This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X60-40SB, 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 ACPJ12X60-40SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X60-40SB 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 ACEJ12X60-40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-40SB
A double acting, adjustable-stroke compact cylinder for tight machine frames, the ACPJ12X60-40SB uses a 12 mm bore to deliver 56.5 N of push and 42.4 N of pull at 0.5 MPa (79.2 N / 59.4 N at 0.7 MPa). The -40 code means a stop screw trims the 60 mm extend stroke by up to 40 mm on site, giving a usable 20-60 mm range. The 60 mm stroke is above the 50 mm standard maximum for bore 12, so it is a made-to-order length. Note: this ACPJ model is discontinued; the current-production replacement is ACEJ12X60.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim jigs and guarding where a full-length body cannot. Because the S code is ordered, the magnet is fitted and CMSE / DMSE reed or solid-state switches can be clamped straight on for end-of-stroke sensing. A practical sizing check: at 0.5 MPa plan on roughly 34 N (about 3.4 kgf) of real work, and expect it to lift about 2.9 kg vertically with a 2:1 margin. The male (B) rod thread carries an M3x0.5 external thread, and a fixed TPU bumper sits at both ends.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X60-40SB (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 ACPJ12X60-40SB Is Used
Semiconductor test fixture clamping
The 20-60 mm trim range lets a technician dial in the exact clamp position on a wafer carrier jig, with 56.5 N of push at 0.5 MPa enough for light plastic or thin aluminium parts.
Small-parts ejection on packaging lines
With the fitted magnet and a CMSE switch, the PLC confirms each 60 mm eject cycle on a blister or carton line, running at speeds from 30 to 500 mm/s.
PCB push-off in electronics assembly
The short body, about 50% shorter than an ISO 15552 profile cylinder, fits inside a compact SMT unload station where a 42.4 N pull force gently parts boards from a conveyor stop.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X60-40SB with the ACEJ12X60-40SB
At 12 mm bore this is the lightest force class: 56.5 N push at 0.5 MPa. If your load needs more, step up to bore 16 (100.5 N push at 0.5 MPa) or bore 20 (157.1 N). For lighter pick-and-place under about 34 N of working force, this size keeps air consumption low. The stop screw only shortens the extend stroke and is not a mid-stroke lock - on air loss the piston can still drift, so do not rely on it to hold a load. FA flange or LB foot mounts bolt to the standard face, and the -S magnet on this unit accepts CMSE / DMSE switches. Before ordering, confirm ISO 21287 mounting dimensions for the ACEJ12X60 replacement, since the ACP series is DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X60-40SB
- ✓ 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 ACPJ12X60-40SB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those rise to 79.2 N and 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. It is double acting with a 12 mm bore, 6 mm rod, M5x0.8 ports, a 40 mm adjustment window over the 60 mm stroke, 0.15-1.0 MPa (22-145 psi) operating pressure and 30-500 mm/s speed. The 60 mm stroke is a made-to-order length above the 50 mm standard maximum for this bore.
No - the ACPJ family is discontinued. The current drop-in is ACEJ12X60, the same bore, stroke and force class, but confirm the ISO 21287 mounting dimensions before swapping because the ACP is DIN-standard. On this unit the -S magnet is fitted, so CMSE / DMSE switches can be mounted for position feedback. A stop screw on the extend side shortens the stroke anywhere within the 40 mm window (usable 20-60 mm); it is a mechanical end stop, not a load-holding brake, and the fixed TPU bumpers at each end simply soften the stops.
