This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X35B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X35B 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 ACP20X35B 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 ACE20X35B (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP20X35B is a double acting compact cylinder in the DIN-standard ACP family, with a 20 mm bore, 35 mm stroke and a male rod thread from the B code. It pushes 157.1 N and pulls 117.8 N at 0.5 MPa, rising to 219.9 N at 0.7 MPa, and its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and guarding where a full-length body will not. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at each end.
This model is discontinued; the current-production drop-in is ACE20X35, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. Because no S code was ordered, there is no magnet fitted, so CMSE or DMSE switches cannot be used; order the -S variant if position sensing is needed. For sizing, plan on roughly 94 N (about 9.6 kg) of real work at 0.5 MPa, or a vertical lift of about 8 kg with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X35B (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 ACE20X35B 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).
The 35 mm stroke and 157.1 N push at 0.5 MPa clamp small aluminium or plastic workpieces in milling and drilling jigs where the short body must fit inside the fixture footprint.
With about 9.6 kg of usable thrust at 0.5 MPa, this cylinder ejects lightweight cartons or blisters from a conveyor lane in compact packaging heads.
The 20 mm bore delivers controlled low-force pressing for vial capping and sample preparation rigs, running 30-500 mm/s under 0.15-1.0 MPa (22-145 psi) supply.
At 20 mm bore this sits between the 16 mm ACP (100.5 N push at 0.5 MPa) and the 25 mm ACP (245.4 N push), so step up to 25 mm if your load needs more than about 94 N of usable thrust. The male rod thread suits direct attachment to I/Y knuckles on the ISO 21287 mounting face, with FA/FB flange, LB foot and CA/CB clevis brackets available. Remember the piston drifts when air is lost - add a rod lock or pilot check valve for held loads - and choose ACE20X35 as the current replacement.
Replacement checklist
At 0.5 MPa it 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. The model is discontinued - the current drop-in is ACE20X35 (same 20 mm bore, 35 mm stroke and force class); confirm ISO 21287 mounting dimensions before swapping.
It is a compact double-acting cylinder with a hard-anodized aluminium body, S45C hard-chrome 10 mm rod, M5x0.8 ports, fixed TPU bumpers at both ends and a male rod thread from the B code. Sensing requires the optional -S magnet code, which enables CMSE or DMSE switches; this version has no magnet fitted.
