This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X60-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X60-40S 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 ACPJ20X60-40S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X60-40S is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 60mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X60-40S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X60-40S
The ACPJ20X60-40S is a double acting, adjustable-stroke compact cylinder (now discontinued) with a 20 mm bore and 60 mm stroke. Its ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and gantries. The -40 code gives a 40 mm adjustment window: a stop screw trims the extend stroke anywhere from 20 mm to 60 mm on site, and fixed TPU bumpers pad both ends. 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. The S code means the magnet is fitted, so CMSE or DMSE switches can read position directly.
For sizing, plan on roughly 94 N of real work at 0.5 MPa (about 60% of the push rating), which lifts about 9 kg vertically - halve that to about 4-5 kg if you want a 2:1 margin on a vertical lift. The hard-anodized aluminium body carries an S45C hard-chrome 10 mm rod with a female M6x1.0 thread, M5x0.8 ports, and runs 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s. This model is discontinued: the current drop-in is the ACEJ20X60 (swap the P for an E) in the same bore, stroke and 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 ACEJ20X60-40S (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 ACEJ20X60-40S 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 ACPJ20X60-40S Is Used
Fixture clamping on a CNC jig
The 20-60 mm trimmed stroke clamps varied part heights on a machining fixture, with 157.1 N push at 0.5 MPa holding light steel brackets in place.
Position-checked ejector on a packaging line
With the -S magnet fitted, CMSE switches confirm each 60 mm eject stroke on a carton tray line, and the stop screw shortens travel for shallow trays.
Stopper gate on a small-parts conveyor
The short ISO 21287 body fits under low conveyor frames, and about 9 kg of vertical lift capacity at 0.5 MPa raises a light stopper arm reliably.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X60-40S with the ACEJ20X60-40S
At 157.1 N push (0.5 MPa), the 20 mm bore sits between the 16 mm bore (100.5 N) and the 32 mm class above it - step up if your tooling needs more than about 94 N of usable force. The 60 mm stroke with a 40 mm trim window suits stations where one cylinder must serve several stop positions. Note the stop screw is a mechanical end stop for the extend stroke only: it does not hold a load if air is lost. FA/FB flange or LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches. Order the ACEJ20X60 as the current-production replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X60-40S
- ✓ 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 ACPJ20X60-40S FAQ
Push is 157.1 N and pull 117.8 N at 0.5 MPa; at 0.7 MPa push is 219.9 N and pull 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. It is double acting, 20 mm bore, 60 mm stroke with a 40 mm adjustment window (usable 20-60 mm), M5x0.8 ports, female M6x1.0 rod thread, TPU bumpers both ends, 0.15-1.0 MPa (22-145 psi) operating pressure, 30-500 mm/s speed, and -20 to +70 C temperature range.
Order the ACEJ20X60, the current-production ISO 21287 successor: swap the P for an E and you get the same bore, stroke and force class in a matching short body. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping, and re-check FA/FB flange or LB foot hole patterns.
