This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X110-10B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X110-10B 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 ACPJ20X110-10B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-10B 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 ACEJ20X110-10B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-10B
This is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 110 mm stroke by up to 10 mm on site, giving a usable range of 100-110 mm. 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, with a theoretical peak of 32 kgf at 1.0 MPa. The 110 mm stroke exceeds the 100 mm maximum standard stroke for bore 20, so this unit is made to order. Note that the ACPJ family is discontinued; ACEJ20X110 is the current-production replacement in the same bore, stroke and force class.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into shallow fixtures, sliding guards and compact gantries. In practice, plan for roughly 94 N of usable push at 0.5 MPa, which lifts about 8 kg vertically with a 2:1 margin - enough for small clamping plates or lightweight parts. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and the rod ends in a male thread (B code). Speed range is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X110-10B (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 ACEJ20X110-10B 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 ACPJ20X110-10B Is Used
Compact press fixture
The 157.1 N push at 0.5 MPa suits light staking and snap-fit pressing on small electronics assemblies, with the 10 mm trim letting the operator dial the 110 mm stroke down to 100 mm for part-height changes.
Pick-and-place lift head
With about 8 kg of vertical lift capacity at a 2:1 margin, the cylinder raises lightweight plastic trays or PCB carriers on a compact gantry where a full-length profile cylinder would not fit.
Sliding guard interlock
The short body, roughly 50% shorter than an ISO 15552 profile cylinder, drives machine-guard doors and sliding covers on packaging machines within tight frame depth.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-10B with the ACEJ20X110-10B
Size against the load: bore 16 gives 100.5 N push at 0.5 MPa, while this 20 mm bore reaches 157.1 N push and 117.8 N pull - and 20 mm is the largest bore in the ACPJ range, so anything heavier means stepping up to the ACE family in 25 mm (confirm force from datasheet). The stop screw only shortens the extend stroke; it is not a mid-stroke lock, so on air loss the piston still drifts and an external brake is needed to hold a load. Mounting options are FA/FB flange and LB foot. This model has no magnet (no S code), so CMSE or DMSE switches cannot be fitted - order the -S variant if sensing is required. For new projects, specify ACEJ20X110 and confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X110-10B
- ✓ 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 ACPJ20X110-10B 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. Bore is 20 mm, stroke 110 mm with a 10 mm adjustment window (usable 100-110 mm), rod 10 mm with a male thread, port M5x0.8, speed 30-500 mm/s, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C. The 110 mm stroke is a made-to-order length above the 100 mm standard maximum for bore 20.
An external stop screw shortens the extend stroke by up to 10 mm within the ordered window; it cannot lengthen the stroke past 110 mm and it does not lock or hold a load on air loss. The ACPJ family is no longer in production - ACEJ20X110 is the current drop-in successor with the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, because the ACP was built to a DIN-standard footprint. FA/FB flange and LB foot mounts bolt straight on, and the optional -S magnet code enables CMSE / DMSE switches.
