This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X35S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X35S 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 ACPD Double Rod Compact Cylinder ACPD40X35S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 35mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X35S (ISO 21287 ACE), in the same bore, stroke and force class.
A double acting, double-rod compact cylinder built to the DIN-standard ACP pattern, the ACPD40X35S pushes a 40 mm piston through a 35 mm stroke with a rod leaving both covers. Because both strokes work on the rod-side area, output is equal in each direction: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa. The through-rod resists rotation and side load, gives a symmetric mounting face, and the rear rod can carry a sensor flag, while fixed TPU bumpers pad both ends of travel at 30-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guarding and gantry frames. In practical terms, plan on about 343 N (roughly 35 kg of push) of usable work at 0.5 MPa, and expect it to lift about 29 kg vertically with a 2:1 margin. Note that this model is discontinued: the current-production drop-in is the ACED40X35, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X35S (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 572 N |
| 0.7 MPa | 800 N |
| Max (@1.0 MPa) | 117 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).
| ACPD | DIN compact cylinder (double-rod, discontinued). |
|---|---|
| 40 | 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 equal 571.8 N force in both directions lets one 35 mm stroke clamp and release a machined housing in a CNC jig with identical pressure each way.
A rod on each cover drives a pick-and-place slide forward and back with matched force, the through-rod resisting the side load of the tooling plate.
With the -S magnet already fitted, CMSE or DMSE switches confirm press-fit completion on a compact electronics assembly head where space is short.
At 571.8 N per side at 0.5 MPa, the 40 mm bore sits between the 32 mm (345.6 N) and 50 mm (881.2 N) options - step down for lighter clamping, up when the load needs more margin. Remember that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay put. This -S version carries the optional magnet, so CMSE / DMSE switches can be fitted for end-of-stroke signalling, and FA/FB flange or LB foot mounts bolt to the standard face. Order the ACED40X35 as the current replacement.
Replacement checklist
Yes - the double-rod design works on the rod-side area in both directions, so the ACPD40X35S delivers 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa either way, with a maximum of 116.6 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 12 mm rod ends in a female M8x1.25 thread with a 1/8" PT port.
The hard-anodized aluminium body follows the compact DIN-standard ACP format, cutting about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends. The ACPD family is discontinued; the current-production successor is the ACED40X35 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before you swap.
