This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X160-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X160-20 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 ACPJ20X160-20 is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 160mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X160-20 (ISO 21287 ACE), in the same bore, stroke and force class.
The ACPJ20X160-20 is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 160 mm stroke by up to 20 mm on site, giving a usable range of 140-160 mm. At the 20 mm bore it delivers 157.1 N push and 117.8 N pull at 0.5 MPa, rising to 219.9 N push at 0.7 MPa. The 160 mm stroke exceeds the 100 mm maximum standard stroke for this bore, so it is a made-to-order build. This model is discontinued; the current-production replacement is ACEJ20X160.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and guarding where a full-length body cannot. A fixed TPU bumper sits at both ends, and the hard-anodized aluminium body pairs with an S45C hard-chrome rod. For sizing, plan on roughly 94 N of real work at 0.5 MPa (about 0.6 of the push rating), which corresponds to lifting about 9 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-20 (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 ACEJ20X160-20 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. |
| ×160 | Stroke length in mm. |
| -20 | 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).
Raises small fixture plates of about 9 kg on a PCB handling gantry, with the 20 mm stop window dialing the lift height between 140 and 160 mm to match tray levels.
Applies roughly 94 N of usable clamping force at 0.5 MPa to seat connectors in an electronics assembly jig where a full-length body will not fit.
Pushes undersized cartons off a narrow conveyor lane, with the adjustable stroke trimming throw to the lane width without re-plumbing.
Size both ways: if 157.1 N push at 0.5 MPa is more than you need, the 16 mm bore gives 100.5 N; if you need more, step up to the 25 mm class. Remember the stop screw is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so it is not a load-holding lock. FA/FB flange and LB foot mountings bolt to the standard face. This unit has no magnet (the optional -S code adds one for CMSE / DMSE switches). Order ACEJ20X160 as the current drop-in and confirm ISO 21287 mounting dimensions before swapping.
Replacement checklist
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa push is 219.9 N and pull 164.9 N. Theoretical maximum is 32 kgf at 1.0 MPa. 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.
The -20 code gives a 20 mm window: a stop screw shortens the 160 mm extend stroke to any length down to 140 mm. The model is discontinued; ACEJ20X160 is the current ISO 21287 drop-in with the same bore, stroke and force class - confirm mounting dimensions before swapping.
