This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X40-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X40-10 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 ACPJ16X40-10
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X40-10 is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X40-10 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X40-10
The ACPJ16X40-10 is a double acting compact cylinder with an adjustable extend stroke, now discontinued in favor of the ACEJ16X40. Its 16 mm bore delivers 100.5 N push and 75.4 N pull at 0.5 MPa (140.7 N push at 0.7 MPa), with a theoretical maximum of 20.5 kgf at 1.0 MPa. The -10 code sets a 10 mm adjustment window: an external stop screw trims the 40 mm extend stroke down to 30 mm on site, so one cylinder covers a 30-40 mm range without reordering.
Built on the ISO 21287 short-body format, it saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight jigs and guarding. The hard-anodized aluminium body carries an S45C hard-chrome rod, M5x0.8 ports, a fixed TPU bumper at each end and a female M4x0.7 rod thread. For planning, treat about 60 N (roughly 6 kg) as the usable working force at 0.5 MPa rather than the full 100.5 N rating, and expect about 5 kg of vertical lift capability with a 2:1 margin. Note that the stop screw is a mechanical end stop, not a mid-stroke lock: on air loss the piston still drifts.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X40-10 (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 ACEJ16X40-10 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 ACPJ16X40-10 Is Used
Small-part ejection on assembly benches
The 100.5 N push at 0.5 MPa is enough to kick stamped terminals or molded caps off a nest, and the 30-40 mm trimmed stroke keeps the ejector plate inside a compact tooling plate.
Light clamping of PCB test fixtures
About 60 N of practical working force at 0.5 MPa holds a circuit board against locating pins during in-circuit testing, and the short ISO 21287 body fits under a low fixture lid.
Push-off station on a small conveyor
With roughly 5 kg of vertical-lift equivalent and a 30-40 mm adjustable extend range, the cylinder parts or diverts lightweight cartons on a benchtop transfer line.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X40-10 with the ACEJ16X40-10
Size between bores: an ACPJ12 gives 56.5 N push at 0.5 MPa, while stepping up to an ACPJ20 raises it to 157.1 N, so the 16 mm bore at 100.5 N sits mid-range for light clamping and indexing. Match FA/FB flange or LB foot mounting to the fixture, and if position sensing is needed, order the -S variant with the optional magnet so CMSE / DMSE switches can be fitted; this version has no magnet. Remember the adjuster shortens the extend stroke only and does not hold a load against air loss. Since this model is discontinued, confirm ISO 21287 mounting dimensions and switch to the current-production ACEJ16X40.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X40-10
- ✓ 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 ACPJ16X40-10 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), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, and the port is M5x0.8. The -10 code gives a 10 mm window that trims the 40 mm extend stroke to as little as 30 mm.
The short ISO 21287-style body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange or LB foot mounting and a female M4x0.7 rod thread. A fixed TPU bumper at each end absorbs end-of-travel impact only; it never locks or holds a load. This model is discontinued: the current drop-in is the ACEJ16X40 (same bore, stroke and force class), so confirm the ISO 21287 mounting dimensions before swapping.
