This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X65B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X65B 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 ACPD40X65B 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 ACED40X65B (ISO 21287 ACE), in the same bore, stroke and force class.
A double acting compact cylinder with a rod leaving both covers, the ACPD40X65B delivers 571.8 N in each direction at 0.5 MPa, because both strokes work on the rod-side area of the 40 mm bore. The 65 mm stroke sits well inside the 200 mm standard range for this bore, and the male rod thread (B code) on each 12 mm rod end takes a male-threaded knuckle without adapters. A fixed TPU bumper at each cover takes the end-of-travel hit.
The hard-anodized aluminium body follows the ISO 21287 short format, so it saves roughly 50% of the mounting length of an ISO 15552 profile cylinder - useful inside machine guards and slide fixtures. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, temperature -20 to +70 C. At 0.5 MPa plan on about 343 N of usable work, which is roughly 29 kg of vertical lift with a 2:1 margin. Note: this model is discontinued; the current-production successor is ACED40X65.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X65B (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 front rod pushes a machined aluminum housing off the fixture while the rear rod trips a part-present flag on the same stroke.
Equal 571.8 N force in both directions centers PET bottles into lanes at up to 500 mm/s without a return-side force drop.
The through-rod mounts a cross-slide between two covers, resisting side load in a gantry that shifts small castings between pallets.
For a 65 mm stroke needing about 570 N both ways, the 40 mm bore is the right size; step down to the 32 mm bore (345.6 N at 0.5 MPa) for lighter clamps or up to the 50 mm bore (881.2 N) for heavier press fits. The piston drifts when air is lost, so add a rod lock or pilot check valve if the load must stay put. Mounting bolts to the FA/FB flange or LB foot face, and CMSE / DMSE switches only work if you order the -S magnet code - this unit has no magnet. Replace with ACED40X65 and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
Yes - the double-rod design exposes the rod-side area on both strokes, so force is equal each way: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, 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. The 12 mm rod ends are male threaded (B code) and the air port is 1/8" PT.
The hard-anodized aluminium body follows the ISO 21287 short format, cutting about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each cover. FA/FB flange and LB foot brackets bolt to the standard face. The ACPD40X65B is discontinued; the current drop-in is ACED40X65 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before ordering.
