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

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-20S
This AirTAC cylinder is double acting with an adjustable extend stroke: a stop screw trims the 110 mm stroke by up to 20 mm, giving a usable range of 90-110 mm on site. The 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa, rising to 219.9 N push at 0.7 MPa. The 110 mm stroke exceeds the 100 mm standard limit for this bore, so it is a made-to-order length. Note: this model is discontinued; the current-production replacement is the ACEJ20X110, so confirm ISO 21287 mounting dimensions before swapping.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into cramped fixture plates and guarding frames. The hard-anodized aluminium body carries a fixed TPU bumper at each end, and the S45C hard-chrome rod ends in a female M6x1.0 thread. Because the -S code is on this unit, the magnet is fitted and CMSE / DMSE reed or solid-state switches can be clamped on. A practical sizing rule: at 0.5 MPa plan on roughly 94 N of real work (about 0.6 of the push force), which lifts about 9 kg vertically - halve that for a 2:1 margin and match it to your part weight.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X110-20S (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 ACEJ20X110-20S 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 ACPJ20X110-20S Is Used
Fixture clamping on CNC pallets
The 90-110 mm trim range lets a machinist set exact clamp travel per pallet; 157.1 N push at 0.5 MPa suits light aluminum workholding.
Position-verified ejector on an assembly line
With the fitted -S magnet, CMSE switches confirm full extend or retract, so a PLC can gate the next station on the 110 mm stroke.
Carton push-off in a tight packaging head
The short body, about 50% shorter than an ISO 15552 profile cylinder, fits inside the guard where a full-length body cannot, pushing cartons with about 94 N of usable force.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-20S with the ACEJ20X110-20S
Size both ways before committing: the 16 mm bore gives 100.5 N push at 0.5 MPa if your load is lighter, while the 25 mm class in the ACE range steps up when you need more than the 157.1 N this bore produces. Remember the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches. Order the ACEJ20X110 as the current drop-in and verify mounting dimensions against the ISO 21287 datasheet.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X110-20S
- ✓ 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 ACPJ20X110-20S 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 -20 code gives a 20 mm adjustment window, so the 110 mm extend stroke can be trimmed to anywhere in a 90-110 mm range. It runs on air filtered to 40 um at 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. The 110 mm stroke is a made-to-order length above the 100 mm standard for this bore.
Yes - the S in the code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke signals. The ACPJ family is discontinued; the current-production drop-in is the ACEJ20X110 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint.
