This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X120-30, 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 ACPJ16X120-30
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X120-30 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 ACEJ16X120-30 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X120-30
Double acting compact cylinder with an adjustable extend stroke, the ACPJ16X120-30 uses a 16 mm bore and a 120 mm stroke that a stop screw trims by up to 30 mm on site, giving a usable range of 90-120 mm. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those rise to 140.7 N and 105.6 N. The 120 mm stroke exceeds the 75 mm standard maximum for bore 16, so it is a made-to-order build. This model is discontinued - the current direct is the ACEJ16X120, so confirm ISO 21287 mounting dimensions before swapping.
The hard-anodized aluminium body is an ISO 21287 short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, which helps in tight jigs and guarding. The rod ends in a female M4x0.7 thread, ports are M5x0.8, fixed TPU bumpers sit at both ends, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). No magnet is fitted; order the -S code if you need CMSE / DMSE switch sensing.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X120-30 (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 ACPJ16X120-30 Is Used
Compact indexing jig
The short ISO 21287 body fits where an ISO 15552 profile cylinder is too long, ejecting machined bushings from a lathe jig within the 90-120 mm window.
Carton kick-off station
A packaging line uses the adjustable stop to knock small cartons off a conveyor at exactly the right travel, running at 30-500 mm/s on filtered air.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X120-30 with the ACEJ16X120-30
The stop screw only shortens the extend stroke; it is not a mid-stroke lock, so the rod can drift if air is lost. FA/FB flange and LB foot mountings bolt to the ISO 21287 face. Since this unit is discontinued, order the ACEJ16X120 as the current-production equivalent.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X120-30
- ✓ 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 ACPJ16X120-30 FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N. The theoretical maximum at 1.0 MPa is 20.5 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
The -30 code gives a 30 mm window: an external stop screw shortens the 120 mm extend stroke to any length down to 90 mm, but it cannot lengthen the stroke and it does not hold a load if air is lost. The ACPJ family is discontinued; the ACEJ16X120 is the current ISO 21287 direct - verify its mounting dimensions before swapping.
