This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X120-10, 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 ACPJ16X120-10
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X120-10 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 120mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X120-10 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X120-10
This is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 120 mm stroke by up to 10 mm, giving a usable range of 110-120 mm on site. The 120 mm stroke is beyond the 75 mm standard limit for bore 16, so it is a made-to-order build. Note this model is discontinued; the current-production replacement is ACEJ16X120.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into narrow fixtures and guarding where a full-length body will not fit. A fixed TPU bumper sits at both ends, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the rod end is a female M4x0.7 thread. No magnet is fitted, so no switch can be mounted; order the -S code for CMSE / DMSE sensing.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X120-10 (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 (Ø16mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 75 N |
| 0.7 MPa | 106 N |
| Max (@1.0 MPa) | 15 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 ACPJ16X120-10 Is Used
Indexing stop on a rotary dial table
A 110-120 mm extend range reaches into a compact dial fixture to pin each station, with the TPU bumper softening the approach at both ends of travel.
Carton flap tuck on a packaging line
About 60 N of usable force folds light cardboard flaps at 30-500 mm/s, and the short body fits inside tight guarding where a full-length cylinder cannot.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X120-10 with the ACEJ16X120-10
The stop screw only shortens the extend stroke and is not a mid-stroke lock; on air loss the piston still drifts, so add a separate clamp if holding is critical. FA/FB flange and LB foot mountings bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches. For new designs, order ACEJ16X120 and confirm ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X120-10
- ✓ 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 ACPJ16X120-10 FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa it pushes 140.7 N and pulls 105.6 N; theoretical maximum is 20.5 kgf at 1.0 MPa. The -10 code gives a 10 mm window, so the stop screw trims the 120 mm extend stroke anywhere within 110-120 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s. The 120 mm stroke is made to order, since bore 16 tops out at 75 mm as a standard stroke.
Only if the optional -S magnet is ordered; this version has no magnet, so no CMSE or DMSE switch can be read. The ACPJ family is discontinued, and the current direct is ACEJ16X120 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, because the ACP was built to a DIN-standard footprint.
