This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X25-30, 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 ACPJ16X25-30
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X25-30 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X25-30 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-30
The ACPJ16X25-30 is a double acting compact cylinder with an adjustable extend stroke, now discontinued in favour of the ISO 21287 ACEJ16X25. The -30 code gives a 30 mm adjustment window, so a stop screw trims the 25 mm stroke anywhere down to zero on site. Note the adjuster is a mechanical end stop only: on air loss the piston still drifts, so it never holds a load.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits cramped jigs and guarding. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and the rod end is female M4x0.7 with an M5x0.8 air port. This unit has no magnet; order the -S variant if you need CMSE / DMSE switch sensing. Before swapping to the ACEJ16X25, confirm the ISO 21287 mounting dimensions, since the ACP family is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X25-30 (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 ACPJ16X25-30 Is Used
PCB test fixture hold-down
In electronics test racks the short body fits under low fixture lids, and trimming the 25 mm stroke via the stop screw prevents over-compression of spring probes on varying board stacks.
Carton flap tuck on packaging lines
Running at 30-500 mm/s, the 16 mm bore tucks small carton flaps at speed, and the female M4x0.7 rod thread accepts a knuckle for a swing-tuck motion.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-30 with the ACEJ16X25-30
The 30 mm adjustment window covers trim ranges wider than the 25 mm stroke itself, so one unit can serve several fixture variants. Match FA/FB flange or LB foot mounts and I/Y rod knuckles to the ISO 21287 face. If position sensing matters, specify the -S magnet code at order time - it cannot be retrofitted. For new designs, order the current-production ACEJ16X25 instead and verify the mounting footprint against ISO 21287.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X25-30
- ✓ 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 ACPJ16X25-30 FAQ
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, with a theoretical maximum of 20.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
The -30 code is a 30 mm adjustment window: an external stop screw shortens the 25 mm extend stroke on site, so the usable range is 0-25 mm. It is an end stop, not a mid-stroke lock, so the rod can drift on air loss. The ACPJ family is discontinued; the current-production direct is the ACEJ16X25 (same bore, stroke and force class). Confirm the ISO 21287 mounting dimensions before swapping, because the ACP is DIN-standard.
