This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X110-40SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X110-40SB 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.

The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X110-40SB 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 ACEJ20X110-40SB (ISO 21287 ACE), in the same bore, stroke and force class.
This is a double acting compact cylinder with an adjustable extend stroke: the -40 stop screw trims the 110 mm stroke by up to 40 mm on site, giving a usable range of 70-110 mm. At 0.5 MPa the 20 mm bore delivers 157.1 N push and 117.8 N pull, rising to 219.9 N at 0.7 MPa, with a theoretical peak of 32 kgf at 1.0 MPa. The 110 mm stroke exceeds the 100 mm standard limit for this bore, so it is a made-to-order build. Note: the ACPJ family is discontinued; the current-production drop-in is ACEJ20X110.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and guarding. A fixed TPU bumper sits at both ends and only decelerates the piston - it never locks or holds a load. Because this model carries the optional -S magnet, CMSE / DMSE reed or solid-state switches can be fitted for position feedback. As a sizing rule of thumb, plan on roughly 94 N of real work at 0.5 MPa (about 60% of the push rating), which corresponds to lifting around 9 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X110-40SB (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.
| 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 ACEJ20X110-40SB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| ACPJ | DIN compact cylinder (adjustable-stroke, discontinued). |
|---|---|
| 20 | Bore size in mm. |
| ×110 | Stroke length in mm. |
| -40 | Adjustable stroke window (mm the extend stroke can be shortened on site). |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (adjustable stroke).
A 70-110 mm adjustable stroke lets a jig builder trim clamp travel per pallet, with the 157.1 N push at 0.5 MPa holding light aluminum parts during machining.
The male rod thread and 40 mm trim window make it easy to set the exact eject distance for pushing misaligned cartons off a conveyor at 30-500 mm/s.
With the fitted -S magnet and CMSE / DMSE switches, an assembly station confirms up and down positions while lifting parts of about 9 kg or less vertically.
Size both ways before ordering: the 16 mm bore gives 100.5 N push at 0.5 MPa if your load is lighter, while the next class up in the ACE range covers heavier duties. The 40 mm window suits fixtures where the final stroke is tuned during commissioning - remember the stop only shortens the extend stroke and drifts on air loss, so it is not a load-holding brake. FA/FB flange and LB foot mountings plus the male (B) rod thread bolt into standard ISO 21287 fixtures. Confirm the ISO 21287 mounting dimensions before swapping to ACEJ20X110, since the ACP is DIN-standard.
Replacement checklist
Push is 157.1 N and pull 117.8 N at 0.5 MPa; at 0.7 MPa push rises to 219.9 N and pull to 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. It is double acting, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, port M5x0.8, rod 10 mm with male thread, and a 40 mm stroke adjustment window over the 110 mm stroke. This stroke is made to order since the bore's standard maximum is 100 mm.
No - the ACPJ series is discontinued. The current-production drop-in is ACEJ20X110, which swaps the P for an E and 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 was built to the DIN standard.
