This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X70-40B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X70-40B in place of this model. 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 ACPJ16X70-40B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-40B is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X70-40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-40B
A double acting compact cylinder with an adjustable extend stroke, the ACPJ16X70-40B runs a 16 mm bore over a 70 mm stroke that a stop screw can trim by up to 40 mm, giving a usable 30-70 mm range. 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 20.5 kgf at 1.0 MPa. The hard-anodized aluminium body keeps the mounting length roughly half that of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. Note this model is discontinued; the current drop-in is the ISO 21287 ACEJ16X70.
For sizing, plan on about 60 N of real work at 0.5 MPa rather than the full 100.5 N rating, which is roughly 6 kg of horizontal push or about 5 kg lifted vertically with a 2:1 margin. The male rod thread (B code) suits external knuckles, the M5x0.8 ports depend on the bore, and fixed TPU bumpers decelerate the piston at both ends. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi). No magnet is fitted on this version; order the -S code if you need CMSE / DMSE switch positions.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X70-40B (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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | 106 N |
| Max (@1.0 MPa) | 21 kgf | |
The ACEJ16X70-40B produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-40B Is Used
Small-parts ejection on assembly stations
The 30-70 mm adjustable range lets one cylinder eject plastic housings of varying depths from a nest, with about 60 N of usable push at 0.5 MPa enough for light parts.
Indexing stop on a packaging conveyor
Trimmed via the stop screw to match carton pitch, the 16 mm bore holds a stop pin against 100.5 N at 0.5 MPa; the male rod thread accepts a standard knuckle.
Sample press in a lab fixture
Compact body fits inside a bench-top guard where a full-length profile cylinder will not, delivering 140.7 N at 0.7 MPa for gentle pressing of vials or slides.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-40B with the ACEJ16X70-40B
At 16 mm bore this sits mid-range: the 12 mm bore gives 56.5 N push at 0.5 MPa for lighter clamps, while the 20 mm bore reaches 157.1 N when the load needs more. The 70 mm stroke is within the 75 mm standard for this bore, and the -40 window lets one cylinder serve several stroke points on the same jig. Remember the stop screw only trims the extend stroke; it is not a mid-stroke lock, so the piston drifts if air is lost. FA/FB flanges and LB feet bolt to the ISO 21287 face. Since ACPJ is discontinued, order the ACEJ16X70 and confirm ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X70-40B
- ✓ 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 ACPJ16X70-40B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa, 140.7 N push and 105.6 N pull; theoretical maximum is 20.5 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: a stop screw shortens the 70 mm extend stroke on site, so the working range is 30-70 mm. It shortens only, never lengthens past 70 mm, and the stop is not a load-holding brake.
The ACPJ family is discontinued. The current-production replacement is the ACEJ16X70 (ISO 21287), the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard. This version has no magnet, so no CMSE / DMSE switch can be mounted; the optional -S code adds the magnet for sensing. Mounting: FA/FB flange or LB foot on the standard face, M5x0.8 ports, fixed TPU bumpers at both ends.
