This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X60-20S, 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 ACPJ12X60-20S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X60-20S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 60mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X60-20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-20S
Double acting and adjustable in stroke, the ACPJ12X60-20S is a discontinued DIN-standard compact cylinder with a 12 mm bore and a 60 mm stroke trimmed by a 20 mm stop-screw window, so the extend stroke can be set anywhere from 40 to 60 mm on site. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa that rises to 79.2 N push and 59.4 N pull, with a theoretical ceiling of 11.5 kgf at 1.0 MPa. The 60 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 suits slim jigs and guarded assemblies. Plan on about 34 N of real work at 0.5 MPa (roughly 60% of the rated push), which lifts about 3 kg vertically with a 2:1 margin. The -S code on this model means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted directly. This model is discontinued; the current drop-in is ACEJ12X60, and buyers should confirm ISO 21287 mounting dimensions before swapping since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X60-20S (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 ACPJ12X60-20S Is Used
Small-part ejection on rotary indexing tables
The 56.5 N push at 0.5 MPa is enough to strip finished bushings or caps out of light fixtures, and the 40-60 mm adjustable range lets the operator tune the eject distance per station.
Position-flagged gate on a compact test bench
Because the -S magnet is fitted, CMSE or DMSE switches confirm extend and retract on the 60 mm stroke, giving a verified open/closed signal for leak-test fixtures.
Sample press in a laboratory dispensing rig
About 34 N of usable force at 0.5 MPa presses vials or test coupons under a dispensing nozzle, and the short body fits the tight headroom above a microplate tray.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-20S with the ACEJ12X60-20S
At 56.5 N push (0.5 MPa) this 12 mm bore covers light clamping and part-presenting duties; step up to the 16 mm bore (100.5 N push) if the load is heavier, or down to nothing smaller since 12 mm is the smallest in the family. The 20 mm window gives a 40-60 mm usable extend range via the external stop screw, but the stop is a mechanical end stop only - on air loss the piston still drifts, so it is not a mid-stroke lock. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches. For new projects, order the current-production ACEJ12X60 instead and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X60-20S
- ✓ 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 ACPJ12X60-20S 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. The -20 code sets a 20 mm adjustment window, so a stop screw trims the 60 mm extend stroke down to 40 mm on site. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends. Note the 60 mm stroke is a made-to-order length, since the standard maximum for bore 12 is 50 mm.
This ACPJ is no longer in production. The current drop-in is ACEJ12X60, which swaps the P for an E and matches the same bore, stroke and force class; confirm the ISO 21287 mounting dimensions before swapping, because the ACP is DIN-standard. On this -S version the magnet is fitted, so CMSE / DMSE reed or solid-state switches mount directly for end-of-stroke signals. The body is a hard-anodized aluminium compact cylinder with an S45C hard-chrome rod, M5x0.8 ports and a female M3x0.5 rod thread.
