This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X35-40B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X35-40B 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 ACPJ16X35-40B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X35-40B 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 ACEJ16X35-40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X35-40B
This double acting compact cylinder carries a 16 mm bore and a 35 mm stroke with a 40 mm adjustment window, so an external stop screw trims the extend stroke anywhere in the 0-35 mm range on site. 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 peak of 20.5 kgf at 1.0 MPa. The male rod thread (B code) bolts straight to I/Y knuckles on the ISO 21287 face.
The short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into cramped pick-and-place gantries and test fixtures. As a rule of thumb, plan on about 60 N (roughly 6 kg) of real work at 0.5 MPa, or halve the 10.2 kgf push equivalent for vertical lifts to keep a 2:1 margin. Note this model is discontinued: the current-production drop-in is ACEJ16X35, same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X35-40B (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 ACEJ16X35-40B 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 ACPJ16X35-40B Is Used
Small-parts ejection on assembly fixtures
The 100.5 N push at 0.5 MPa is enough to kick stamped clips or connector housings out of a nest, and the 0-35 mm trimmed stroke keeps the ejector pin travel exactly where the die needs it.
Bench-top leak and press-check stations
With about 60 N of usable work force at 0.5 MPa, the 16 mm bore seats test plugs into small ports on lab rigs, and the M5x0.8 ports suit compact manifold plumbing.
Stroke-trimmed indexing on packaging micro-lines
The 40 mm adjustment window lets a technician shorten the 35 mm extend stroke with the stop screw when a product size changes, without swapping the cylinder.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X35-40B with the ACEJ16X35-40B
Size both ways before ordering: the 12 mm bore gives 56.5 N push at 0.5 MPa if your load is lighter, while the 20 mm bore delivers 157.1 N if you need more thrust. The 35 mm stroke sits well inside the 75 mm max standard stroke for bore 16, so no made-to-order build is needed. The stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. This unit has no magnet fitted (no S code), so no CMSE / DMSE switch can be mounted; order the -S version if sensing is required. Replacement: ACEJ16X35.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X35-40B
- ✓ 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 ACPJ16X35-40B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa push is 140.7 N and pull is 105.6 N; theoretical maximum is 20.5 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: an external stop screw shortens the 35 mm extend stroke, giving a usable range of 0-35 mm. It is a mechanical end stop only - on air loss the piston still drifts, so never rely on it to hold a load. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends.
No - the ACPJ family is discontinued. The current-production replacement is ACEJ16X35 (swap the P for an E), a drop-in in the same bore, stroke and force class; confirm the ISO 21287 mounting dimensions before swapping because the ACP is DIN-standard. This B-code unit has a male rod thread and no magnet, so no CMSE / DMSE switch can be fitted - the magnet is the optional -S code. FA/FB flange and LB foot mounts bolt to the standard ISO 21287 face.
