This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X110-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X110-40 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 ACPJ20X110-40
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-40 is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 110mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X110-40 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-40
This discontinued ACPJ20X110-40 is a double acting compact cylinder with a 40 mm adjustable-stroke window: a stop screw trims the 110 mm extend stroke down to 70 mm on site, so one unit covers a 70-110 mm working range. At 0.5 MPa the 20 mm bore delivers 157.1 N push and 117.8 N pull, rising to 219.9 N at 0.7 MPa. The 110 mm stroke exceeds the 100 mm standard limit for bore 20, so it is a made-to-order stroke. Note that the stop screw is a mechanical end stop only - if air is lost the piston still drifts, so do not rely on it to hold a load.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarded stations. In practice, plan for roughly 94 N of real work at 0.5 MPa (about 0.6 of the push rating), which corresponds to lifting around 9 kg vertically - halve that to about 5 kg if you want a 2:1 margin. This model has no magnet fitted; the optional -S code adds one for CMSE / DMSE switches. For new projects order the current-production ACEJ20X110, a drop-in successor in the same 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 ACEJ20X110-40 (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 (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 ACEJ20X110-40 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 ACPJ20X110-40 Is Used
CNC fixture clamping
The 157.1 N push at 0.5 MPa clamps small aluminium brackets in a milling fixture, and the 70-110 mm adjustable range lets one cylinder serve several part heights.
Packaging line ejection
A 20 mm bore pushing about 9 kg equivalent vertically suits pushing light cartons off a conveyor at 30-500 mm/s, with the TPU bumper softening each end of travel.
Lab sample press
In a compact analytical sample-prep station, the short body fits where a full-length profile cylinder cannot, delivering 219.9 N push at 0.7 MPa for light pressing.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-40 with the ACEJ20X110-40
Size both ways: if 157.1 N push at 0.5 MPa is more than your jig needs, the ACPJ16 at 100.5 N push may suffice; if you need more, step up to the next bore class. Match the 40 mm window to your real stroke spread - the adjuster only shortens the extend stroke, never lengthens it past 110 mm. FA/FB flange or LB foot mounting plus I/Y rod knuckles bolt to the standard face. This model is discontinued; the ACEJ20X110 is the current drop-in replacement - verify ISO 21287 mounting dimensions before ordering.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X110-40
- ✓ 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 ACPJ20X110-40 FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa it pushes 219.9 N and pulls 164.9 N; theoretical maximum is 32 kgf at 1.0 MPa. The -40 code sets a 40 mm adjustment window: a stop screw shortens the 110 mm extend stroke to any value from 70 mm upward. The 110 mm stroke is a made-to-order length because the bore 20 standard maximum is 100 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
This version has no magnet, so no switch can be mounted; order the -S code variant to get the optional magnet for CMSE / DMSE reed or solid-state switches. The ACPJ family is discontinued - the current-production replacement is the ACEJ20X110, a drop-in successor in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, because the ACP is DIN-standard.
