This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X150-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X150-40S 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 ACPJ20X150-40S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-40S is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X150-40S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-40S
The ACPJ20X150-40S is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 150 mm stroke by up to 40 mm, giving a usable range of 110-150 mm on site. This bore 20 size delivers 157.1 N push and 117.8 N pull at 0.5 MPa, rising to 219.9 N at 0.7 MPa, with a theoretical peak of 32 kgf at 1.0 MPa. The 150 mm stroke exceeds the 100 mm standard maximum for bore 20, so it is a made-to-order build. Note this ACPJ model is discontinued; the current-production successor is the ACEJ20X150.
Its hard-anodized aluminium body is an ISO 21287 short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into deep guards and narrow gantry rails. The -S magnet this model carries lets you bolt on CMSE or DMSE reed or solid-state switches for end-of-stroke signalling. As a rule of thumb, plan on roughly 94 N (about 9.6 kg) of real work at 0.5 MPa, or lift about 8 kg vertically with a 2:1 margin. Fixed TPU bumpers sit at both ends, and speed runs 30-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X150-40S (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 ACEJ20X150-40S 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 ACPJ20X150-40S Is Used
Bench-top press jig
Rivet or pin staking on small aluminium brackets: 157.1 N push at 0.5 MPa suits light forming, and the 40 mm window lets the operator dial the press stroke between 110 and 150 mm per part.
Carton flap tucker
On a packaging line the 150 mm reach folds tall flaps into shallow frames, and the fitted -S magnet with a DMSE switch confirms each fold cycle at the retracted end.
Lab sample elevator
Raising a tray of sample vials about 8 kg vertically with a 2:1 margin, the short ISO 21287 body fits inside the instrument housing where a full-length profile cylinder will not.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-40S with the ACEJ20X150-40S
At 0.5 MPa this bore 20 gives 157.1 N push; step down to bore 16 (100.5 N) for lighter clamps or up to bore 25-class sizes when you need more force in the same short body. The 40 mm window means the stop screw can only shorten the extend stroke to 110 mm - it never lengthens past 150 mm, and 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 plus I/Y rod knuckles bolt straight to the ISO 21287 face. The female M6x1.0 rod thread and M5x0.8 ports are standard here. Before ordering, confirm the ACEJ20X150 replacement matches your fixture, since the ACP is DIN-standard and ISO 21287 dimensions differ slightly.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X150-40S
- ✓ 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 ACPJ20X150-40S 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 gives a 40 mm adjustment window, so the stop screw trims the 150 mm extend stroke down to 110 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
The ACPJ family is discontinued; the current drop-in is the ACEJ20X150, which matches the same bore, stroke and force class in the ISO 21287 short-body format. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, because the ACP is DIN-standard. This -S version carries the optional magnet, so CMSE and DMSE reed or solid-state switches mount directly; versions without the -S code have no magnet.
