This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X25-30SB, 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 ACPJ16X25-30SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X25-30SB 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 ACEJ16X25-30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-30SB
This ACPJ16X25-30SB is a double acting, adjustable-stroke compact cylinder, now discontinued and superseded by the ACEJ16X25 in the ISO 21287 family. The 16 mm bore delivers 100.5 N push and 75.4 N pull at 0.5 MPa, rising to 140.7 N at 0.7 MPa, with a theoretical ceiling of 20.5 kgf at 1.0 MPa. The -30 code gives a 30 mm adjustment window, so an external stop screw trims the 25 mm extend stroke anywhere between 0 and 25 mm on site. The S in the code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be added for end-position sensing.
Practically, plan on roughly 60 N of usable work at 0.5 MPa (about 0.6 of the rated push), which is enough to lift about 6 kg vertically with a 2:1 margin. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body cannot. A hard-anodized aluminium body, S45C hard-chrome rod, fixed TPU bumpers at both ends and a male (B) rod thread round out the build. Before swapping in the ACEJ16X25, confirm the ISO 21287 mounting dimensions, since the ACP was built to a DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X25-30SB (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 ACPJ16X25-30SB Is Used
Small-parts ejection on assembly stations
The 100.5 N push at 0.5 MPa clears finished 5-6 kg components from a nest, while the 0-25 mm trimmed stroke keeps the ejector pin travel exactly where the fixture needs it.
Light clamping of machined housings
With about 60 N of usable clamping force at 0.5 MPa, the male-thread rod drives a small clamp arm on aluminium die-cast parts in a CNC secondary-operation jig.
Position-verified indexing in compact gantries
The fitted -S magnet accepts CMSE / DMSE switches, so the controller confirms extend and retract inside guard panels where the short body is the only thing that fits.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-30SB with the ACEJ16X25-30SB
Size both ways: the 12 mm bore gives 56.5 N push at 0.5 MPa, while the 20 mm bore reaches 157.1 N, so this 16 mm unit at 100.5 N sits in the middle for light clamping and indexing. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so do not rely on it to hold a load. FA/FB flange and LB foot mountings bolt to the standard ISO 21287 face, and the fitted -S magnet pairs with CMSE / DMSE switches. For new designs, order the current-production ACEJ16X25 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X25-30SB
- ✓ 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 ACPJ16X25-30SB FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa that rises to 140.7 N push and 105.6 N pull, with a theoretical maximum of 20.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, fluid air filtered to 40 um, and the port is M5x0.8. The rod is 8 mm with a male thread (B code).
The -30 code sets a 30 mm adjustment window: an external stop screw shortens the 25 mm extend stroke anywhere from 0 to 25 mm, with fixed TPU bumpers decelerating at both ends. The stop is not a load-holding brake. This ACPJ is discontinued; the current drop-in is the ACEJ16X25 (swap the P for an E) in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, as the ACP was DIN-standard.
