This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE16X40SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE16X40SB 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 ACP16X40SB is a double acting DIN-standard tight/compact air cylinder with a Ø16mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE16X40SB (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP16X40SB is a double acting compact cylinder in the discontinued AirTAC ACP DIN-standard series, with a 16 mm bore and 40 mm stroke. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those rise to 140.7 N and 105.6 N, with a theoretical peak of 20.5 kgf at 1.0 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 where a full-length body cannot. The S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly on the hard-anodized aluminium body.
Practically, plan on about 60 N (roughly 6 kg of force) of usable work at 0.5 MPa instead of the full 100.5 N rating; halving the vertical-lift equivalent of about 10 kgf gives a 2:1 margin, so this cylinder comfortably lifts about 5 kg vertically. The B code gives a male rod thread on the 8 mm rod, the port is M5x0.8, and a fixed TPU bumper sits at each end. Note this model is discontinued: the current-production drop-in is ACE16X40, and buyers should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE16X40SB (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 | 101 N | 75 N |
| 0.7 MPa | 141 N | 106 N |
| Max (@1.0 MPa) | 21 kgf | |
The ACE16X40SB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

|---|---|
| 16 | Bore size in mm. |
| ×40 | Stroke length in mm. |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |

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 fitted -S magnet lets a CMSE or DMSE switch confirm end-of-stroke on a 40 mm slide, while the 100.5 N push at 0.5 MPa seats light connectors or clips.
With about 6 kg of usable clamping force at 0.5 MPa and a body roughly 50% shorter than an ISO 15552 profile cylinder, it clamps PCB trays inside crowded jig plates.
The 140.7 N push at 0.7 MPa ejects finished components weighing up to about 5 kg from a nest, with the male rod thread picking up an I/Y knuckle directly.
At 16 mm bore you sit between the 12 mm size (56.5 N push at 0.5 MPa) and the 20 mm size (157.1 N push at 0.5 MPa); if your load needs more than about 60 N of real work, step up to the 20 mm bore. The 40 mm stroke is well inside the 75 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order length. The male rod thread (B) suits I/Y rod 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 if the load must be held. Order ACE16X40 as the current replacement and verify the ISO 21287 mounting dimensions first.
Replacement checklist
Double acting on a 16 mm bore: push 100.5 N and pull 75.4 N at 0.5 MPa; push 140.7 N and pull 105.6 N at 0.7 MPa; theoretical maximum 20.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, rod 8 mm with male thread, port M5x0.8. The model is discontinued; ACE16X40 is the drop-in replacement.
The S in ACP16X40SB means the optional -S magnet is fitted, so CMSE reed or DMSE solid-state switches clamp onto the aluminium body for end-of-stroke signalling. Without the -S code there is no magnet in the piston. Also note the fixed TPU bumpers only decelerate at the ends - they do not hold the load, so use a rod lock or pilot check valve where a held position matters.
