This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X175S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X175S 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 ACPD100X175S 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 ACED100X175S (ISO 21287 ACE), in the same bore, stroke and force class.
Double acting with a rod leaving both covers, the ACPD100X175S pushes and pulls with identical force: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa in each direction, because both strokes work on the rod-side area of the 100 mm bore. The through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. Speed range is 30-500 mm/s and the fixed TPU bumper at each end takes the end-of-stroke hit.
The hard-anodized aluminium body follows the ISO 21287 short format, cutting roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight presses and gantries. Running pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, on air filtered to 40 um, from -20 to +70 C. This model carries the optional -S magnet, so CMSE / DMSE switches mount directly. Note it is discontinued: the current drop-in is ACED100X175. As a sizing rule, plan on about 2209 N of real work at 0.5 MPa, which lifts about 112 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X175S (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 3681.6 N push and pull at 0.5 MPa lets one cylinder compact and retract a platen in a small workshop baler, with the 175 mm stroke covering a deep bin.
Equal force in both directions drives a mixing carriage back and forth at up to 500 mm/s, and the through-rod keeps the tray from twisting.
With about 112 kg of vertical lift capacity at a 2:1 margin, the cylinder lowers and raises a fixture drop table, and CMSE switches via the -S magnet flag end positions.
At 100 mm bore this is the top of the ACPD range, delivering 3681.6 N both ways at 0.5 MPa; step down to the 80 mm bore for 2356.2 N, or move to a larger bore only if you need beyond 3681.6 N per direction. The 175 mm stroke sits inside the 300 mm maximum standard stroke for this bore, so no made-to-order build is needed. Remember the piston drifts if air is lost - add a rod lock or pilot check where a load must stay put. FA/FB flange or LB foot mounting bolts to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches. Since ACPD is discontinued, order ACED100X175 as the current-production equivalent and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
Yes - because a rod exits both covers, every stroke uses the rod-side area of the 100 mm bore. Output is 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa in each direction, equal both ways. At 1.0 MPa the peak is 750.8 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof is 1.5 MPa (215 psi), speed is 30-500 mm/s, and the port is 1/4" (PT thread).
AirTAC no longer produces the ACPD family. The current drop-in is ACED100X175, the ISO 21287 successor: swap the P for an E and you get the same 100 mm bore, 175 mm stroke and force class in the same short-body format. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to the older DIN-standard pattern.
