This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X200-20SB, 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 ACPJ12X200-20SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X200-20SB 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 ACEJ12X200-20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-20SB
This ACPJ12X200-20SB is a double acting compact cylinder with an adjustable extend stroke: the -20 stop screw trims the 200 mm stroke by up to 20 mm on site, giving a usable range of 180-200 mm. 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), which is roughly 34 N of practical working force at 0.5 MPa - enough to lift about 2.9 kg vertically with a 2:1 margin. The 200 mm stroke exceeds the 50 mm standard maximum for this bore, so it is a non-standard, made-to-order build. A magnet is fitted under the -S code, so CMSE / DMSE reed or solid-state switches can be mounted directly.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it a fit for slim gantries and guarded stations. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with a hard-anodized aluminium body, S45C hard-chrome rod, male rod thread (B code) and fixed TPU bumpers at both ends. Note: this model is discontinued - the current-production replacement is ACEJ12X200, so confirm ISO 21287 mounting dimensions before swapping from the DIN-standard ACP footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X200-20SB (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 ACPJ12X200-20SB Is Used
Position-verified ejection on SMT lines
The fitted magnet lets a CMSE switch confirm the trimmed 180-200 mm extend stroke before the PCB magazine indexer advances, at 30-500 mm/s cycle speeds.
Light clamping in slim fixture plates
About 34 N of practical 0.5 MPa force suits spring-loaded lids on electronics test jigs where the short body must fit inside a 60 mm guard channel.
Sample pusher in lab analysers
The male rod thread drives a small sample tray between reagent stations, lifting roughly 2.9 kg vertically with margin, inside a compact analyser frame.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X200-20SB with the ACEJ12X200-20SB
Size up or down by force: the 16 mm bore gives 100.5 N push at 0.5 MPa if 56.5 N is marginal, while stepping below 12 mm is not offered in this family. The adjuster is a mechanical end stop for the extend stroke only - it does not lock the piston, so on air loss the rod still drifts and an external brake is needed for load holding. Match FA/FB flange or LB foot mounts and I/Y rod knuckles to the ISO 21287 face, and remember the magnet is the optional -S code (fitted here) for CMSE / DMSE switches. For new designs, order the ACEJ12X200 instead, as this ACPJ is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X200-20SB
- ✓ 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 ACPJ12X200-20SB 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. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and speed is 30-500 mm/s. The 200 mm stroke is a made-to-order length since the bore 12 standard maximum is 50 mm.
The -20 code gives a 20 mm window: an external stop screw shortens the extend stroke anywhere within 180-200 mm; it cannot lengthen the stroke past 200 mm. The stop is not a load-holding device. This ACPJ is discontinued - the drop-in successor is ACEJ12X200 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before converting from the DIN-standard ACP footprint.
