This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X35-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X35-40 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 ACPJ16X35-40
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X35-40 is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X35-40 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X35-40
A double acting compact cylinder with an adjustable stroke, the ACPJ16X35-40 uses a 16 mm bore to deliver 100.5 N of push force and 75.4 N of pull force at 0.5 MPa, rising to 140.7 N at 0.7 MPa. An external stop screw trims the 35 mm extend stroke anywhere within the ordered 40 mm window, so one cylinder covers a 0-35 mm working range without swapping parts. The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding where a full-length body will not fit.
For sizing, plan on about 60 N of usable push at 0.5 MPa and expect roughly 5 kg of vertical lift capability with a 2:1 margin. The fixed TPU bumper at each end decelerates the piston at the ends of travel only - it never locks or holds a load, so on air loss the rod will drift. Note that this model is discontinued: the current-production drop-in is the ACEJ16X35, which matches the same bore, stroke and force class, but confirm the ISO 21287 mounting dimensions before swapping because the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X35-40 (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 ACEJ16X35-40 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 ACPJ16X35-40 Is Used
Small-part ejection from plastic molds
The 100.5 N push at 0.5 MPa is enough to kick lightweight molded caps or bushings off a mold face, and the 0-35 mm adjustable range lets the setter tune the eject travel without changing cylinders.
Clamping fixtures on electronics assembly benches
About 60 N of usable clamp force holds PCB carrier trays against a locating stop, and the short body fits inside the shallow fixture plates typical of SMT support tooling.
Sorting gates on small-parts conveyors
The rod swings a lightweight diverter flap to route components between chutes; with the -S magnet code, CMSE or DMSE switches confirm gate position at each end of the trimmed stroke.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X35-40 with the ACEJ16X35-40
At 16 mm bore this sits in the light-duty band: the 12 mm bore gives 56.5 N push at 0.5 MPa while the 20 mm bore reaches 157.1 N, so step up if your part weight or friction load exceeds about 60 N of real work. The 35 mm stroke is well inside the 75 mm maximum standard stroke for this bore. The female M4x0.7 rod thread accepts standard I/Y knuckles, and FA flange or LB foot mounts bolt to the ISO 21287 face. If you need position sensing, order the -S variant with the optional magnet for CMSE / DMSE switches - this code has no magnet fitted. For new builds, specify the ACEJ16X35 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X35-40
- ✓ 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 ACPJ16X35-40 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. The theoretical maximum is 20.5 kgf at 1.0 MPa. In practice, budget about 60 N for real work at 0.5 MPa, which corresponds to lifting roughly 5 kg vertically with a 2:1 safety margin. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
The -40 code is a 40 mm adjustment window: an external stop screw shortens the 35 mm extend stroke on site, giving any usable stroke from 0 to 35 mm. It is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. This model is discontinued; the current-production replacement is the ACEJ16X35, a drop-in in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to the DIN standard.
