This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X110S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X110S 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 ACP20X110S is a double acting 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 ACE20X110S (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP20X110S is a double acting DIN-standard compact cylinder with a 20 mm bore and a 110 mm stroke, driven by air in both directions and fitted with fixed TPU bumpers at each end. At 0.5 MPa it pushes with 157.1 N and pulls with 117.8 N, rising to 219.9 N and 164.9 N at 0.7 MPa, with a theoretical peak of 32 kgf at 1.0 MPa. The 110 mm stroke is longer than the 100 mm standard limit for this bore, so it is made to order. The -S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped onto the hard-anodized aluminium body.
Because the short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, it suits tight jigs and guarding where a full-length body will not fit. For real-world sizing, plan on about 94 N of usable push at 0.5 MPa, which lifts roughly 4.8 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production replacement is ACE20X110, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X110S (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 ACE20X110S 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. |
| ×110 | 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).
The 157.1 N push at 0.5 MPa clamps small aluminium brackets in drilling fixtures, and the short body fits where a full-length profile cylinder cannot.
With the -S magnet fitted, CMSE or DMSE switches confirm extend and retract on a 110 mm ejection stroke in electronics assembly equipment.
About 94 N of usable force at 0.5 MPa presses dowels or labels into plastic housings on a benchtop fixture, lifting roughly 4.8 kg vertically with margin.
If 157.1 N of push at 0.5 MPa is marginal for your load, step up to the 25 mm bore (245.4 N); if the load is light and space is tight, the 16 mm bore delivers 100.5 N. The female M6x1.0 rod thread accepts standard I/Y knuckles, and FA/FB flange, LB foot or CA/CB clevis mounts bolt to the same face. A plain cylinder drifts when air is lost, so add a rod lock or pilot check valve for held loads. Order ACE20X110 as the current drop-in and verify the ISO 21287 footprint.
Replacement checklist
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa, 219.9 N push and 164.9 N pull; theoretical maximum is 32 kgf at 1.0 MPa. It is a double acting compact cylinder with a 20 mm bore, 110 mm made-to-order stroke, 10 mm rod, M5x0.8 ports, 0.15-1.0 MPa (22-145 psi) operating pressure, 30-500 mm/s speed and fixed TPU bumpers both ends.
Order ACE20X110, the current ISO 21287 successor: swap the P for an E and you get the same bore, stroke and force class in a matching short body. Because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. The ACE family also covers related types such as ASP/ATP, ACPD and ACPJ.
