This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X65S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X65S 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 ACPD40X65S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 65mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X65S (ISO 21287 ACE), in the same bore, stroke and force class.
This is a double acting compact cylinder with a rod leaving both covers, so the 40 mm bore delivers the same 571.8 N at 0.5 MPa (800.5 N at 0.7 MPa) whether it pushes or pulls - both strokes work on the rod-side area. The through-rod resists rotation and light side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end, and speed runs 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 jigs and guarding. At 0.5 MPa the 571.8 N output equates to about 58 kg of lift; halve that for a 2:1 margin and it will raise roughly 29 kg vertically with room to spare. Note that this model is discontinued - the current-production drop-in is the ACED40X65, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X65S (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. |
| ×65 | 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 through-rod lets a jig clamp from either cover with identical 571.8 N force at 0.5 MPa, so one cylinder serves both a clamp and a support side on a machining fixture.
With the -S magnet fitted, CMSE or DMSE switches confirm extend and retract on a carton pusher running at 30-500 mm/s, while the 65 mm stroke clears a 60 mm lane.
Equal force in both directions makes the double rod ideal for a fatigue or cycle-test carriage that must stroke back and forth against the same 800.5 N at 0.7 MPa.
Size both ways before ordering: the 32 mm bore gives 345.6 N at 0.5 MPa, while the 50 mm bore reaches 881.2 N - pick the 40 mm when your fixture needs its 571.8 N equal-force output in both directions. The 65 mm stroke sits well inside the 200 mm maximum standard stroke for this bore, so it ships as a standard build. Remember that a plain double-rod cylinder drifts when air is lost; add a rod lock or pilot check if the load must stay put. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly on the body. For new designs, order the ACED40X65 instead - same bore, stroke and force class.
Replacement checklist
Yes - because a rod exits both covers, both strokes use the rod-side area. The figures are 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, equal push and pull, with a maximum of about 116.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, and the rod end carries a female M8x1.25 thread with a 1/8" port.
The hard-anodized aluminium body follows the short ISO 21287-class format, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange or LB foot mounting and fixed TPU bumpers at both ends. The ACPD family is discontinued; the current-production drop-in is the ACED40X65 - swap the P for an E - and you should confirm the ISO 21287 mounting dimensions before the swap.
