This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X110-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X110-20 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 ACPJ20X110-20
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-20 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 ACEJ20X110-20 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-20
Double acting compact cylinder with an adjustable extend stroke, the ACPJ20X110-20 uses a 20 mm bore and a 110 mm made-to-order stroke (above the 100 mm standard maximum for this bore). A stop screw trims the extend stroke anywhere in the 90-110 mm window, so one cylinder can serve several jig positions without changing parts. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa that rises to 219.9 N push and 164.9 N pull, with a theoretical peak of 32 kgf at 1.0 MPa. As a rule of thumb, plan on roughly 94 N of real work at 0.5 MPa, which lifts about 9 kg vertically - halve that for a 2:1 margin and it comfortably handles a 4-5 kg part.
The hard-anodized aluminium body in the ISO 21287 short format saves about 50% of the mounting length of an ISO 15552 profile cylinder, ideal for tight gantries and guarding. A fixed TPU bumper sits at both ends and the S45C hard-chrome rod ends in a female M6x1.0 thread; the port is M5x0.8. Note this model is discontinued: the current drop-in is the ACEJ20X110, so confirm the ISO 21287 mounting dimensions before swapping. No magnet is fitted - the optional -S code is needed for CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X110-20 (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 ACEJ20X110-20 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 ACPJ20X110-20 Is Used
Compact jig clamping
The 90-110 mm trim range lets a fixture builder set the exact clamp position per jig, with 157.1 N push at 0.5 MPa enough for light aluminum brackets.
Small parts ejection
Pushing stamped clips off a die table needs a short, tunable stroke; the stop screw dials the throw down to 90 mm without swapping the cylinder.
Packaging line diverters
A 4-5 kg product pusher on a snack-food conveyor matches the roughly 94 N usable force at 0.5 MPa, and the short body fits under low guarding.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-20 with the ACEJ20X110-20
Size up or down by force: the 16 mm bore gives 100.5 N push at 0.5 MPa, while the 25 mm class in the ACE family steps up from this 20 mm bore's 157.1 N. If your fixture needs position feedback, order the -S variant, since this code has no magnet and accepts no CMSE / DMSE switch. FA/FB flange and LB foot mountings suit the ISO 21287 face. Remember the stop screw only shortens the extend stroke - it is not a mid-stroke lock, and on air loss the rod still drifts. For new builds, specify the ACEJ20X110 instead, as this ACPJ is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X110-20
- ✓ 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 ACPJ20X110-20 FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa, 219.9 N push and 164.9 N pull; theoretical maximum is 32 kgf at 1.0 MPa. The -20 code gives a 20 mm adjustment window, so the 110 mm extend stroke can be trimmed to anywhere between 90 and 110 mm. The 110 mm stroke itself is non-standard (bore 20 standard maximum is 100 mm) and is made to order.
Only with the optional -S magnet code, which enables CMSE / DMSE reed or solid-state switches; this version has no magnet fitted, so no sensor can be mounted. The model is discontinued - the current-production replacement is the ACEJ20X110, a drop-in in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, and check the outline dimensions from the datasheet.
