This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X160-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X160-40S 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 ACPJ20X160-40S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40S is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 160mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X160-40S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40S
Double acting and adjustable, the ACPJ20X160-40S is a discontinued DIN-standard compact cylinder: a 20 mm bore pushing 157.1 N (pull 117.8 N) at 0.5 MPa, with a stop screw that trims the extend stroke anywhere inside the 40 mm window, so the working range is 120-160 mm. The 160 mm stroke is longer than the 100 mm standard limit for bore 20, so this unit is made to order. The -S code means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clamped straight onto the hard-anodized aluminium body.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters inside tight jigs and guarding. For sizing, treat about 94 N (roughly 9.6 kgf) as the realistic working thrust at 0.5 MPa, and expect about 8 kg of vertical lift capability once a 2:1 margin is applied. This model is discontinued; the current-production drop-in is ACEJ20X160 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-40S (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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 kgf | |
The ACEJ20X160-40S 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 ACPJ20X160-40S Is Used
Fixture clamping on CNC pallets
The 157.1 N push at 0.5 MPa clamps aluminium housings in machining fixtures, with the 40 mm window letting one cylinder serve different part heights between 120 and 160 mm.
Position-verified ejector on a packaging line
With the -S magnet fitted, CMSE or DMSE switches confirm the rod has reached the trimmed extend position before the carton closer cycles, at speeds up to 500 mm/s.
Press-fit of small bushings
About 94 N of practical working force at 0.5 MPa suits light press-in jobs such as bushings into plastic brackets, with the TPU bumper softening both stroke ends.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-40S with the ACEJ20X160-40S
At 20 mm bore this sits mid-range in the ACPJ family: the 16 mm bore delivers 100.5 N push at 0.5 MPa, while the 25 mm class steps up beyond this model's 157.1 N, so check part weight before committing. The 40 mm adjuster is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so it is not a load-holding brake. FA/FB flange and LB foot mountings bolt to the standard face, and because the -S magnet is fitted, CMSE / DMSE switches work without reordering. Order the ACEJ20X160 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-40S
- ✓ 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 ACPJ20X160-40S FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those rise to 219.9 N and 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The -40 code gives a 40 mm adjustment window, so the extend stroke can be trimmed anywhere in the 120-160 mm range. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8. Note the 160 mm stroke exceeds the 100 mm standard limit for bore 20, so it is made to order.
An external stop screw shortens the extend stroke on site within the ordered 40 mm window; it never lengthens the stroke past 160 mm, and it is a mechanical end stop rather than a mid-stroke lock, so the rod still drifts if air is lost. The ACPJ family is discontinued - the current-production drop-in is ACEJ20X160, the same bore, stroke and force class in the ISO 21287 ACE series. Confirm the ISO 21287 mounting dimensions before swapping, because the ACP is DIN-standard. This unit carries the optional -S magnet, so CMSE / DMSE switches can be mounted.
