This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X150-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X150-10 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 ACPJ20X150-10
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-10 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 ACEJ20X150-10 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-10
The ACPJ20X150-10 is a double acting compact cylinder with an adjustable extend stroke: the -10 code gives a 10 mm trim window, so a stop screw on the head lets you dial the effective stroke anywhere between 140 and 150 mm on site. Air drives the rod out and pulls it back, a fixed TPU bumper sits at each end, and the 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa (219.9 N push at 0.7 MPa). The 150 mm stroke is longer than the 100 mm standard maximum for this bore, so it is a made-to-order build.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters in slim gantries and guarded stations. In practice the 157.1 N push at 0.5 MPa supports about 94 N of real work once you keep a margin, and that is roughly an 8 kg vertical lift at a 2:1 safety factor. Note this model is discontinued: the current-production replacement is the ACEJ20X150, and you should confirm ISO 21287 mounting dimensions before swapping. There is no magnet fitted, so position switches cannot be used unless you order the optional -S version.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X150-10 (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 ACEJ20X150-10 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 ACPJ20X150-10 Is Used
Pick-and-place drop station
The 150 mm stroke with a 10 mm trim window lets a packaging line lower a tray onto a datum and fine-tune the release height without shimming, using about 94 N of usable push at 0.5 MPa.
Bench-top press fixture
A small electronics assembly jig can use the 219.9 N push at 0.7 MPa to seat connectors or press-fit bushings, with the stop screw setting exact depth within the 140-150 mm range.
Gantry ejector on a compact frame
Where a full-length profile cylinder will not fit under a guard, the short body plus LB foot mounting ejects finished parts from a machining fixture at 30-500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-10 with the ACEJ20X150-10
Size the bore against load: the 16 mm bore gives 100.5 N push at 0.5 MPa, while stepping up to the next frame class adds force headroom if your part weight creeps toward the 8 kg vertical-lift figure. The 10 mm adjuster only shortens the extend stroke, it never lengthens it past 150 mm, and it is a mechanical end stop rather than a mid-stroke lock, so the rod can still drift if air is lost. FA/FB flange and LB foot mountings bolt to the standard face. This unit is discontinued; order the ACEJ20X150 as the drop-in successor and verify the ISO 21287 hole pattern first.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X150-10
- ✓ 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 ACPJ20X150-10 FAQ
At 0.5 MPa the 20 mm bore 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. Plan on roughly 94 N of real work at 0.5 MPa, which is about an 8 kg vertical lift with a 2:1 margin. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
The -10 code adds a stop screw that shortens the extend stroke by up to 10 mm, giving a usable 140-150 mm range; it cannot extend past 150 mm and it does not hold load if air is lost. The 150 mm stroke is made to order because the bore 20 standard maximum is 100 mm. This ACPJ is discontinued: the current-production drop-in is the ACEJ20X150 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. Position sensing needs the optional -S magnet with CMSE or DMSE switches; this version has no magnet.
