extend stroke by up to 100 mm, giving a usable 0-100 mm range; it is an end stop, not a load-holding lock. The ACPJ family is discontinued, and the ACEJ12X100 is the current-production ISO 21287 replacement in the same bore, stroke and force class - confirm the mounting dimensions before swapping.
