This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X160-100, 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 ACPJ12X160-100
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X160-100 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 ACEJ12X160-100 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X160-100
The ACPJ12X160-100 is a double acting compact cylinder with an adjustable stroke, now discontinued and replaced by the ACEJ12X160. Its 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 N / 59.4 N at 0.7 MPa), with a theoretical peak of 11.5 kgf at 1.0 MPa. The -100 code sets a 100 mm adjustment window, so a stop screw trims the extend stroke anywhere in a 60-160 mm range on site. Note the 160 mm stroke exceeds the 50 mm standard maximum 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 slots into slim fixtures and guarded assemblies. A fixed TPU bumper sits at both ends, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the female M3x0.5 rod thread with M5x0.8 PT ports keeps plumbing simple. In practice, plan on about 34 N of usable push at 0.5 MPa, which lifts roughly 2.9 kg vertically with a 2:1 margin. Speed runs 30-500 mm/s across 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X160-100 (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 ACPJ12X160-100 Is Used
Lab sample ejector
The 56.5 N push at 0.5 MPa is enough to eject slide trays or microplate racks from a diagnostic analyzer, and the 60-160 mm trim range lets technicians dial the ejection distance without re-plumbing.
Carton kick-off on a small wrapper
A 12 mm bore nudging single cartons off an infeed needs only a few newtons of working force; the short body tucks behind the frame where a full-length cylinder would overhang.
Wire-guide tensioner
With about 2.9 kg of vertical lift capability at a 2:1 margin, the cylinder keeps light spool arms or guide rollers loaded, and the female M3x0.5 thread accepts a small knuckle directly.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X160-100 with the ACEJ12X160-100
At 12 mm bore this is the smallest force step in the family: 56.5 N push at 0.5 MPa versus 100.5 N for bore 16 and 157.1 N for bore 20, so step up if your mechanism needs more than about 34 N of working force. The 160 mm stroke is non-standard for this bore (standard tops out at 50 mm) and is made to order. 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. No magnet is fitted on this version; order the -S code if you need CMSE / DMSE switch positions. For new projects, specify the ACEJ12X160 and confirm ISO 21287 mounting dimensions before the swap.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X160-100
- ✓ 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 ACPJ12X160-100 FAQ
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 maximum of 11.5 kgf at 1.0 MPa. The -100 code gives a 100 mm adjustment window, so the extend stroke can be trimmed anywhere between 60 and 160 mm with the stop screw. The 160 mm stroke itself is made to order, since bore 12 normally tops out at 50 mm standard.
This version ships without a magnet, so no switch can be mounted; the optional -S code adds the magnet that lets CMSE or DMSE reed or solid-state switches read position. The ACPJ family is discontinued - the current-production drop-in is the ACEJ12X160, which matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACPJ follows a DIN-standard footprint.
