This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X35S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X35S 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 ACP Compact Cylinder ACP20X35S is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X35S (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP20X35S is a double acting compact cylinder in the DIN-standard ACP series, with a 20 mm bore, 35 mm stroke and a 10 mm hard-chrome rod on an S45C shaft. Air drives the piston both ways, and fixed TPU bumpers sit at each end. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, rising to 219.9 N push at 0.7 MPa. 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 guarding where a full-length body cannot.
This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the barrel for end-of-stroke sensing. Plan on about 94 N of usable push at 0.5 MPa (roughly 60% of the rating), which is about 9 kg of vertical lift with a 2:1 margin. Note the ACP family is discontinued: the current-production drop-in is ACE20X35, same bore, stroke and force class, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X35S (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 ACE20X35S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| ACP | DIN compact cylinder (double-acting, discontinued). |
|---|---|
| 20 | Bore size in mm. |
| ×35 | Stroke length in mm. |
| 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).
With 157.1 N push at 0.5 MPa, the 20 mm bore clamps brackets or machined caps in drilling jigs, and the short body fits inside the jig plate footprint.
The fitted -S magnet lets a CMSE or DMSE switch confirm full extension on a 35 mm eject stroke for a small electronics assembly station.
About 9 kg of practical vertical push at 0.5 MPa suits seating bushings or labels onto small housings on a benchtop press fixture.
For a 35 mm stroke at this force level, the 20 mm bore is a sensible middle choice: a 16 mm bore gives 100.5 N push at 0.5 MPa while a 25 mm bore raises it to 245.4 N, so step up if your part weight or friction load sits near the 20 mm limit. Keep in mind a plain cylinder drifts when air is removed - add a rod lock or pilot check valve if the load must stay put. The M6x1.0 female rod thread takes standard I/Y knuckles, and FA/FB flange, LB foot or CA/CB clevis mounts bolt to the same face. Because this model is discontinued, order ACE20X35 as the current equivalent and verify the ISO 21287 footprint first.
Replacement checklist
At 0.5 MPa it delivers 157.1 N push and 117.8 N pull; at 0.7 MPa, 219.9 N push and 164.9 N pull. Theoretical maximum is 32 kgf at 1.0 MPa. Rod speed is 30-500 mm/s over an operating range of 0.15-1.0 MPa (22-145 psi), with proof pressure of 1.5 MPa (215 psi).
The short-body build saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot and CA/CB clevis options on the standard face. This S-coded model includes the optional -S magnet for CMSE / DMSE switches. The ACP line is discontinued; ACE20X35 is the current drop-in, so confirm ISO 21287 mounting dimensions before ordering.
