This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X175 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X175 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 ACPD100X175 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø100mm bore and 175mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED100X175 (ISO 21287 ACE), in the same bore, stroke and force class.
This is a double acting, double-rod compact cylinder built to the DIN-standard ACP format: a 100 mm bore pushing 3681.6 N in BOTH directions at 0.5 MPa (5154.2 N at 0.7 MPa), because the rod-side area works on each stroke. A 25 mm rod exits both covers, so the rear rod can carry a sensor flag or a second tool while the through-rod resists rotation and side load. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits tight gantries and press fixtures. Note: the ACPD family is discontinued; the current-production drop-in is the ACED100X175, so confirm ISO 21287 mounting dimensions before swapping.
Practical sizing: plan on roughly 2209 N of real work at 0.5 MPa rather than the full rating, which is about 187 kg of vertical lift with a 2:1 margin. The 175 mm stroke sits inside the 300 mm max standard stroke for this bore, so it is a catalog item, not a made-to-order build. Air supply is 0.15-1.0 MPa (22-145 psi) filtered to 40 um, speed range 30-500 mm/s, and fixed TPU bumpers decelerate both ends. The magnet is not fitted on this code; order the -S version if you need CMSE / DMSE switch positions.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X175 (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 | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 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). |
|---|---|
| 100 | Bore size in mm. |
| ×175 | 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 3681.6 N force in both directions lets one 100 mm bore press a bearing in on the forward stroke and eject it on the return, with the 175 mm stroke clearing the part between cycles.
A through-rod head on a Z-axis gantry lifts about 187 kg vertically with a 2:1 margin at 0.5 MPa, while the rear rod carries a flag for CMSE or DMSE switches on the -S version.
The rear rod drives a product stop from the opposite side of the line, so one cylinder does two jobs; the short body fits between conveyor frames where a full-length profile cylinder will not.
At 3681.6 N per direction at 0.5 MPa, this 100 mm bore covers heavy clamping and lifting; step down to the 80 mm bore (2356.2 N) for lighter loads or accept that the next size up does not exist in this family. Because force is equal both ways, the same rating applies whether you push or pull. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay put. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches. For new designs, order the ACED100X175 instead - same bore, stroke and force class.
Replacement checklist
Yes - the double-rod design uses the rod-side area on both strokes, so force is equal both ways: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa, with a maximum of 750.8 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 1/4" port depends only on the 100 mm bore.
Order the ACED100X175, the current-production ISO 21287 successor: swap the P for an E and you get the same 100 mm bore, 175 mm stroke and force class. The ACP is DIN-standard, so confirm the ISO 21287 mounting dimensions against your fixture before swapping, and remember the magnet is only present when the -S code is ordered.
