This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X160-40S, 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 ACPJ12X160-40S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X160-40S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 160mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X160-40S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X160-40S
This double acting compact cylinder trims its own extend stroke on site: the -40 stop screw shortens the 160 mm stroke by up to 40 mm, giving a usable 120-160 mm range without changing hardware. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa, rising to 79.2 N at 0.7 MPa, with a theoretical ceiling of 11.5 kgf at 1.0 MPa. Note the 160 mm stroke is beyond the 50 mm standard maximum for this bore, 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 slots into slim fixtures and guarded assemblies. Because the -S magnet is fitted, CMSE or DMSE reed and solid-state switches can be clamped straight onto the hard-anodized aluminium body. The fixed TPU bumpers at both ends only soften the ends of travel - they never hold or brake a load, and on air loss the piston drifts. This model is discontinued; the current-production drop-in is ACEJ12X160, so confirm ISO 21287 mounting dimensions before swapping. As a rule of thumb, plan on about 34 N (roughly 3 kg lifted vertically with a 2:1 margin) of real work from the 56.5 N rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X160-40S (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 ACPJ12X160-40S Is Used
Small-part ejection from injection molds
The 120-160 mm adjustable reach clears a molded clip or bushing off the mold face, and the 56.5 N push at 0.5 MPa is ample for parts under about 3 kg lifted vertically with margin.
Position-checked assembly press fixture
With the -S magnet fitted, CMSE or DMSE switches confirm rod position on the 160 mm travel, while the stop screw trims the stroke to 120 mm for shallow pressing of connector pins.
Packaging line product diverter
The compact short body fits between narrow conveyor frames where a full-length profile cylinder will not, pushing lightweight cartons or blisters sideways at 30-500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X160-40S with the ACEJ12X160-40S
At 12 mm bore you are at the light end of the ACPJ range: 56.5 N push at 0.5 MPa versus 100.5 N for the 16 mm bore and 157.1 N for the 20 mm bore. If your jig needs more than about 34 N of usable force, step up to the 16 mm frame. The 6 mm rod carries an M3x0.5 female thread and the ports are M5x0.8, so check your manifold spacing early. FA/FB flange or LB foot mounts bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke sensing. For new designs, order the ACEJ12X160 instead - this ACPJ version is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X160-40S
- ✓ 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 ACPJ12X160-40S FAQ
At 0.5 MPa the 12 mm bore gives 56.5 N push and 42.4 N pull; at 0.7 MPa it gives 79.2 N push and 59.4 N pull, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The -40 code sets a 40 mm adjustment window: a stop screw shortens the 160 mm extend stroke by up to 40 mm, so the working range is 120-160 mm. The 160 mm stroke itself is a made-to-order length, since the standard maximum for this bore is 50 mm.
No - the ACPJ family is discontinued and no longer in production. The current-production replacement is the ACEJ12X160, which swaps the P for an E and matches the same 12 mm bore, 160 mm stroke and force class in the ISO 21287 short-body format. Before swapping, confirm the ISO 21287 mounting dimensions against your existing fixture, since the ACP was built to a DIN-standard footprint. The ACEJ also carries the optional -S magnet code for CMSE / DMSE switches if you need position sensing.
