This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X100-75SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X100-75SB 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 ACPJ20X100-75SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-75SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X100-75SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-75SB
This AirTAC ACPJ20X100-75SB is a double acting compact cylinder with an adjustable extend stroke: the -75 stop screw trims the 100 mm stroke down to as short as 25 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, with a theoretical peak of 32 kgf at 1.0 MPa. Running on 0.15-1.0 MPa (22-145 psi) filtered air at 30-500 mm/s, it carries a fixed TPU bumper at both ends and a male rod thread (B code).
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guards. Because 0.6 of the push force is a practical working figure, plan for about 94 N of real work at 0.5 MPa - roughly 9 kg lifted vertically with a 2:1 margin. Note this model is discontinued: the current-production replacement is the ACEJ20X100, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X100-75SB (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 ACEJ20X100-75SB 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 ACPJ20X100-75SB Is Used
Benchtop ejection fixture
The 157.1 N push at 0.5 MPa ejects small machined aluminium parts from a drill jig, with the 25-100 mm trim range tuned to each fixture plate.
Pick-and-check gantry
With the fitted -S magnet and CMSE / DMSE switches, the cylinder reports extend and retract positions on a compact electronics-test gantry.
Carton hold-down clamp
About 9 kg of vertical working force at 0.5 MPa holds cosmetic cartons steady during a labelling pass on a small packaging line.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X100-75SB with the ACEJ20X100-75SB
At 20 mm bore you sit above the 16 mm size (100.5 N push at 0.5 MPa) and below the 25 mm class, so choose this bore when a small cylinder falls short but space is still tight. The 75 mm window suits jobs where the final position is tuned during commissioning. Remember the stop screw is a mechanical end stop, not a mid-stroke lock - the rod drifts if air is lost. This unit carries the optional -S magnet, so CMSE / DMSE switches can be added, and the male rod thread suits I/Y knuckles. Order the ACEJ20X100 as the current drop-in and verify ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X100-75SB
- ✓ 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 ACPJ20X100-75SB FAQ
At 0.5 MPa the 20 mm bore gives 157.1 N push and 117.8 N pull; at 0.7 MPa it reaches 219.9 N push and 164.9 N pull, with a theoretical maximum of 32 kgf at 1.0 MPa. The -75 stop screw shortens the 100 mm extend stroke by up to 75 mm, giving a usable 25-100 mm range. It is a mechanical end stop only - on air loss the piston still drifts. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends.
No - the ACPJ family is discontinued. The current-production replacement is the ACEJ20X100, which swaps the P for an E and matches the same bore, stroke and force class in the ISO 21287 short-body format. Before swapping, confirm the ISO 21287 mounting dimensions against your fixture, since the ACP was built to a DIN-standard footprint. The FA/FB flange and LB foot options carry over, and the -S magnet option enables CMSE / DMSE switches.
