This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X160-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X160-75 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 ACPJ20X160-75
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-75 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 ACEJ20X160-75 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-75
The ACPJ20X160-75 is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 160 mm stroke by up to 75 mm, giving a usable range of 85-160 mm on site. At 0.5 MPa the 20 mm bore delivers 157.1 N push and 117.8 N pull, rising to 219.9 N push at 0.7 MPa. The 160 mm stroke is longer than the 100 mm maximum standard stroke for this bore, so it is a made-to-order build. This model is discontinued; the current-production replacement is the ACEJ20X160.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped packaging heads and test rigs. In practice, plan on roughly 94 N of real work at 0.5 MPa, which lifts about 8 kg vertically with a 2:1 margin. A fixed TPU bumper sits at both ends, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the rod end is female M6x1.0 with M5x0.8 ports. No magnet is fitted on this version, so no CMSE or DMSE switch can be mounted unless the optional -S code was ordered.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-75 (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 ACEJ20X160-75 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 ACPJ20X160-75 Is Used
Packaging head depth setting
The 75 mm window lets one 160 mm cylinder serve carton depths from 85 mm to 160 mm on a wrapping machine without swapping actuators.
Bench-top test press
157.1 N push at 0.5 MPa suits small leak and fit-check fixtures; trim the extend stroke with the stop screw to match each jig.
Compact ejection station
The short body, about 50% shorter than an ISO 15552 profile cylinder, ejects parts from a tight machining fixture where a full-length body will not fit.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-75 with the ACEJ20X160-75
At 157.1 N push at 0.5 MPa this bore sits between the 16 mm (100.5 N) and the 32 mm class above it; step down to 16 mm for lighter clamps or up a bore if 157 N is marginal. Note the 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 lock. FA/FB flange and LB foot mountings bolt to the ISO 21287 face. For a current drop-in, order the ACEJ20X160 and confirm ISO 21287 mounting dimensions before swapping, since the ACP family is DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-75
- ✓ 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 ACPJ20X160-75 FAQ
Push is 157.1 N and pull 117.8 N at 0.5 MPa; at 0.7 MPa push is 219.9 N and pull 164.9 N; theoretical maximum is 32 kgf at 1.0 MPa. The -75 code is a 75 mm adjustment window: a stop screw shortens the 160 mm extend stroke to any length from 85 mm to 160 mm. It is a mechanical end stop, not a mid-stroke lock, so the rod can drift on air loss. The 160 mm stroke is a made-to-order length because the bore 20 standard maximum is 100 mm.
Only if the optional -S magnet was ordered - this version has no magnet, so no CMSE or DMSE switch can be mounted. The ACPJ family is discontinued; the current-production drop-in is the ACEJ20X160 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, because the ACPJ is DIN-standard.
